True story... More than 50 years ago, when I was just a kid, the owner of a local oil field welding and machine shop got sued in Federal Court for "stealing" electricity from the 240KV power lines which passed over his property, by way of using a homemade induction coil mounted on a pole. Which in turn was wired into his electrical system, and which had been powering his business for more more than 20 years already. The court ruled that he could not be sued for taking advantage of natural physics, and dismissed the case on day one. His business continued to thrive for another 30 years until his death. Shit you not.
Great story! Of course, it was the court that was clueless about the physics - or the law for that matter. The intent of the business owner was clear: steal electricity.
@@davidedickjr More like taking advantage of the environmental conditions of his property. How is it different than if the power company built a large concave mirrored glass headquarters that focuses on your property and you taking advantage of the concentrated solar energy that the building provides?
@@magicone9327i have those lines across my property that are constantly causing me grief. It would be nice to get some benefit from them. How do i set that up?
As an electrician, I was called out to a site where a crew was setting up a manufactured home under high voltage lines. The set up crew was getting shocked every time they touched the metal frame of the house. My volt meter showed 110 volts AC from the frame to ground. I put ground rods at each corner and wished them luck. Would hate to be living in that house...

@@fredriksjoblom5161most high voltage go under ground.. in Northern Europe. In the 70s my room was maybe 20 meters from the high voltage lines coming into my town of about 30k. And the transformers to step it down was in my garden in a big concrete building… my grandpa was a plant manager at the electric company.
I knew a man who was in charge of maintaining lines like these. His crew informed him that a property owner had installed an array of wires on his property near the towers. They thought that he was stealing electricity. Management said that if he was smart enough to capture the electricity that they were losing, he was entitled to it.
@@marilynbridges8697 Electrical Engineer here. Unfortunately it isn't waste-energy... it's electromagnetically-coupled (like a gigantic transformer the size of a locomotive), but with a huge air-gap in the middle of the transformer. Any coupling through the air takes power away from the system. No free lunch here, unfortunately... it would be cool if it was free waste-energy for the taking though! =)
It is stealing electricity no matter how you look at it. A transformer hanging on the pole outside your house is in no way mechanically connected. It has two coils and the voltage comes from a primary coil to a low voltage coil thru induction. There is no loss. You are still putting load on the line. This is my 27th year as a journeyman lineman and I have seen everything you can see.
As a retired building inspector, I have seen why all buildings must stay back from high-tension, high-power lines. Among many reasons, electricity can arc through Smoke, especially high-particulate smoke such as that from a wood stove (or solid-fuel burning appliance). Electricity can travel a long distance through smoke. But of course there are Electromagnetic reasons to stay back as well. This video illustrates an example of that electromagnetic energy.
Arc discharge in volcanic plumes is an example at scale. Dusty plasma in "Space" aligns in filaments that stretch light years. Though effectively a vacuum in material terms fluctuating field effects permeate and inform an electric Universe - not just at atomic scale. I was wondering recently if ferrous ions might be offgassed by my wood stove. I have noted migrating rust-colouring to some rocks on the top. I hadn't thought of smoke to local power lines - but I've never felt anything sparky from touching the stove. Other particulates may also operate your observation - such as dust or pollen. Lots of nano-particulates now sprayed to save the planet. I don't know if they descend without molecular bonding (ie water vapour) atmospheric capacitance isn't just a voltage gradient but a leaky dielectric we call weather (or even climate).
I'm a fencing contractor and I can say that I have put up several fences up under overhead power lines and sometime it will shock to piss out of you touching the fence.
Fences near an ehv line should be grounded. If it’s not an electric fence you can ground through standard grounding rods. If it’s electric you need to use an electric fence filter or shock filter. There are several manufacturers that make these.
I remember a story about 20 yeas ago. A farmer kept having bad problems with his cattle. Over a long time he finally found out the MUD had a charge running through it from the power lines.
Instead of shorting a capacitor out to discharge it, use a 20K to 50K, 10 watt resistor across the cap terminals and it will slowly and safely discharge the cap in a few minutes. Remember once a cap is discharges and you remove the short, the cap may very well regain a charge over time. So leave the resistor attached to the cap when not in use.
I used to work on gen powered light carts. eventually the capacitors would begin to fail, at that point the lights go out and come back on in about 12 minutes after the capacitor recharged. If you leave them set for long periods even a bad capacitor would recharge on it's own. the world is full of free-floating energy, such a mystical force. Nikola Tesla's playground.....
as a retired telephone linesman, I've dealt with EMF many times and to all kinds of degrees.The worst was when I was placing a temporary aerial cable under a large transmission line.I was in bucket, and blue spark started jumping between different metal parts of the bucket. I came down and grounded my truck, Still sparks jumping. I ended up finishing the job with hi voltage rubber gloves on, as I couldn't touch anything without getting zipped.
Years ago,I had a customer that was fed by type C rural wire, with the 14ga hardened steel conductors, it was hung on a transmission line on wooden poles, following an ice storm one side went open, and we had a helluva time measuring the open because it induced something like 130 volts AC, and because it crossed a highway ramp it was stupid high, so a regular bucket wouldn't reach, they ended up hanging a 6m strand and lashed a 6 pair drop to it because it was way too far between poles for self supporting drop. In retrospect, I should have had them lash up 2-19 Gopher wire, so we could have bonded and grounded the shielding, would have really reduced the FEMF and power influence.
Rural "c" was the worst for EMF pick up. I was stripping some one day to lay down in 5502, by my belly. It jumped arch blue spark onto my belly, and thru my shirt. Burned me and a hole in my shirt. I'd have to ground the wire, and I'd have about 20 seconds before another charge would hit. Another time on an ice storm, 4 guys were picking up some 109 for me on the pole. They picked it up, and all 4 knocked to ground with arch between wire and ground. Again for me to "tie" in the wire on the insulator, I had to ground it out and quickly tie onto insulator. We initially thought we had a primary wire laying on our wire.... but we drove the area a mile or so in each direction ..... no primary. Just EMF.
i parked my truck & small enclosed trailer under some lines at an offroad area a few years ago, got back from riding, the trailer had become mildly energized, gave me slight shock when i went to open the door.
You can get significant induction voltages from much less than 230kv if you are close enough! I first figured that about 20 years ago while waiting for a train. It was a rainy day, so I had my umbrella up. I was stood on the platform and kept feeling this zapping sensation in my right hand and a faint buzzing noise. I looked up and there were little sparks around the spokes of my umbrella and as I adjusted my grip so as to only hold the plastic handle there was visible arcing about 4-5mm onto my hand. 😵 I was amazed! This was coming from the 25kv traction supply lines about 8ft above my head.
Back in the 70s my friends and I discovered an odd phenomenon. If we were barefoot and touched an unpainted spot on the house gutter downspout with our finger nail we got a mild shock. But only sometimes. Then we figured it out. The guttering was galvanized steel. If it rained, any dead leaves in the gutter would produce a mild acid and turn the gutter into a battery.
Funny you should mention acid inside of metal things. I cooked pork chops with apple sauce in a cast iron skillet. I had added garlic and onions and the garlic turned a bluish green color. That didn't deter me from eating it. I turned the (electric) stove off and used a digital thermometer to check the temp of the pork chops. They were done, but still piping hot, so I left them on the stove to cool off. I go back and check the temp, again and a huge spark happened, killing my thermometer. I thought maybe the stove had a short and called maintenance to look at it. They found nothing wrong with the stove. The best I can guess is I somehow created a capacitor and discharged it with the second temp check. I still ate the pork chops.
Here's a neat test to try as we, myself and two fellow electricians in the mid 80's did. We grabbed 8' T-12 fluorescent lamps and wrapped the one end of them with aluminum foil. Then we held them in our hands straight up under similar 230kv transmission lines. They lit up like they were in fixture.
Back in the 90's I was doing work at a Navy VLF radio station. They offered us a tour of the radio house. When they went to show us the cables running out to the antenna array, they just grabbed a fluorescent tube lamp off of a bracket, and as soon as they held it the tube lit up. The cables were running in a large closet that went underground.
This was a Navy prank for any newbies aboard the ship, too. A saltier sailor would summon the new kids out to 'reset the phosphors' in the florescent lights, which meant dismounting the tubes from whatever lights were handy and bringing them out onto the forward deck. The prankster would demonstrate the proper way to 'reset the phosphors' by lifting the tube overhead and giving it a good shake - and a friend up on the bridge would turn on the radar.
No need to wrap them in anything....They'll light up underneath a 10KV line already....Just pick 'm up and hold above your head, in the rough direction of the lines....
Back last week, I went into my garage, replaced the fluorescent lamps in my fixture, then flipped the switch on. They lit up as if they were turned on. It was beyond amazing. Then I took the old lamps and threw them into the ocean for the dolphins to snack on.
I remember back in the 70’s a farmer ran lines under power lines on his property and the power company sued him for stealing power. The FARMER WON and powers part of his place with the electricity that’s lost to the atmosphere.
@@acinfla9615 The guy that had a wire coil in his attic? (I know we all are trying to remember something from 40 years ago). I think I remember he was indeed fined.
@@Tore_Lund That’s how I remember it. I think they tried to fine him or bill him for stealing power. I can’t remember but he got away with it for a while.
Buddy of mine owns farmland under some transmission lines. His dad built 3 barns right along the rightaway with giant coils of copper water line in the lofts and a bit of power conditioning hardware, and he sold power back to the grid out of their own lines for about 20 years before they figured it out.
Inductive resonance is a real thing and can be tapped. I found this out building solar powered electric fencing in Oklahoma. Those powerlines play hell with the control boards in fencing and we found out that we didn't need to power them up if the fence ran under those lines. Free electric fence power.....enough to deter horses and cows from going though. For fun walk underneath a high tension line with a fluorescent tube and hold it over your head in the dark. Free lighting !
@@heeeyno cicruit which can resonate. There is no thing as "inductive resonance", nor "capacitive resonance" nor "resistive resonamce". There is capacitance, there is iductance there is resonance. Separate terms. If you say "inductive resonance" I will not be taking your story seriously. You cant just make up terms. They are already made up. So everything else is INCORRECT.
I work for an electrical utility. I was recently installing new equipment under the overhead lines while working on an insulated fiberglass ladder. I had one lead from my volt-meter to ground while holding the other lead and the induced electricity into me would go up about 125 volts per step on the ladder. It was interesting to see the constant bug zapper action arcing when I held the lead about 1/8th inch from the grounded building next to me.
I work in substations and when i was a maintenance electrician I would climb the A frame towers. On a 220Kv line the induce was so great that i was able to write my name into the A frame with my finger, well for a little bit. I found holding a screwdriver hurry less.😆 Have a good one, stay safe!
Yes. As long as you are holding the conductor (Screwdriver) you won't feel it. Let your finger touch it and ouch. I was removing the sealant from a pass through to install wiring into the building and I thought that I was disturbing a wasp in there at first when I heard the buzzing noise. @@mmi6280
About 30 years ago was the first time I became aware of what happens in the vicinity of these towers. A very experienced horse breeder friend of mine married a man that had similar electrical lines running across a back pasture on his property. The marriage saw her move her 10-12 brood mares to his ranch where they were pastured in the same areas with the power lines. I understand that he had always used that area as hay fields, never having run livestock there for any appreciable time. Her brood stock included several older mares, each having produced strong healthy foals for many years. Within the first year some of these mares began experiencing miscarriages or still-births. Like I said, she was very experienced and kept meticulous records of every aspect of her operation. They finally narrowed the cause down to their prolonged proximity to those transmission lines. They moved the herd and never had that problem again.😐
I grew up near a field with some massive lines cutting through the middle, and i would pass through that field all the time. Being a kid, shorter of course, eyes closer to the ground, i started noticing how many 4 leaf clovers i would find under the lines. Then the more i looked, the more leaves i found. well as a kid i didn't know how unheard of this was but seriously, i found some clovers with up to 7 leaves. I wish i pressed some in books or took pictures, because i could find these things within a minute of looking for them, they were all over. But that was back in the 80s, they've since replaced the old giant wooden poles with metal ones, who knows what else they might have changed. I still go back there to look sometimes but i don't find them anymore. Oh and... yes they were clover. in case anyone thinks I'm full of it. The *other* 7 leaf plants grew on this neighbors property, which i didn't dare get too close to. But, If you do a search right now for 7 leaf clover you'll see pictures of them. They are supposed to be extremely rare.
I've heard the same story from a local farmer, lots of problems from the cattle herd with transmission lines going through thier pasture, they also fed hay directly under the lines because that's where the gate was located. All other herds were fine, same genetics etc.
I have seen the same 4, 5, 6 and 7 leaf clovers when i was a child, I think the reason here was actually the Chernobyl powerplant dust that fell all over eastern Europe. I am Bulgarian by the way. I barely find 4 leaf clovers now. @@derealized797
I was hunting near some big power lines here in Ontario. I was riding my ATV directly under the power lines. I was getting small sharp shocks on a constant basis through my brake levers. I was thinking the power lines had broken and fallen somewhere down the line. Apparently this happens all the time. Very cool.
Same thing happened to me on my dirtbike when I stopped to clear my goggles because it started to rain. I thought the rain was becoming conductive. Scared the living shivves outs of me and I throttled away at full speed!
When I was a land surveyor, if we would park our work truck under power lines like these, our truck would shock you... We had an aluminum camper top gimmick on the trucks, if you landed on it, both your elbows would have burn lines on them... I know all about that stray current...! Thanks for sharing... Keep up your awesomeness...
Weird coincidence but I worked for a seismic survey crew and did the same thing. I just crawled out of a swamp, soaking wet and went to place my pin flags into the back of the pickup truck. As soon as the underside of my arm touched the truck I got a very noticeable zap. The rest of the crew laughed when I squealed and didn't believe me but nobody would touch the truck. Also, this was back in the day when we had to use the time cube and do sun shots. They have GPS now, spoiled babies.
As a kid our neighbor would walk under similar transmission lines holding a fluorescent light tube over his head. Sometimes it would flicker, sometimes it would really light up. Forgot all about it until I saw your video. Thanks.
*If he would have hammered a long copper ground-rod into the earth and touched one end of the light tube to the ground rod it would have stayed lit to this day! Establishing a GROUND CONNECTION is critical!!*
We used to do that as a party trick in high school. Desk lamp fluorescent tube with light right up when held above our heads while standing under the HV lines in the neighborhood.
A length of insulated hookup wire would be cheaper than coax. I would expect a larger power draw if you moved your pickup wire further away from the lines (up to a point) because the wires are carrying 3-phase and the fields cancel to some degree the closer you move to the centre - they won't cancel completely because the wires are physically separated but field cancellation is what the power company would like to happen. The idea is to couple more closely to just one of the wires to reduce the field cancellation effect (make one field stronger than the other two which in effect moves you closer to a single phase pickup). If you want a decent current, a large loop with one side as close to one of the outer lines as possible and the opposite side of the loop well away would help. This gives a single turn transformer secondary with one of four sides coupled as strongly as possible with two sides not coupled at all and the fourth ideally low-to-no coupling.
In the early '80s, my friends house had powerlines just like that going over their house. The rain gutters and down spouts had a significant electrical charge. Us neighborhood kids loved pushing each other into them or better yet, tricking anyone that didn't know better into zapping themselves. It was strong enough to arc off any grass or weeds that touched the downspouts.
a lack of earthing to your gutters/spouts/plumbing . An electrically 'floating' conductive surface..... it is best to ground them in general. Then you don't get zapped.
As a kid,mom had a fridge that would shock us when we grabbed the handle to open it. I was a hero when I got a job ,went to Sears,and bought mom a new Kenmore refrigerator. I think I was a good boy...lol....
AC Induction is very common on a long parallel run of metallic cables. I work in the telecommunication industry for over 20yrs and we have to mitigate these induced voltages. Normally we use AC Chokes to flip the phase 180°. This counters the induced voltages. However, there is a saturation point where the the the AC Choke can be over run and the effects become null. Generally, these voltages does not produce high currents, but still can give you a healthy jolt. If you ever heard a 60Hz hum on a Plain Old Telephone Service (POTS) line, then you know why now.
An afterthought to my earlier post. In the late 1970's I owned a cablevision system. Our main trunk line to town from our headend on a mountain was 18 miles long. It was buried along a highway, underneath high voltage electric lines. Each of the 36 amplifiers on the trunk line operated on 60 volts AC, which was duplexed onto the cablevision line, along with the TV and FM channels. We had power supplies every mile or so, which injected 60 volts into the cablevision line, and the further you got from a power supply, the lower the voltage. At around 38 volts we'd install another power supply - and back up to 60 volts again. But amplifiers kept blowing. I mean, like burned up. Since the amps were in underground volts we were perplexed, since they were secure from grass fires. So out with the voltmeter. Surprisingly, we had between 100 and 400 volts on the line - despite putting only 60 volts into the thing to start with. We went through one hell of a lot of amplifiers before we finally figured out that we were getting inductive voltage from the overhead power line! At first we added light bulbs to each amplifier, which glowed brightly and scared traffic. And they would glow bright or dim, as the current load on the overhead wires varied from time time time. Finally, our engineer came up with a fix. A 'crowbar' which used an SCR diode that would short to ground any voltage over 63 volts. So the power line induced voltage would be bled off to ground. Those diodes would get hot like an electric stove element, to the point where we had to heat sink them to stop them from burning out - that's how much power we were getting from the power line induction.
Damn 36 amps, that's must've been a hell though, back in the day you really only had to care about C/N, unlike today where you have US (for modems) too.
@@twohullsThis wouldn't happen with underground power lines because they have a grounded shield. That's because people and other objects could be very close to them, and the other phases are buried together, rather than digging three trenches, and you don't want them to couple.
Friend of ours back in the 70's built a new tie stall dairy barn for his registered Holstein herd. High tension lines on steel towers ran about 400 ft behind his barn. When he got the florescent lights hooked up and they turned them off they didn't turn off! Over the years they installed florescent lights in several other buildings with the same results. As far as I know they still work today.
@@somethinburnin I believe so but honestly cannot tell you, didn't pay that close of attention plus I haven't been past there in over 10 years, They're about an hour drive from here
Back in the 80's we ran a permanent electric fence around a large farm I was working for. Part of that fence ran under some large power lines coming from a power plant and once that fence was insulated it was hot without being connected to a charger. This fence was 5ft tall with 6 lines and fiberglass posts and the lines alternated between hot and ground, They were all hot under the large power lines.
Sounds like you were wasting free electricity. You should have set up a large scale version of what was shown in this video, and powered your electric fence for $0.00.
so how about legalities there then. if the power company claims that drawing on that magnetic field is stealing their power then it must work the other way round: if they, so to speak, 'push' their power into your fence with all concomitant possible dangers and inconveniences then they should be liable for that. right? quid pro quo.
@@abrogard142 That's assuming the power company would notice, let along care, that he was capturing power leaking from the lines. Right now this phenomenon isn't large enough for there to be a standardized ruling one way or the other. It very well may be that even if the power company does accuse him of stealing power, he could take this case to trial *and win* thus negating that possibility altogether.
Very interesting experiment! During the time the cap was charging from 186V to 331V, the average current was 0.19 milliamps. [ i=C x delta(v)/delta(t) ] This raw current at the open end of the wire will not kill you but the capacitor itself can deliver enough current to be dangerous. I would wear gloves around this circuit. A comment below mentions how HV lines affected horses. I've heard of other cases when HV affected cows and horses. Their feet are always touching the ground and an AC current flows through their body.
not related to power lines, but the NEC has rules for grounding structures for dairy farming. Apparently the smallest of currents traveling through the cows feet will sour the milk, making it undeniable.
@@G8tr1522 Or maybe it's because the fences and guardrails are all metal and in some places you have electrical equipment in contact with it. A colleague of mine managed to kill 10 cows in the milking parlour because he forgot to ground the milk pump and when on the third day of testing the farmer managed to flood it a current of about 40ma was flowing from the pump's chassis through the stainless steel pipes to the metal guiderails for positioning of the cows for milking. The structure was also not grounded and the cows were grounding it out trough the wet concrete floor. Turns out cows are very sensitive to 50Hz currents because all 10 in the parlour dropped dead from that.
Have you noticed how guardrails always screw up someone's body current and tend to get hit alot? Gophers follow my fence lines and drip irrigation to the free food buffet.@@TheOriginalEviltech
In a physics class I took a few years back one of the exercises was calculating the windings needed to power a house from the EMF coming off a high power line. Then the final question in the exercise was : "is it ethical?" Well I'd love to give it a try and see how long it took for them to find me out! :D - EDIT - FYI - The power companies monitor the lines for leakage. Building a system large enough to power anything substantial would show up on their test and found out. It would be considered stealing. I hope this puts an end to this conversation.....
@@rogerhargreaves2272 Well it depends on how ethical you think stealing power is. You're setting up an inductor under the power lines that's not free energy, anymore than bypassing your electricity metre is. If you find a water tank, that isn't yours, but the water is slowly evaporating off, is lighting a fire under the tank and then condensing the steam not stealing the water? It's not "lost" energy that's being recovered, the the transmission losses are LOST, much like how the naturally evaporating water is lost. Putting an inductor under the power lines is equivalent to lighting a fire and boiling more water off. It's just hiding theft in a way where it appears to just be extra natural losses (until someone finds out at least). Think about an electric tooth brush or at least its charging unit. When the tooth brush isn't on the charging unit, the unit still has AC running through it but it's just resonating back and forth, very little is coupled to the magnetic field it's generating, so that magnetic field is just wobbling back and forth, constantly taking energy but also putting it back into the mains (actually an idling toothbrush unit is way worse for loses than the above, because the above will have capacitors tuned to put the energy back in at the right phase at the substations). The dominant losses in the toothbrush situation are due to a small amount of resistance in the coil that the AC is running through. When you put the brush on the unit though, all of a sudden that magnetic field is driving a coil in the brush, inducing a current in the brush to charge the battery in the brush. The unit isn't making free energy, it's just now being transferred from the mains driven charging unit to the brushes battery. So make no mistake, it is NOT free energy. Every Joule taken is an extra Joule the electricity provider has to generate in addition to the natural losses they have with transmission system. So the real question is stealing a few milliWatts ok? Personally, if it wasn't silly amounts of power (i.e. powering your home, though that'd be a lot cheaper and safer to just rig the electricity metre) I probably wouldn't tell anyone.
My last final exam question was in environmental engineering. I had to determine how long a fish could live when certain chemicals were introduced into its bowl. I answered the fish died from jumping out of the bowl when the chemicals were released. He dropped me from a B to C on final grade!
I'd say that it's free electricity because it's in the air. Would never notice you collecting electricity, because there'd be no loss on their end. Maybe if they were doing maintenance and stumbled onto it, but it's still not illegal. Think of it like using an air compressor. You can't be charged for the air that is all around, although I'm sure that the J P Morgan's of the world would love figure out away to make money from free air use.
We had a small fire in a combine a couple of years ago that disabled the combine. We pulled it out of the field and not really thinking anything about it, parked it underneath some high tension power lines. The header of the combine was sitting on the ground. Later when we climbed up on the combine to work on it we kept getting shocked. That made me believe what you are doing 100%
A great example of an air core transformer. You will get more induction by reducing the separation between primary and secondary, and increasing the length in parallel. Changing the angle between primary and secondary reduces the (effective) parallel length, which reduces the induction.
Looks like capacitive coupling since he's just connecting to one end of the wire. If he went to one side (to couple better to a single phase) and had a larger 'plate' i.e. more wire, he'd probably get more out of it.
You may get better results not using a coax cable being that the core you are hooking up to is shielded. ground the woven metal shielding to the copper on one end. that will utilize the mesh in the induction process.
And coil the secondary for increased inductance. I was watching this and wondering what the result would be if you stretched out a toy slinky and performed the same test.
I suspect a sheet of aluminium foil, or a vehicle, or any other large, flat conductive object would work very well as a capacitor plate. Put it high up, and I'm guessing directly under one of the outer phases will be optimal but experimentation will tell.
On the farm I grew up on, there is a 120,000 volt transmission line. One portion is 1/2 mile. My dad said ... years ago, before steel fence posts were common, (the posts were wood) that 5 wire fence (between his and a neighbor's field) would have an 'induced' current in the top 2 or 3 wires.... enough to receive a "Dirty Shock".
I used to bicycle past a farm property with HV lines over it, I got shocked from contact with my own bike frame and used to see arcs between the fence wires and the ground.
I have my metal roof grounded within 20 foot of highpower lines. The emf measures at 120 or higher in my addition, so metal siding will be used there, 0 to 8 in the current house also 0 directly under the lines. ?.
@@HarleySeaman-p9h "EMF" is very broad and relative. It is a huge range of frequency, some of which are constant & universal, and some which might be more interactive with matter. But then also, 120 might be 300 on a different meter. It is an absolutely relative measurement.
0@@Observer_Effect I know the gophers follow the metal farm fence and the drip irrigation lines, tend to munch the roots along the line. I now have a dog and cat that will dig them up and enjoy a little extra protein, My meter is Erick Hill RT 100. Thanks, always willing to learn more. I had beets and turnips with the drip lines larger than I had ever see.
I've done some experimenting in this area too. This is capacitive coupling through the air between your wire and the power lines, so you have to use a full-wave rectifier as you are, otherwise the 'air' capacitor simply charges, and you get no power. This setup works to a lesser degree even under 14.4 kV distribution lines. You were likely pushing those diodes near their limit, because when reverse-biased, you have the capacitor voltage plus the peak source voltage in the opposite polarity across them. Of course this is divided across 2 diodes in the full wave rectifier.
Thank you sir for your efforts, in both braving the cold and the testing. I am in Wisconsin and it's -9 this morning so I know what your dealing with in that regard. As to your test and charging your capacitor I am not surprised of the amount of passive power you captured. Depending on the transmission flow rate in the wires, the equation for radiated power would show that a capacitor several times your 1200 volt rating could be charged (given the bridge rectifier having diodes of sufficient rating to handle the load. Excellent job and very informative enjoy you very much.
🔌🔌In 1977 I worked in a utility transmission department as a COOP Electrical Engineer in southwestern Michigan that had 765kV power lines from the nuclear plant. An individual claimed that a fence caused a spark in his tractor. Sure enough, we found out that this could happen and caused a change in easements setbacks. We also tested 69 and 230kV. 765kV was much more likely to spark. Also, the blowing sandunes caused the land-to-plow line clareances to change drastically.🔌🔌

All their data center locations have a high level of security. The next nuclear plant under design is Bill Gates's TerraPower in Wyoming. It will not be used to power any Microsoft facilities. Azure(Microsoft) data center has talked about a small nuclear reactor(SMR) plant but it will most likely not be in North America and will be many years away.
I remember us having to dig an underground ground grid. and place ground rods down all over and ground cables all tied together to keep the induction down.
Great video! You might try coiling wire into plastic barrels to see what effect you get. About 25 years ago there was a fella here in Phx who was gathering enough of the power leaking out of the HV lines that ran across the back of his yard that he was running his house on it for free. When the power co. found out what he was doing they were big mad, but the cops & court said he was breaking no laws so they had to leave him alone!
I've heard about this phenomenon back in the 90s. But they referred to it as "stray voltage" and tell you stories about cattle getting electrocuted, and homes that were next to lines would have all kinds of problems, as well as the occupants coming down with weird illnesses and cancers.
I believe there was a huge lawsuit in Iowa maybe fifty years ago over this issue. The farmers were trying to prevent being forced to have these power lines cross their land, sometimes very close to a house or barn.
Years ago I read about links between high power lines and what medical researches called 'cancer clusters' which were the people, mainly children, who lived in low cost housing built near to the lines having significantly higher levels of several types of cancer. The power companies were not found liable however those people in the lawsuit were offered alternate housing away from the power lines out of the kindness of the companies heart.
@@bendover1028There is exactly zero peer reviewed research that shows anything of the sort. None. Nothing. There is no physical way that non-ionizing radiation can possibly cause such damage.
I was a line clearance worker, aka Tree man, for a power company. We parked our trucks inside an electrical substation. You could feel the hair on your arms reacting to the energy in the air. O.S.H.A says on a simgle phase primary line(7,200kva) you must maintain 2 foot 10 inches or the electricity can/will ark/ jump to the ground source (you) 🖖✌️👍
Personally I hated having to go anywhere near HV lines or substations.. Had to repair some equipment at one and the warning signs said 15 ft. It was foggy, security guy said ignore signs and try to stay at least 5ft away from the security fence, (20 +ft from any HV equipment) the warning was only good in sunny weather!
I am 79 years old and 50 years ago I had a girlfriend also now in her eighties who contracted the dreaded MS disease. She lived very close to powerlines and some scientists wondered if powerlines were the cause of this and other illnesses. Your experiment just shows what is radiated from these lines and possibly affects millions of others. This lady, badly crippled has lived in a nursing home since 1990 bless her. I think that there is a massive cover up of the hidden damage done by radiation such as this and I am glad that you have highlighted it. Well done. B
if power lines cause disease, why don't microwave ovens? Short answer: non-ionizing radiation is not the same as ionizing radiation (WHAT A SHOCKER!!) also, power lines don't cause disease. Stop with this nonsense.
Well, it shows energy is radiated, but not that it causes problems. Remember it's taking miles of metal fence to pick up this energy. And if the fence was connected to ground, it wouldn't be detectable.
In the 70s many farmers property were threatened to be taken be eminent domain If we didn't give the power company an easement to put a high kv power line in. Farmers relented and in a couple years the cancer rate along the power line increased dramatically. 't
My sister-in-law used to live near overhead powerlines, the big ones with the tall scaffolding towers, right behind her house. Her daughter was born during that time and developed Non-Hodgekins Lymphoma, or blood cancer, if you will. We've wondered if growing up in close proximity of high tension power lines caused or contributed to this. It's not uncommon for people living near power lines to experience health issues.
I know next to nothing about electronics. As a retired HVAC service technician, I was cringing while waiting for the capacitor to exploded. In my years of servicing air conditioning equipment, I replaced many run caps that had exploded. Glad yours didn’t.
I was in a radio/tv repair class in high school. We would hook small electrolytic capacitors up to a power supply and crank it up until they popped like a fire cracker.
@@youtopia2000we used to charge them up and toss them to people that didn’t know what caps were. It was a fun little prank to zap people when they caught the caps we tossed to them. 😂😂✌️
Those 1000 volts diodes change AC to DC. It takes 4 diodes to capture all of the sine wave the fence wire pick up. You can use one diode but it will only capture half the sine wave.
Retired land surveyor. Whenever we surveyed under hi tension lines and set up the transit you could feel that it was energized because it would 'bite' when you touched it and if you grabbed hold of it it would 'buzz' in your hands.
Kreosan did this but they also used a transformer (it might have been a car ignition coil or perhaps a TV fly-back transformer). They had a rectifier of course, but also some kind of voltage regulator. With this setup they could harvest enough energy to charge a cell phone with the antenna just being a one meter whip and the ground the frame of one of their bikes. The lines they were under though were the big ones, maybe 500KV.
@@davidca96 I've never worked on hardline. Just RG6 & 11. It's only been a few times where I brush up my arm against a drop while it's disconnected from the splitter. But I've only been on the cable side for a few years. Did telco for 17 before that, which only has -48 DC idle, but ringing is 90 AC which definitely gives a good zap!
@@grabasandwich Ahh ok, I am a network maintainence tech myself, been in the business for 23 years. It sure does wake you up especially if your gloves are wet haha.
I worked for a local municipality as an operator of a TV inspection truck. This truck was used to inspect the interior of pipe using a CCTV camera. The spool of cable it used to connect the camera to the rig was over 500FT long, and coiled-up on a 4ft diameter spool. One job assignment had us inspecting a storm drain under a 240KV transmission line... It knocked two of us down stepping back onto the truck after hooking up the camera to that cable. EMS was called, and it finally dawned on me WHY we got shocked. I got 480VAC between the rebar of the catch basin and the frame of the truck. SHOCKING, huh?!
The same thing holds true for shunt fed and broadcast towers. I used to manage a tower facility in the Northeast that was adjacent to a school and had a chain link fence around it. Every time I would bring my key up to the lock it would draw an arc because the fence was electrically hot due to the RF field and the highly reactive antenna.
If its your land, and they aint paying rent, then Id say it was ethical. (They control and restrict your use of the land under the lines) Just my opinion.
@@harrypitts7389 failing radials can be fatal for transmitter sites. 25 years ago, I was CE for a AM directional along the coast. 16 acre plot with two towers. Owner was more interested in leasing space to cellulars, than in maintaining the field free of growth. I warned the owner multiple times about the roots severing ground radials but he continued to ignore. Years later, one morning, I get a call. Station went off the air during pattern switch. I drive the 3 hours to get there and notice smoked coming from the building's vents. I open door cautiously and step aside. Smoke pours out of door. Waited ten minutes then rushed in and turned the thermostat for the ventilation fan down so it would turn on. Ran outside and waited another ten minutes. Once the smoke was cleared, I went inside and observed the damage. The Harris SX5 has totally melted down. The contactor that did the switching was in the top of the SX5. It's insulators were made of some sort of fiberglass/waxy paraffin material, and when the contactor drew an arc, the arc sustained and caused the waxy materials to ignite, dripping down flaming debris into the lower part of the transmitter. It was a total write-off. I didn't want to tell the owner "told ya so!", but I think he knew.
They didn't say how high you could build the fence. Closer the better. You would still have to regulate it somehow. Interesting. I've heard about this being done and always wondered what kind of practical coupling occurs. Thanks for taking the time to experiment and share results.
There's a historic railroad SMRS IN Michigan USA that one of the volunteers was an elect engineer. He became perplexed about an 1890 railroad bridge not rusting hardly any. Checking metal composition possibilities and anything he could think of couldn't figure why. One day I told him why I thought it was natural magnetism since the rails went mostly north/south and not having rail traffic much of the year it induced a small anti corrosive charge. He said didn't think of that and would explain whole thing.
You tested e-field pickup. You might get more power from residual magnetic pickup, and the voltage would be safer - you can run a 'fence' wire along the ground under one of the outer lines, and a return line a few meters away from the power line. This should be a much lower voltage around your loop and might be a useful amount of current. You might also find it is mostly 180Hz (third harmonic) due to most of the 3-line 60Hz cancelling itself out!
Yeah - is it the dielectric field that would be captured ? I would not think there would be huge current and huge magnetism being transmitted but the electric field would be enormous - and what of the 'theft' issue ? does pulling field off deprive the field ? or is the field just wasted emissions ? my guess is "B" so no theft
Cool. I was thinking on the same lines as you. No pun intended. Can you imagine the size of the magnetic field and it's density around that heavy conduit carrying how much voltage??? Yeah. I'd be abliged to " experiment in ignorance " what I could do with that magnetic field. 😊 I use aether sticks in my garden pots. Thy utilize the free magnetic energy around us. Magnitizing the soil that plants really enjoy. It also helps detour subterranean insects that thrive on the roots of your food, and many common ones that feed on the leaves and stalks. They don't like the the frequency. 😊 But the plant sure does.😮
LOL you should put a disclaimer on this. Kids all over the country now are going to be doing this! Thanks for sharing. Best Wishes & Blessings. Keith Noneya
Power company: "There is no health safety issue with overhead power lines." Same power company: "Hey, you can't use power from the air. That's our power!"
Are you worried about health safety issues with the electicity in your home? You can do the same thing in your house, or more to the point your neightbor could do the same thing with your utlity hook up. Would you be ok with you neighbor "harvesting" 100kwh from you?
It's the amount of power and the distance from the wires that matters. Sure, I can do the same thing in my home, right next to the wiring in my walls. This guy is doing it at distances greater than the width of my property, and getting more power! So no, I'm not worried about the power in my home, but yes, I am worried about high tension lines. I also don't like the fact that power companies get government support to maintain and repair them. It was their choice to put them up high instead of burying them, and it's their equipment. Let them deal with the consequences.
Put insulators on your barbed wire fence and your stealing.... get the piss shoked out of you for touching a barbed wire on a wood post on a dry day and thats YOUR PROBLEM!!! I Get it now!
Caution, you can accumulate enough induced voltage in your “fence” wire alone to stop your heart (1 - 4 amps). I’ve lost a co-worker to very similar conditions. Don’t experiment and loose your life.
It only takes about 20 - 40 milliamps to cause fibrillation. The higher amperage is actually better, since it will stop the heart - meaning it is easier to restart.
You should put a 50K resistor and amp meter across the positive and negative leads to see how much the voltage might drop to. To measure the resulting current and see the usable DC voltage available. Maybe see if it could power some LED Christmas lights. :)
About 45 years ago, a friend of mine bought a small parcel of land from his family farm, and built a house on it. There was a set of high-tension electrical transmission line along one border of his land where was was a disused stretch of barbed-wire fencing. You could definitely get a pretty good jolt off of that fence.
You can walk under them with a long florescent tube and it will light up . We used to tape a small one on our radio antennas key the microphone and they lit up from the RF. Same if you pulled into a gas station with tubes under the canopy touch them with a 1/4 wave 10 meter whip and you could light them up all the ways around the station .
Wow! What an interesting experiment, and the comments below are just as interesting. Anyone can see clearly what is going on here, which we should all be aware of. Many times, I have walked areas where these run through because the easement makes it easy to walk through, like national parks and other areas, it is kept mowed down and, on a hill, it is easy to see long distances. So, that amount of energy is below and in surrounding area all the time! It does affect living things..... and could cause some issues I would think! Thank you for this video, it is very amazing! I am going to share and put it in my community spot so others can see too (if anyone looks). Thank you so much and You stay safe!
Your DC voltage will be 141% of the AC voltage in the Coax. DC wont inductively couple as well but it doesnt transmit over distances well either. Get a Fluke meter and the Fluke 40,000 volt probe. We had to run autotransformers buck transformers on large multifamily residential jobs so we had 120 volts at the end of 300 to 500 feet of extension cord. Otherwise we burned up our power tools. We'd tap off at 152 volts and sometimes only had 110 at the end of the cords. You cant help but lose power over distances.
You could put a step down transformer on the end of your coax wire, that would decrease the voltage to your bridge rectifier, but it will increase your amperage to a usable amount, that you could run a burried insulated cable, to your house, to keep a battery bank charged to help you reduce your electric bill. 😁👍

Good video on describing lines of flux called the left hand rule. The lines off flux coming off the high voltage lines is pretty significant. Higher the voltage, the larger the lines of flux. The RF cable you are capturing the voltage is pretty cool but use caution when doing this.
The higher the CURRENT, the higher the magnetic flux. The distribution network uses high voltage lines specifically to reduce the current and magnetic flux levels.
It’s really wild how much inductance is happening under those power lines I was on a transmission line building crew and it would charge the line we were building beside it to 29,000 volts and when we put the grounds on it would make at least a 6’ arc. We also had fun with the static from it. We would make little wire pistols and shock each other on the neck or behind the ear haha
A guy I went to school with built his house right under those power lines, the large ones with the steel triangle support tower. We studied electrical engineering, I thought he was nuts for doing that. Grand kid was born with all sorts of issues and didn't survive more than a few months. AC power is nothing too be fooled with or taken lightly, some engineers don't even realize that.
@@jedclampett3725 Spoke to people in a housing tract built underneath massive high voltage transmission lines, whilst canvasing for a sales job out in the backwoods of TX. The residents of that little housing tract had lost multiple members of various families to cancer and other ailments that could not be explained. A study had been done to find out why everyone was dying there, and the only common denominator was those high voltage lines. They were all convinced they were the culprit.
> . . . when we put the grounds on it would make at least a 6’ arc. < The dielectric strength of air is about 1,000 volts per millimeter, or 1,000,000 volts per meter. 6' is 1.5 meters so are you saying that you developed 1.5million volt arc?, and lived to tell about it? An arc of six inches in dry air corresponds to 150,000 volts, which is also courting death if there is any current at all behind it.
@@peteinwisconsin2496 Yet Tesla and Mark Twain played with that electricity in Tesla's lab all the time. I guess when you know what your doing, you can get away with doing dangerous stuff. Re: Dangers of AC power. Read "The body electric" by Robert O Becker the last chapter is how he tried to convince utilities to not use that frequency because of the harm it can cause. Tesla tried to warn them as well. They weren't having it. I guess it was intended to cause damage and feed the healthcare industries profits.
Thank you for creating this video. I've felt tingling when up around high voltage transmission lines. I didn't think it would be healthy to spend a lot of time around them, but I didn't come up with a method that would allow them to be shock dangerous unless touching them some how or coming close enough for them to arc. This experiment shows that it is conceivable that it is a possibility some type of configuration might emerge that could store energy and create a deadly charge. It would likely be some weird like some piece of equipment with a hidden high voltage compactor that somehow gets a conducting induction loop by chance created to it under a high voltage transmission line. It is in a trillions of a chance, but some association of junk under transmission line could have that happen. I'm surprised there is not more videos in the popular science/mechanics venue that bring up how much energy high voltage A.C. transmission lines loose through stray induction to their surroundings. Another characteristic would how much they loose by radio wave radiation. Typically I'd assume radio wave transmission loss of energy is close to zero, but not zero compared to the energy in the line.
It was when we could have gotten so far until the bowl fell breaking into many pieces so after that we decided to be more careful. */OR/* We were almost finished when the bowl fell and broke .We decided to be much more careful moving forward. see what I did there? your welcome.
We were working on a road to a radio antenna near a power generation plant. Not sure what the voltage was on the HV transmission lines, but I had parked my F350 crew cab long bed under the transmission lines perpendicular to the lines. Chrome door handles and I had a very hard time getting the door open to get in. Every time I touched the handle, it hit me like an electric fence.
I work for over 30 years for a utility and one of the problems in the high voltage switchyard is inducing a voltage in fences and handrails, even thou these things are grounded, you would get a shock. There is no current when this happens so no health problems but still a SHOCKER
Reminds me of the foxhole radios i made in my youth; Was always amazed that a small antenna pulled enough voltage from the air to run a piezo speaker earpiece.
I was an RF tech, we tested potential cell sites, and would use a bucket truck to hoist the antenna to the proposed height. To look both for potential coverage and obstacles, I would go up in the bucket and take pics on the 8 cardinal points to get a 360 view. One time we were proposing mounting to HV transmission lines, the SDG&E guy opened the gate and drove away, so we went about setting up. I was about 8 ft from the lines, in a metal framed bucket. My compass went nuts (actually reversed polarity) and as I reached for the controls I got BIT, not deadly, but I crossed my arms and had the driver lower me from the ground controls. Later talked to the SDG&E guy, who had no idea we were setting up, that close to the lines and said that would NEVER work, as it's inside the 'field' and it would fry the antennas! that compass still points south!
I worked for Hydro-Quebec. They used to remove the direct connection to ground of the "ground wire" and do it through lightning arresters. They would pickup the voltage from that line to power a remote substations.
As a pipeliner I’ve worked on many projects laying pipe , like 36” or 42” , along power line R.O.W. We have to ground every piece of pipe brought in just while laying there under those lines. Heck yeah they build charge !! Seriously no joke.
I knew a guy that pretty much powered his big barn and shop with big sono tubes wrapped in Romex, that he buried under the big power-lines that ran across a field behind the barn, his house was powered by panels. He was totally off the grid.
An acquaintance of my mis spent youth used to have a pneumatic -- It looked like a potato gun -- that fired a sabowed chain that would create a bolt of lightning upon striking transmission lines. He did it to a distro line in the evening once; no lightning but four blocks went dark. Crazy stuff.
I worked at a company called Genscape in Louisville Ky years ago. They sell reports about commodities to brokers and one of those reports was on what electricity was going where and who was selling electricity to whom based off of boxes they paid land owners to place next to high voltage power lines that measure how much electricity was going through the line based off the magnetic fields.
That's interesting, not the boxes, but the fact they totally bypass the power company and make their own measurements. Because the power company would already know this stuff but they don't want to ask them.
@@thewhitefalcon8539 It not a matter of willing to ask its a matter of the power company willing to release or quickly release. These commodity brokers trade on that info daily sometimes hourly. An example would be if Con-Edison has a problem with a plant and has to buy power from Duke Energy. The brokers would invest in Duke Energy supplies. It is big money. They use FLIR cameras on oil tanks like those at Cushing to provide oil stockpiles info to brokers. They use satellite phots to predict soy and corn yield for Ethanol production. Huge money in those reports.
My parents spoke of a city park in their home town in Germany where there was a park that had all the lights powered by overhead high tension lines. No wires to the lights, just a collector on top of the pole.
Back in the late '60s and early '70s, I tried to convince my Grandpa and Dad to let me put up a few loose coils of wire at the edge of the treeline and run them to a few lights along the horse path along one section of fence. This was back about 50 feet or so from the easement where the high tension towers ran. My Grandpa complained occasionally about being caught in the dark on that end of the farm and I figured putting up a light every 100 yards or so would provide enough to orient back to the house if caught out after dark. They were convinced the power company would come after them, but I couldn't convince them it was all loss for the power company anyway. The minor amount we'd get for a dozen light bulbs wouldn't even show, since it was loss anyway. It wasn't like I was going up a tower and hanging a coil up there. I always meant to run out with a coil of wire, a light, and a meter and see how much we could get, just to know, but never did.
I remember going up on the hills near where I stayed a few years back with a fluorescent tube. When I stood under the 400kV lines holding the tube vertically in my hand the tube lit up from the top of the tube down to wherever I held it. It wasn't super bright but that was due to the field created under the lines being capable of producing only a low charge flow through the insulating air and if instead I had erected a small wire array say 2m in the air and had electrically connected one end of the tube to it and hung it vertically down and earthed the bottom end of the tube to the ground it would be very bright and the brightness could be varied by raising and lowering the top wire array. You could have done that easily enough.
Many moons ago I was installing a new audio system in a strip club near the Rio in las vegas. After troubleshooting some noise and ground loop issues, I discovered the earth ground to be the main source of the various problems with that building. I was told by an engineer that the city has areas where this can be found and measured. These spots would also migrate around the valley. The dry desert ground and the high demand for electricity, mostly from the Casinos, being the reason for this.
Excellent practical demonstration - and cautionary tale. I was interested in the charge rate and wondered if I plotted the voltage vs time if it would show the expected exponential curve. (data for the curious: 2:04/0V, 2:36/180V, 3:45/328V, 4:38/423V, 5:10/478V, 5:37/515V. Stopped there because of the glove break.) It does initially but then the slope stays the same. Interesting. A friend of mine worked at SNC in Wisconsin. One of their products was a device (probably a common-mode choke) used in rural land-line telephone systems prevent phone techs from getting killed from just the thing you demonstrated. Think about the power in a phone line that runs close to and parallel to power lines for miles! Yikes!
@ethanlamoureux5306 it's not the case in my area. The pairs aren't shielded, they're twisted and don't even have a guard wire. Many of the copper pairs are within 4 meters of 33kv aerial lines.
@@dinosshed That may be true in some cases, altho I have only ever seen it on rather old, smaller cables with few pairs, such as a 6-pair drop. Bear in mind that when I say shielded, I don’t mean each individual pair is separately shielded, but rather the whole cable is normally protected by a corrugated metal shield just inside the outer jacket. This protects against physical damage as well as electrical interference. The oldest cables used lead jackets, and when they moved to polyethylene jackets, they also started using an internal shield to do the same job as the lead jacket.
@ethanlamoureux5306 I used to lead wipe the mains and repair the air leaks on them. Some of the aerial cables were shielded, but they were rarely joined with the strapping.
I used to install central vacuums. I was finishing an install at one particular house After all the connections were made, pipe and low volt electrical, I plugged in the main power cord. The motor came on as soon as I plugged it in. I thought I had miswired something. I went back thru all of my low voltage connections as it just sends 12-24v out to each outlet and if it comes back, it trips a relay for the motor. I couldn’t find any shorts in the lines. So I put a meter on the wires to check for continuity between them and had none. But why was the motor turning on with the low volt lines connected and not on with them disconnected? The only thing I could think at the time was a bad circuit board or maybe the radio station across the street had something to do with it. I went to the local RadioShack and picked up a power supply and a relay and got them temporarily going with the understanding that I would be back again once I figured out what was happening. After contacting the manufacturer of the system, they sent me a new circuit board and that fixed the issue. It turns out that they had ran into this before and it was indeed the radio station causing the issues. The low voltage wiring was acting as an antenna and picking up stray voltage that was triggering the onboard relay.
When looking for a new house, I was aware of the EMF surrounding high tension power lines. One of my stipulations was that the house be at least a quarter mile from any transmission lines. My extended family thought I was nuts...they built immediately adjacent to to transmission lines because the property was cheap. There are well documented effects of EMF and young people inducing lukemia. They have three young boys. God help them.
We bought adjacent to a 230kV line, and I didn't even check with a Gauss meter, but did have a plan. The house has aluminum siding. The second month here the steel roof went on. The window screens are now all aluminum. Five bars outside the (steel) front door. Zero in the living room and bed room. Not perfect, but the gardens are further from the HVL and I worry more now about just carrying the phone.
This works. We had HV lines running directly over the horse corral at a property we lived in a short time. I would take florescent bulbs out there and show people how they lit up just holding them up under the lines at night. But don't dare try to hook anything up, they will find that drain.
Many years ago I was setting light poles with a bucket truck in a parking lot. There was two maybe three, HV lines (systems) above, I can't remember. I was in the bucket operating the boom. I reached out to grab the pole to stabilize it and got a tingle. I told the guy down below, he though I was just blowing smoke. When he grabbed the bottom of the pole to center it on the light base he got a surprise. He took his lineman,s pliers and grabbed the ground wire from the feed wires and weld it close to the pole. there was a continuous arc. One of the guys ran to get some rubber gloves. It was all good once the pole was sitting on the base.
That one Pole was inducing more power to ground than I would need to run the lights in my shed. I'm rather surprised that the right of way allowed those poles to go up at all.
Back in the mid 70’s I was a Crane operator in Phoenix AZ. We were on a job North of Flagstaff in a small town called Grey Mountain. Arizona Public Service a power company was installing a large electrical transformer. In this business everything on the job including the crane is required to be grounded. As I was sitting in the cab of the crane the linemen were in the process of grounding the crane. We were located in an area similar to the power lines in the video….i looked down and to my surprise I noticed them laughing as by removing the ground wire that had been attached to my outrigger I could see them using a electrical arc to etch their initial’s in the paint of the crane.
What you aught to do now that you know it'll go over 1kV. Is to devise a small auto-discharger, which will drive across the gap of a neon / gas discharge lamp, such as a large street lighting luminaire, so that when you go back home, you can still se this contraption pulsing flashes every so often like a search light, especially if you aim it directly skywards (vertically orientated). Then if the power company ever complains, just tell them it's the automatic visual warning system, alerting you whenever the power goes out (by the lack of light) - to complain to them for not maintaining their own distribution services. After all, if you think they are losing power, consider how much "more" is being lost all along the length of that high voltage network, between their overhead wires and the ground (earth) below them, s 100% totally wasted power. It's just a fact, that these emf's will be generated all along the aerial cable routes, on any given day, right across the country, just a smidgeon - in the daily life of being a power operator.
Having been a crane Operator for the power company you can definitely build a charge by induction being close to power lines , and can be deadly if you are not very careful
Nice experiment¡. With 1KV reverse breakdown diodes you probably wont get much past that voltage on the charging DC capacitor. That's because the line voltages are alternating above and below ground potential (I agree with other comment in that there should be a mix of harmonics depending on the distance between the pick-up wire, witch doesn't need to be coax btw, and the HV lines in relation to the distance between the different HV conductors themselves). Anyway, because your DC capacitor terminals are ungrounded, usually the positive terminal will sit above ground potential and negative terminal will sit below ground potential. When the incoming or pick up wire picks a voltage of say 500V below ground, the diode of the rectifier that is connected between the positive terminal of the capacitor and the incoming pick up wire would get a reverse voltage of 1KV if the capacitor is charged to 1000V (Would help to see a diagram of connections and potentials referenced to ground). Conversely when pick up wire gets 500V above ground, the diode that is connected between the negative terminal of the capacitor and the pick up wire would get a reverse voltage of 1KV when the capacitor is charged to 1000V. Because of the relatively low current, the diodes would conduct in reverse without getting destroyed. The way to get higher voltages on the capacitor would be to connect the pickup wire to one terminal of the capacitor and the other terminal through a series of diodes to ground. That way you could reach n*1000 V on the DC capacitor, assuming that the cap has enough voltage rating and you use a series of n diodes rated at 1KV of reverse voltage. Of course you would get a half wave rectifier, so half the incoming current
= 0.077 watts. I looked up the power use of a common 5mm red LED, and find they use about 15-30 mA or about 0.05 - 0.1 watts at nominal LED voltage (3.2v). So I think he is pulling enough power to continually light a single 5mm LED, but definitely not at it's full brightness. I think this seems in line with the old school trick of standing fluorescent tubes straight up from the ground-- they will usually glow dimly if they are under HV lines. Seems like he will need a lot more conductor to pull any truly useful power.
@@gutrali Using field strength falloff it seems that his "fence" would have to be around 18.5 m (60'8") high to get 1 watt of continuous power with current length lol
@@ac281201 but 60 ft would be higher than he estimates the sagging lines are off the ground already. I think it would help if he created a cool rather than just a Rf antenna like he has here; no grounded far end
The power you can get from the fence is proportional to the current flowing (not voltage) of the transmission lines. So, sometimes you will get very little, sometimes you will get a lot more. I wonder if the 3 phases somehow cancel each other - would be interesting to setup a few "fences" with one right under the middle line, and the others a repeating distance apart moving away from the lines.
Field lines don't cancel, they change shape to accommodate a zero-flux boundary between the two opposing flux directions. With the 120* phase separation I'm not really sure what would happen with the flux and would quite honestly be a great simulation to run, seeing the distribution would sure help with designing a better secondary.
On lower voltage lines around the Pole Transformer getting 8000 volts ? - is there any sensitive meter that would detect current flows (producing magnetic fields) from below the line ? or would we need a clamp on meter to the HV line ? I was under the impression it was a dielectric field that was transmitting out - but I don't know enough.... to know
@@thewhitefalcon8539 if the current in each phase is equal they do cancel each other out. Cables are installed in tri-form to take advantage of the effect.
This has actually come up before. The way to actually harvest the power would involve placing a rectifier on each end and then collecting the power probably with shielded cable of some sort. The gizmo that does this is called a “rectenna”. (I Tryed to post a link but my phone isn’t cooperating. You can just search for the name though.) One little catch, you still have to pay for the power. 😕 When I say this has come up before I mean it’s come up in legal history. Power lost to unconnected conductors running parallel to the power lines is simply a loss that the power company has to eat. The moment you connect it to something you have “monetized” it. 🤷 That’s when the company in the business of selling the electricity gets a say in it. I feel like thus actually might be useful in areas without a normal tap but legally speaking it is something you do have to pay for. Interestingly this appears to be what Nicolas Tesla was referring to in his early work about wireless power transmission. It really isn’t practical for transmission of any amount of power for the equipment of his age but it might be useful now. LED lights have ratings of “something point something” watts. 😳 Well, maybe!
Nope, not how electricity works. The fence is being charged by induction and the power is sapping power from the electric grid. This will cause resistance in the power grid and the power company will need to supply additional power for this
Cool experiment. You should try putting your multimeter in Amperage mode, and put it in series with that circuit. I t would be interesting to see just how much current is flowing through that circuit.
Thanks for the post. As a lineman it’s always interesting to see people outside of the industry taking an interest in how our energy is delivered, most people don’t understand what goes into the generation,transmission and distribution process. Great work.What brand of hat are you wearing at the beginning of the video?
If you interrupted all the ground wires on a bunch of poles with a very tiny Gap and siphon the power from the wire connected to the wire that runs along the bottom when there be a whole lot of power coming out of that and hopefully the tiny Gap make it interfere with lightning protection. You may have to do it with a nice related set of polls like two of them and just have a wire strung right below it I think he might know what I mean as a lineman you could string an additional wire between two poles and connect them to something deciding off the power see what kind of results you get from that I think you would have a lot of power it's constantly running into the ground and that should be able to be siphon dog maybe the utility company could try that on a large scale and see if it's anything viable
It's not really the fault of "antiquated" infrastructure. When superconductivity is practical, efficiencies will increase. Whether the line was built in 1922 or 2024, present technology will be inefficient due to the (past and present) fundamental economics of transmission system design. Let's see what happens once we depart from ACAR, ACSR, HTLS and ACC conductors with significant corona losses. Superconductivity will hasten this advantage.
This comment was necessary to keep our humility. No real innovation here just skimming fat off a broken energy transfer system. Nicola Tesla, where art thou?
I have often wondered about this. However, your experiment needs to be expanded. Laying your fence across instead of in line either the path & adding several crossings. The lack of a load means you cannot measure current & therefore calculate power capability (Volts x Current). I always wanted to put a couple of turns around the base of a steel pylon to test this... It would be enough to run a cattle fencer, a repeater for ham radio, an LED light on a sign or driveway, or to charge or permanently maintain a small device or parked vehicle battery.
You're quite wrong about lack of load. The load was the charging of the capacitor itself. And during the approximately 480 seconds that he was charging the capacitor he collected 36.2 joules of energy. Another name for joule is watt second. So he was collecting energy at a rate of approximately 75 milliwatts.
@@johncochran8497 I agree with your method of calculation, but I see there was an interruption in the video at time 5:53. Up to that point, the energy collection rate (power) calculates as 55 milliwatts. After that, from time 6:03 to time 10:00 at the end of the measurement, the power calculates as 59 milliwatts. However, the actual power collected would be a little higher since the voltmeter, while it is briefly connected, draws power. That meter presumably has an input resistance of about 10 megohms or 11 megohms. Assuming 10 megohms, the meter consumes about 81 milliwatts at 900 volts. He was making brief connections. The voltage was definitely climbing in the periods when the meter was not connected. It seemed to also be climbing while the meter was connected at the end. If so, that would say he may have been collecting over 81 milliwatts in that configuration, but I can't tell if the meter was connected long enough then to be reliably responding to small changes.
@@analog_guy I failed to notice the cut at the point you mentioned, so that would mean that my calculation of 75 milliwatts was high. As for the parasitic draw caused by the meter, I would consider that to be extremely negligible. Although you should be a bit more careful about the difference between power and energy. If the meter was 10 megaohms, then I agree that at 900 volts, it would be consuming at a rate of 81 milliwatts. But assuming 5 seconds for the measurement, it would have consumed approximately 0.4 joules of energy. But there is the issue of the meter voltage reading actually increasing while the voltage was near 900V. That increasing value would imply that the power being supplied exceeded the drain caused by the meter, hence > 81 milliwatts. But the scene cut would imply that the calculated value of 75 milliwatts was low, hence we do have a bit of a contradiction. Only way I can resolve it is to assume the capacitor (or his setup) has a significate amount of leakage.
I know it from a constructor who was building a stable near a high-voltage line, then still 380kV. The stable is built from steel load-bearing beams. Every time a beam was raised they got shocks. Only after earthing and steel hoists was that problem solved. But even when tightening bolts, you felt shocks.
Worked at a pool liner factory during the 80's. We'd cut the patterns in the vinyl and and got them ready for assembly by fusion using large machines. There were no need for powerlines for the flourscent lights as the ambient energy made them shone. At my end, with a metal tape measure, when doing my thing measuring the shapes that made up the pool liner, I would often get burned by the tape measure which somehow funneled the ambient energy comeong from the machine's It's all right there;-)
And that’s why we have to bond the water of a swimming pool. I have seen voltage as high as 97 V and people that didn’t want to get it done right I told him they couldn’t use it. So be safe out there. Peace
I worked with these machines which produce high power RF (radio frequency). They induce heat in the vinyl thru molecular friction. Called ''heat sealing". The stray RF would cause all kinds of bad effects including interfereing with airplane coms. Google ''kabar'' or thermatron.
You have an air core transformer utilizing the far field effect from the transmission lines. If you have a normal barbed wire fence there, but insulate each wire from the ground, you could wire each strand in series to produce a useful inductance. The length of each segment should be a harmonic of 59.5Hz. The slightly lower frequency makes up for the load put on the output of the fence. This can then be run to an AC system to run useful things. A phase converter can be used as the interface if the AC system is tied to the grid. For simple storage, I would recommend running an air compressor directly off the fence, then use the compressed air to do work, Just about any system with a motor can be converted to run on compressed air as an inexpensive, compact, and light weight option.
@alexc4924 The wavelength is long, and you would be correct for normal conductors. But these are transmission lines. They are designed to draw the near field back onto the system in a tight distance by balancing inductances and capacitances. If they didn't, they would emit hard-core RF in a bad way.
@@Null-o7j You're not liable for power that gets wasted on your property because it's unavoidable and not your fault, but if you tap some then you're liable for what you tapped. Note that tapping this power increases the amount wasted. It's not recycling.
I worked for a power line construction company one summer and we were adding new lines under existing 110 KV lines. One really humid day, I reached down and grabbed the dead cable running along the sound under the existing lines, and got knocked off my feet by the shock. All the linemen were laughing, because they knew it was going to happen. They explained that electric was being transmitted through the air. They called it "static electricity" but I'm not sure that is really technically accurate.
You can look at how fast he is charging that capacitor, then multiply by the size of the capacitor. For example, if he is charging at 1 volt per second, and he has a 88uF capacitor, the current would be 88 microamperes. Conclusion, it's a very small current. The current from discharging that capacitor is very high though, because the voltage is changed very quickly.
True story... More than 50 years ago, when I was just a kid, the owner of a local oil field welding and machine shop got sued in Federal Court for "stealing" electricity from the 240KV power lines which passed over his property, by way of using a homemade induction coil mounted on a pole. Which in turn was wired into his electrical system, and which had been powering his business for more more than 20 years already. The court ruled that he could not be sued for taking advantage of natural physics, and dismissed the case on day one. His business continued to thrive for another 30 years until his death. Shit you not.
God bless conservatives lol
Great story! Of course, it was the court that was clueless about the physics - or the law for that matter. The intent of the business owner was clear: steal electricity.
@@davidedickjr More like taking advantage of the environmental conditions of his property. How is it different than if the power company built a large concave mirrored glass headquarters that focuses on your property and you taking advantage of the concentrated solar energy that the building provides?
It's not technically stealing. The power is wasted anyways because the field is just being grounded out by the soil underneath.

I knew a man who was in charge of maintaining lines like these. His crew informed him that a property owner had installed an array of wires on his property near the towers. They thought that he was stealing electricity. Management said that if he was smart enough to capture the electricity that they were losing, he was entitled to it.
It would be stealing if you were directly connected. Using waste energy is no different than people scavenging in a landfill.
In Australia and New Zealand it is classed as theft as the power loss to the power company is measurable and therefore chargeable
@@marilynbridges8697 Electrical Engineer here. Unfortunately it isn't waste-energy... it's electromagnetically-coupled (like a gigantic transformer the size of a locomotive), but with a huge air-gap in the middle of the transformer. Any coupling through the air takes power away from the system. No free lunch here, unfortunately... it would be cool if it was free waste-energy for the taking though! =)
It is stealing electricity no matter how you look at it. A transformer hanging on the pole outside your house is in no way mechanically connected. It has two coils and the voltage comes from a primary coil to a low voltage coil thru induction. There is no loss. You are still putting load on the line. This is my 27th year as a journeyman lineman and I have seen everything you can see.
@@t.r.4496there’s always something else to see or learn. Anyone making that claim is just a fool.
As a retired building inspector, I have seen why all buildings must stay back from high-tension, high-power lines.
Among many reasons, electricity can arc through Smoke, especially high-particulate smoke such as that from a wood stove (or solid-fuel burning appliance). Electricity can travel a long distance through smoke. But of course there are Electromagnetic reasons to stay back as well. This video illustrates an example of that electromagnetic energy.
Arc discharge in volcanic plumes is an example at scale. Dusty plasma in "Space" aligns in filaments that stretch light years. Though effectively a vacuum in material terms fluctuating field effects permeate and inform an electric Universe - not just at atomic scale.
I was wondering recently if ferrous ions might be offgassed by my wood stove. I have noted migrating rust-colouring to some rocks on the top.
I hadn't thought of smoke to local power lines - but I've never felt anything sparky from touching the stove.
Other particulates may also operate your observation - such as dust or pollen.
Lots of nano-particulates now sprayed to save the planet. I don't know if they descend without molecular bonding (ie water vapour) atmospheric capacitance isn't just a voltage gradient but a leaky dielectric we call weather (or even climate).
That's interesting and Thank's.....
So Clouds are a form of high particulate smoke facilitating electric discharges called lightning?🤔

@@mmozz8789should aim to be all 3.
I'm a fencing contractor and I can say that I have put up several fences up under overhead power lines and sometime it will shock to piss out of you touching the fence.
That is something to think about. Easements often have gates to control access.
Morel of the Story ? Never Pee on a wire fence near a Powerline ! Check !
Fences near an ehv line should be grounded. If it’s not an electric fence you can ground through standard grounding rods. If it’s electric you need to use an electric fence filter or shock filter. There are several manufacturers that make these.
You should ground the fences to prevent being charged by close coupling.
I remember a story about 20 yeas ago. A farmer kept having bad problems with his cattle. Over a long time he finally found out the MUD had a charge running through it from the power lines.
Instead of shorting a capacitor out to discharge it, use a 20K to 50K, 10 watt resistor across the cap terminals and it will slowly and safely discharge the cap in a few minutes. Remember once a cap is discharges and you remove the short, the cap may very well regain a charge over time. So leave the resistor attached to the cap when not in use.
Thats no fun!

What a load of crap.
as a retired telephone linesman, I've dealt with EMF many times and to all kinds of degrees.The worst was when I was placing a temporary aerial cable under a large transmission line.I was in bucket, and blue spark started jumping between different metal parts of the bucket. I came down and grounded my truck, Still sparks jumping. I ended up finishing the job with hi voltage rubber gloves on, as I couldn't touch anything without getting zipped.
And the customers complained of hum on line
Years ago,I had a customer that was fed by type C rural wire, with the 14ga hardened steel conductors, it was hung on a transmission line on wooden poles, following an ice storm one side went open, and we had a helluva time measuring the open because it induced something like 130 volts AC, and because it crossed a highway ramp it was stupid high, so a regular bucket wouldn't reach, they ended up hanging a 6m strand and lashed a 6 pair drop to it because it was way too far between poles for self supporting drop.
In retrospect, I should have had them lash up 2-19 Gopher wire, so we could have bonded and grounded the shielding, would have really reduced the FEMF and power influence.
Rural "c" was the worst for EMF pick up. I was stripping some one day to lay down in 5502, by my belly. It jumped arch blue spark onto my belly, and thru my shirt. Burned me and a hole in my shirt. I'd have to ground the wire, and I'd have about 20 seconds before another charge would hit.
Another time on an ice storm, 4 guys were picking up some 109 for me on the pole. They picked it up, and all 4 knocked to ground with arch between wire and ground. Again for me to "tie" in the wire on the insulator, I had to ground it out and quickly tie onto insulator. We initially thought we had a primary wire laying on our wire.... but we drove the area a mile or so in each direction ..... no primary. Just EMF.

You can get significant induction voltages from much less than 230kv if you are close enough! I first figured that about 20 years ago while waiting for a train. It was a rainy day, so I had my umbrella up. I was stood on the platform and kept feeling this zapping sensation in my right hand and a faint buzzing noise. I looked up and there were little sparks around the spokes of my umbrella and as I adjusted my grip so as to only hold the plastic handle there was visible arcing about 4-5mm onto my hand. 😵
I was amazed! This was coming from the 25kv traction supply lines about 8ft above my head.
Back in the 70s my friends and I discovered an odd phenomenon. If we were barefoot and touched an unpainted spot on the house gutter downspout with our finger nail we got a mild shock. But only sometimes. Then we figured it out. The guttering was galvanized steel. If it rained, any dead leaves in the gutter would produce a mild acid and turn the gutter into a battery.
Wow that's pretty incredible
Not enough to shock you. Buddy you had an electrical fault.
It may also be accumulating atmospheric electricity.
Funny you should mention acid inside of metal things. I cooked pork chops with apple sauce in a cast iron skillet. I had added garlic and onions and the garlic turned a bluish green color. That didn't deter me from eating it. I turned the (electric) stove off and used a digital thermometer to check the temp of the pork chops. They were done, but still piping hot, so I left them on the stove to cool off. I go back and check the temp, again and a huge spark happened, killing my thermometer. I thought maybe the stove had a short and called maintenance to look at it. They found nothing wrong with the stove. The best I can guess is I somehow created a capacitor and discharged it with the second temp check. I still ate the pork chops.
That's actually a buildup of static electricity. Galvanic action doesn't provide enough voltage to feel.
Here's a neat test to try as we, myself and two fellow electricians in the mid 80's did. We grabbed 8' T-12 fluorescent lamps and wrapped the one end of them with aluminum foil. Then we held them in our hands straight up under similar 230kv transmission lines. They lit up like they were in fixture.
Back in the 90's I was doing work at a Navy VLF radio station. They offered us a tour of the radio house. When they went to show us the cables running out to the antenna array, they just grabbed a fluorescent tube lamp off of a bracket, and as soon as they held it the tube lit up. The cables were running in a large closet that went underground.
This was a Navy prank for any newbies aboard the ship, too. A saltier sailor would summon the new kids out to 'reset the phosphors' in the florescent lights, which meant dismounting the tubes from whatever lights were handy and bringing them out onto the forward deck. The prankster would demonstrate the proper way to 'reset the phosphors' by lifting the tube overhead and giving it a good shake - and a friend up on the bridge would turn on the radar.
When I was an Electrical Operator at a 500kV station we could light up the florescent bulbs without any problem under the 500kV structures.
No need to wrap them in anything....They'll light up underneath a 10KV line already....Just pick 'm up and hold above your head, in the rough direction of the lines....
Back last week, I went into my garage, replaced the fluorescent lamps in my fixture, then flipped the switch on. They lit up as if they were turned on. It was beyond amazing. Then I took the old lamps and threw them into the ocean for the dolphins to snack on.

Another kind of 'step voltage'
About 30 years ago was the first time I became aware of what happens in the vicinity of these towers. A very experienced horse breeder friend of mine married a man that had similar electrical lines running across a back pasture on his property. The marriage saw her move her 10-12 brood mares to his ranch where they were pastured in the same areas with the power lines. I understand that he had always used that area as hay fields, never having run livestock there for any appreciable time. Her brood stock included several older mares, each having produced strong healthy foals for many years. Within the first year some of these mares began experiencing miscarriages or still-births. Like I said, she was very experienced and kept meticulous records of every aspect of her operation. They finally narrowed the cause down to their prolonged proximity to those transmission lines. They moved the herd and never had that problem again.😐

I grew up near a field with some massive lines cutting through the middle, and i would pass through that field all the time. Being a kid, shorter of course, eyes closer to the ground, i started noticing how many 4 leaf clovers i would find under the lines. Then the more i looked, the more leaves i found. well as a kid i didn't know how unheard of this was but seriously, i found some clovers with up to 7 leaves. I wish i pressed some in books or took pictures, because i could find these things within a minute of looking for them, they were all over. But that was back in the 80s, they've since replaced the old giant wooden poles with metal ones, who knows what else they might have changed. I still go back there to look sometimes but i don't find them anymore.
Oh and... yes they were clover. in case anyone thinks I'm full of it. The *other* 7 leaf plants grew on this neighbors property, which i didn't dare get too close to. But, If you do a search right now for 7 leaf clover you'll see pictures of them. They are supposed to be extremely rare.
I've heard the same story from a local farmer, lots of problems from the cattle herd with transmission lines going through thier pasture, they also fed hay directly under the lines because that's where the gate was located. All other herds were fine, same genetics etc.

A length of insulated hookup wire would be cheaper than coax. I would expect a larger power draw if you moved your pickup wire further away from the lines (up to a point) because the wires are carrying 3-phase and the fields cancel to some degree the closer you move to the centre - they won't cancel completely because the wires are physically separated but field cancellation is what the power company would like to happen. The idea is to couple more closely to just one of the wires to reduce the field cancellation effect (make one field stronger than the other two which in effect moves you closer to a single phase pickup).
If you want a decent current, a large loop with one side as close to one of the outer lines as possible and the opposite side of the loop well away would help. This gives a single turn transformer secondary with one of four sides coupled as strongly as possible with two sides not coupled at all and the fourth ideally low-to-no coupling.
In the early '80s, my friends house had powerlines just like that going over their house. The rain gutters and down spouts had a significant electrical charge. Us neighborhood kids loved pushing each other into them or better yet, tricking anyone that didn't know better into zapping themselves. It was strong enough to arc off any grass or weeds that touched the downspouts.
what super powers came from the ensuring dna mutations?
The eighties were fun.
a lack of earthing to your gutters/spouts/plumbing .
An electrically 'floating' conductive surface..... it is best to ground them in general.
Then you don't get zapped.

AC Induction is very common on a long parallel run of metallic cables. I work in the telecommunication industry for over 20yrs and we have to mitigate these induced voltages.
Normally we use AC Chokes to flip the phase 180°. This counters the induced voltages. However, there is a saturation point where the the the AC Choke can be over run and the effects become null.
Generally, these voltages does not produce high currents, but still can give you a healthy jolt.
If you ever heard a 60Hz hum on a Plain Old Telephone Service (POTS) line, then you know why now.
An afterthought to my earlier post. In the late 1970's I owned a cablevision system. Our main trunk line to town from our headend on a mountain was 18 miles long. It was buried along a highway, underneath high voltage electric lines. Each of the 36 amplifiers on the trunk line operated on 60 volts AC, which was duplexed onto the cablevision line, along with the TV and FM channels. We had power supplies every mile or so, which injected 60 volts into the cablevision line, and the further you got from a power supply, the lower the voltage. At around 38 volts we'd install another power supply - and back up to 60 volts again. But amplifiers kept blowing. I mean, like burned up. Since the amps were in underground volts we were perplexed, since they were secure from grass fires. So out with the voltmeter. Surprisingly, we had between 100 and 400 volts on the line - despite putting only 60 volts into the thing to start with. We went through one hell of a lot of amplifiers before we finally figured out that we were getting inductive voltage from the overhead power line! At first we added light bulbs to each amplifier, which glowed brightly and scared traffic. And they would glow bright or dim, as the current load on the overhead wires varied from time time time. Finally, our engineer came up with a fix. A 'crowbar' which used an SCR diode that would short to ground any voltage over 63 volts. So the power line induced voltage would be bled off to ground. Those diodes would get hot like an electric stove element, to the point where we had to heat sink them to stop them from burning out - that's how much power we were getting from the power line induction.
Damn
36 amps, that's must've been a hell
though, back in the day you really only had to care about C/N, unlike today where you have US (for modems) too.
So the overhead lines were how high? And your cable was how deep? I thought lines near/over a highway were 4000V max.
@@MrSummerbreeze01 i read that as the lines were also buried in the ground.
@@twohullsThis wouldn't happen with underground power lines because they have a grounded shield. That's because people and other objects could be very close to them, and the other phases are buried together, rather than digging three trenches, and you don't want them to couple.

Back in the 80's we ran a permanent electric fence around a large farm I was working for. Part of that fence ran under some large power lines coming from a power plant and once that fence was insulated it was hot without being connected to a charger. This fence was 5ft tall with 6 lines and fiberglass posts and the lines alternated between hot and ground, They were all hot under the large power lines.
Sounds like you were wasting free electricity. You should have set up a large scale version of what was shown in this video, and powered your electric fence for $0.00.
so how about legalities there then. if the power company claims that drawing on that magnetic field is stealing their power then it must work the other way round: if they, so to speak, 'push' their power into your fence with all concomitant possible dangers and inconveniences then they should be liable for that. right? quid pro quo.
@@abrogard142 That's assuming the power company would notice, let along care, that he was capturing power leaking from the lines. Right now this phenomenon isn't large enough for there to be a standardized ruling one way or the other.
It very well may be that even if the power company does accuse him of stealing power, he could take this case to trial *and win* thus negating that possibility altogether.
Very interesting experiment!
During the time the cap was charging from 186V to 331V, the average current was 0.19 milliamps. [ i=C x delta(v)/delta(t) ]
This raw current at the open end of the wire will not kill you but the capacitor itself can deliver enough current to be dangerous.
I would wear gloves around this circuit.
A comment below mentions how HV lines affected horses.
I've heard of other cases when HV affected cows and horses. Their feet are always touching the ground and an AC current flows through their body.
not related to power lines, but the NEC has rules for grounding structures for dairy farming. Apparently the smallest of currents traveling through the cows feet will sour the milk, making it undeniable.
@@G8tr1522 Or maybe it's because the fences and guardrails are all metal and in some places you have electrical equipment in contact with it. A colleague of mine managed to kill 10 cows in the milking parlour because he forgot to ground the milk pump and when on the third day of testing the farmer managed to flood it a current of about 40ma was flowing from the pump's chassis through the stainless steel pipes to the metal guiderails for positioning of the cows for milking. The structure was also not grounded and the cows were grounding it out trough the wet concrete floor. Turns out cows are very sensitive to 50Hz currents because all 10 in the parlour dropped dead from that.
@@G8tr1522old wives tail, dairy farms have the same NEC code as any other farm building for grounding.

In a physics class I took a few years back one of the exercises was calculating the windings needed to power a house from the EMF coming off a high power line. Then the final question in the exercise was : "is it ethical?" Well I'd love to give it a try and see how long it took for them to find me out! :D - EDIT - FYI - The power companies monitor the lines for leakage. Building a system large enough to power anything substantial would show up on their test and found out. It would be considered stealing. I hope this puts an end to this conversation.....
I’d say it’s ethical. ✅
@@rogerhargreaves2272 Well it depends on how ethical you think stealing power is. You're setting up an inductor under the power lines that's not free energy, anymore than bypassing your electricity metre is. If you find a water tank, that isn't yours, but the water is slowly evaporating off, is lighting a fire under the tank and then condensing the steam not stealing the water?
It's not "lost" energy that's being recovered, the the transmission losses are LOST, much like how the naturally evaporating water is lost. Putting an inductor under the power lines is equivalent to lighting a fire and boiling more water off. It's just hiding theft in a way where it appears to just be extra natural losses (until someone finds out at least).
Think about an electric tooth brush or at least its charging unit. When the tooth brush isn't on the charging unit, the unit still has AC running through it but it's just resonating back and forth, very little is coupled to the magnetic field it's generating, so that magnetic field is just wobbling back and forth, constantly taking energy but also putting it back into the mains (actually an idling toothbrush unit is way worse for loses than the above, because the above will have capacitors tuned to put the energy back in at the right phase at the substations). The dominant losses in the toothbrush situation are due to a small amount of resistance in the coil that the AC is running through. When you put the brush on the unit though, all of a sudden that magnetic field is driving a coil in the brush, inducing a current in the brush to charge the battery in the brush. The unit isn't making free energy, it's just now being transferred from the mains driven charging unit to the brushes battery.
So make no mistake, it is NOT free energy. Every Joule taken is an extra Joule the electricity provider has to generate in addition to the natural losses they have with transmission system. So the real question is stealing a few milliWatts ok?
Personally, if it wasn't silly amounts of power (i.e. powering your home, though that'd be a lot cheaper and safer to just rig the electricity metre) I probably wouldn't tell anyone.
Lawsuit many years ago cleared a land owner that set up an air vote transformer to pull power from a HV line. I believe it was in California.
My last final exam question was in environmental engineering. I had to determine how long a fish could live when certain chemicals were introduced into its bowl. I answered the fish died from jumping out of the bowl when the chemicals were released. He dropped me from a B to C on final grade!
I'd say that it's free electricity because it's in the air. Would never notice you collecting electricity, because there'd be no loss on their end. Maybe if they were doing maintenance and stumbled onto it, but it's still not illegal. Think of it like using an air compressor. You can't be charged for the air that is all around, although I'm sure that the J P Morgan's of the world would love figure out away to make money from free air use.
We had a small fire in a combine a couple of years ago that disabled the combine. We pulled it out of the field and not really thinking anything about it, parked it underneath some high tension power lines. The header of the combine was sitting on the ground. Later when we climbed up on the combine to work on it we kept getting shocked. That made me believe what you are doing 100%
A great example of an air core transformer. You will get more induction by reducing the separation between primary and secondary, and increasing the length in parallel. Changing the angle between primary and secondary reduces the (effective) parallel length, which reduces the induction.
Looks like capacitive coupling since he's just connecting to one end of the wire. If he went to one side (to couple better to a single phase) and had a larger 'plate' i.e. more wire, he'd probably get more out of it.
You may get better results not using a coax cable being that the core you are hooking up to is shielded. ground the woven metal shielding to the copper on one end. that will utilize the mesh in the induction process.
And coil the secondary for increased inductance. I was watching this and wondering what the result would be if you stretched out a toy slinky and performed the same test.
I suspect a sheet of aluminium foil, or a vehicle, or any other large, flat conductive object would work very well as a capacitor plate. Put it high up, and I'm guessing directly under one of the outer phases will be optimal but experimentation will tell.
I'm going to say you are correct, sir... on all counts.

Very interesting-I’ve heard stories about the impact on livestock grazing under those lines- your work clarifies the significance-thanks
Thanks for sharing!
What does it do to the livestock?
On the farm I grew up on, there is a 120,000 volt transmission line.
One portion is 1/2 mile.
My dad said ... years ago, before steel fence posts were common, (the posts were wood) that 5 wire fence (between his and a neighbor's field) would have an 'induced' current in the top 2 or 3 wires.... enough to receive a "Dirty Shock".
I used to bicycle past a farm property with HV lines over it, I got shocked from contact with my own bike frame and used to see arcs between the fence wires and the ground.
That happened to me once on my bicycle too. It was in the Netherlands.
I have my metal roof grounded within 20 foot of highpower lines. The emf measures at 120 or higher in my addition, so metal siding will be used there, 0 to 8 in the current house also 0 directly under the lines. ?.
@@HarleySeaman-p9h "EMF" is very broad and relative. It is a huge range of frequency, some of which are constant & universal, and some which might be more interactive with matter. But then also, 120 might be 300 on a different meter. It is an absolutely relative measurement.

I now have a dog and cat that will dig them up and enjoy a little extra protein, My meter is Erick Hill RT 100. Thanks, always willing to learn more. I had beets and turnips with the drip lines larger than I had ever see.
I've done some experimenting in this area too. This is capacitive coupling through the air between your wire and the power lines, so you have to use a full-wave rectifier as you are, otherwise the 'air' capacitor simply charges, and you get no power. This setup works to a lesser degree even under 14.4 kV distribution lines. You were likely pushing those diodes near their limit, because when reverse-biased, you have the capacitor voltage plus the peak source voltage in the opposite polarity across them. Of course this is divided across 2 diodes in the full wave rectifier.
Yep, it sounds like you have done this before. Thanks for commenting.
Thank you sir for your efforts, in both braving the cold and the testing. I am in Wisconsin and it's -9 this morning so I know what your dealing with in that regard. As to your test and charging your capacitor I am not surprised of the amount of passive power you captured. Depending on the transmission flow rate in the wires, the equation for radiated power would show that a capacitor several times your 1200 volt rating could be charged (given the bridge rectifier having diodes of sufficient rating to handle the load. Excellent job and very informative enjoy you very much.
Thanks for commenting. One more night of -18˚F, then we are expected to be above zero. 👍🏻
🔌🔌In 1977 I worked in a utility transmission department as a COOP Electrical Engineer in southwestern Michigan that had 765kV power lines from the nuclear plant. An individual claimed that a fence caused a spark in his tractor. Sure enough, we found out that this could happen and caused a change in easements setbacks. We also tested 69 and 230kV. 765kV was much more likely to spark. Also, the blowing sandunes caused the land-to-plow line clareances to change drastically.🔌🔌

I remember us having to dig an underground ground grid. and place ground rods down all over and ground cables all tied together to keep the induction down.
Great video! You might try coiling wire into plastic barrels to see what effect you get. About 25 years ago there was a fella here in Phx who was gathering enough of the power leaking out of the HV lines that ran across the back of his yard that he was running his house on it for free. When the power co. found out what he was doing they were big mad, but the cops & court said he was breaking no laws so they had to leave him alone!
I've heard about this phenomenon back in the 90s. But they referred to it as "stray voltage" and tell you stories about cattle getting electrocuted, and homes that were next to lines would have all kinds of problems, as well as the occupants coming down with weird illnesses and cancers.
I believe there was a huge lawsuit in Iowa maybe fifty years ago over this issue. The farmers were trying to prevent being forced to have these power lines cross their land, sometimes very close to a house or barn.
Non-ionizing EMF can't cause weird illnesses or cancer. There is no physical mechanism to do that.
Years ago I read about links between high power lines and what medical researches called 'cancer clusters' which were the people, mainly children, who lived in low cost housing built near to the lines having significantly higher levels of several types of cancer. The power companies were not found liable however those people in the lawsuit were offered alternate housing away from the power lines out of the kindness of the companies heart.
@@bendover1028There is exactly zero peer reviewed research that shows anything of the sort. None. Nothing. There is no physical way that non-ionizing radiation can possibly cause such damage.

I am 79 years old and 50 years ago I had a girlfriend also now in her eighties who contracted the dreaded MS disease. She lived very close to powerlines and some scientists wondered if powerlines were the cause of this and other illnesses. Your experiment just shows what is radiated from these lines and possibly affects millions of others. This lady, badly crippled has lived in a nursing home since 1990 bless her. I think that there is a massive cover up of the hidden damage done by radiation such as this and I am glad that you have highlighted it. Well done. B
if power lines cause disease, why don't microwave ovens? Short answer: non-ionizing radiation is not the same as ionizing radiation (WHAT A SHOCKER!!)
also, power lines don't cause disease. Stop with this nonsense.
Well, it shows energy is radiated, but not that it causes problems. Remember it's taking miles of metal fence to pick up this energy. And if the fence was connected to ground, it wouldn't be detectable.

Retired land surveyor. Whenever we surveyed under hi tension lines and set up the transit you could feel that it was energized because it would 'bite' when you touched it and if you grabbed hold of it it would 'buzz' in your hands.
Kreosan did this but they also used a transformer (it might have been a car ignition coil or perhaps a TV fly-back transformer). They had a rectifier of course, but also some kind of voltage regulator. With this setup they could harvest enough energy to charge a cell phone with the antenna just being a one meter whip and the ground the frame of one of their bikes. The lines they were under though were the big ones, maybe 500KV.

One job assignment had us inspecting a storm drain under a 240KV transmission line... It knocked two of us down stepping back onto the truck after hooking up the camera to that cable. EMS was called, and it finally dawned on me WHY we got shocked. I got 480VAC between the rebar of the catch basin and the frame of the truck. SHOCKING, huh?!
The same thing holds true for shunt fed and broadcast towers. I used to manage a tower facility in the Northeast that was adjacent to a school and had a chain link fence around it. Every time I would bring my key up to the lock it would draw an arc because the fence was electrically hot due to the RF field and the highly reactive antenna.

Once the smoke was cleared, I went inside and observed the damage. The Harris SX5 has totally melted down. The contactor that did the switching was in the top of the SX5. It's insulators were made of some sort of fiberglass/waxy paraffin material, and when the contactor drew an arc, the arc sustained and caused the waxy materials to ignite, dripping down flaming debris into the lower part of the transmitter. It was a total write-off. I didn't want to tell the owner "told ya so!", but I think he knew.

There's a historic railroad SMRS IN Michigan USA that one of the volunteers was an elect engineer. He became perplexed about an 1890 railroad bridge not rusting hardly any. Checking metal composition possibilities and anything he could think of couldn't figure why. One day I told him why I thought it was natural magnetism since the rails went mostly north/south and not having rail traffic much of the year it induced a small anti corrosive charge.
He said didn't think of that and would explain whole thing.
i'm already shitting my pants watching him load that beefy capacitor to >900V
You tested e-field pickup. You might get more power from residual magnetic pickup, and the voltage would be safer - you can run a 'fence' wire along the ground under one of the outer lines, and a return line a few meters away from the power line. This should be a much lower voltage around your loop and might be a useful amount of current. You might also find it is mostly 180Hz (third harmonic) due to most of the 3-line 60Hz cancelling itself out!
You are correct but I just perused all comments and yours is the only one to state that.
Yeah - is it the dielectric field that would be captured ? I would not think there would be huge current and huge magnetism being transmitted but the electric field would be enormous - and what of the 'theft' issue ? does pulling field off deprive the field ? or is the field just wasted emissions ? my guess is "B" so no theft
Cool. I was thinking on the same lines as you. No pun intended. Can you imagine the size of the magnetic field and it's density around that heavy conduit carrying how much voltage??? Yeah.

It's the amount of power and the distance from the wires that matters. Sure, I can do the same thing in my home, right next to the wiring in my walls. This guy is doing it at distances greater than the width of my property, and getting more power!
So no, I'm not worried about the power in my home, but yes, I am worried about high tension lines. I also don't like the fact that power companies get government support to maintain and repair them. It was their choice to put them up high instead of burying them, and it's their equipment. Let them deal with the consequences.

Caution, you can accumulate enough induced voltage in your “fence” wire alone to stop your heart (1 - 4 amps). I’ve lost a co-worker to very similar conditions. Don’t experiment and loose your life.
It only takes about 20 - 40 milliamps to cause fibrillation. The higher amperage is actually better, since it will stop the heart - meaning it is easier to restart.
You should put a 50K resistor and amp meter across the positive and negative leads to see how much the voltage might drop to. To measure the resulting current and see the usable DC voltage available. Maybe see if it could power some LED Christmas lights. :)

Wow! What an interesting experiment, and the comments below are just as interesting. Anyone can see clearly what is going on here, which we should all be aware of. Many times, I have walked areas where these run through because the easement makes it easy to walk through, like national parks and other areas, it is kept mowed down and, on a hill, it is easy to see long distances. So, that amount of energy is below and in surrounding area all the time! It does affect living things..... and could cause some issues I would think! Thank you for this video, it is very amazing! I am going to share and put it in my community spot so others can see too (if anyone looks). Thank you so much and You stay safe!
careful, alot of times locals like to setup makeshift firing ranges on these straightaways
Your DC voltage will be 141% of the AC voltage in the Coax. DC wont inductively couple as well but it doesnt transmit over distances well either. Get a Fluke meter and the Fluke 40,000 volt probe. We had to run autotransformers buck transformers on large multifamily residential jobs so we had 120 volts at the end of 300 to 500 feet of extension cord. Otherwise we burned up our power tools. We'd tap off at 152 volts and sometimes only had 110 at the end of the cords. You cant help but lose power over distances.
You could put a step down transformer on the end of your coax wire, that would decrease the voltage to your bridge rectifier, but it will increase your amperage to a usable amount, that you could run a burried insulated cable, to your house, to keep a battery bank charged to help you reduce your electric bill. 😁👍
It would be awesome if _somebody_ made an animation depicting the setup that you're describing....🙏 😁

Good video on describing lines of flux called the left hand rule. The lines off flux coming off the high voltage lines is pretty significant. Higher the voltage, the larger the lines of flux. The RF cable you are capturing the voltage is pretty cool but use caution when doing this.
'Left hand rule' lmfao
Fleming’s Left-Hand Rule and Fleming’s Right-Hand Rule are essential rules applicable in magnetism and electromagnetism.
@@xxportalxx.
The higher the CURRENT, the higher the magnetic flux.
The distribution network uses high voltage lines specifically to reduce the current and magnetic flux levels.

It’s really wild how much inductance is happening under those power lines I was on a transmission line building crew and it would charge the line we were building beside it to 29,000 volts and when we put the grounds on it would make at least a 6’ arc. We also had fun with the static from it. We would make little wire pistols and shock each other on the neck or behind the ear haha
A guy I went to school with built his house right under those power lines, the large ones with the steel triangle support tower. We studied electrical engineering, I thought he was nuts for doing that. Grand kid was born with all sorts of issues and didn't survive more than a few months. AC power is nothing too be fooled with or taken lightly, some engineers don't even realize that.
@@jedclampett3725 Spoke to people in a housing tract built underneath massive high voltage transmission lines, whilst canvasing for a sales job out in the backwoods of TX. The residents of that little housing tract had lost multiple members of various families to cancer and other ailments that could not be explained. A study had been done to find out why everyone was dying there, and the only common denominator was those high voltage lines. They were all convinced they were the culprit.
> . . . when we put the grounds on it would make at least a 6’ arc. <
The dielectric strength of air is about 1,000 volts per millimeter, or 1,000,000 volts per meter. 6' is 1.5 meters so are you saying that you developed 1.5million volt arc?, and lived to tell about it?
An arc of six inches in dry air corresponds to 150,000 volts, which is also courting death if there is any current at all behind it.
@@peteinwisconsin2496 Yet Tesla and Mark Twain played with that electricity in Tesla's lab all the time. I guess when you know what your doing, you can get away with doing dangerous stuff. Re: Dangers of AC power. Read "The body electric" by Robert O Becker the last chapter is how he tried to convince utilities to not use that frequency because of the harm it can cause. Tesla tried to warn them as well. They weren't having it. I guess it was intended to cause damage and feed the healthcare industries profits.
Thank you for creating this video. I've felt tingling when up around high voltage transmission lines. I didn't think it would be healthy to spend a lot of time around them, but I didn't come up with a method that would allow them to be shock dangerous unless touching them some how or coming close enough for them to arc. This experiment shows that it is conceivable that it is a possibility some type of configuration might emerge that could store energy and create a deadly charge. It would likely be some weird like some piece of equipment with a hidden high voltage compactor that somehow gets a conducting induction loop by chance created to it under a high voltage transmission line. It is in a trillions of a chance, but some association of junk under transmission line could have that happen.
I'm surprised there is not more videos in the popular science/mechanics venue that bring up how much energy high voltage A.C. transmission lines loose through stray induction to their surroundings. Another characteristic would how much they loose by radio wave radiation. Typically I'd assume radio wave transmission loss of energy is close to zero, but not zero compared to the energy in the line.

We were working on a road to a radio antenna near a power generation plant. Not sure what the voltage was on the HV transmission lines, but I had parked my F350 crew cab long bed under the transmission lines perpendicular to the lines. Chrome door handles and I had a very hard time getting the door open to get in. Every time I touched the handle, it hit me like an electric fence.
Thanks for sharing!

I work for over 30 years for a utility and one of the problems in the high voltage switchyard is inducing a voltage in fences and handrails, even thou these things are grounded, you would get a shock. There is no current when this happens so no health problems but still a SHOCKER
Reminds me of the foxhole radios i made in my youth; Was always amazed that a small antenna pulled enough voltage from the air to run a piezo speaker earpiece.
I was an RF tech, we tested potential cell sites, and would use a bucket truck to hoist the antenna to the proposed height. To look both for potential coverage and obstacles, I would go up in the bucket and take pics on the 8 cardinal points to get a 360 view. One time we were proposing mounting to HV transmission lines, the SDG&E guy opened the gate and drove away, so we went about setting up. I was about 8 ft from the lines, in a metal framed bucket. My compass went nuts (actually reversed polarity) and as I reached for the controls I got BIT, not deadly, but I crossed my arms and had the driver lower me from the ground controls. Later talked to the SDG&E guy, who had no idea we were setting up, that close to the lines and said that would NEVER work, as it's inside the 'field' and it would fry the antennas! that compass still points south!
They had you in a bucket 8 feet away! WTF?
I worked for Hydro-Quebec. They used to remove the direct connection to ground of the "ground wire" and do it through lightning arresters. They would pickup the voltage from that line to power a remote substations.
Fascinating video. I want to be sure to say thank you to a brother Knight.
I don't know why this popped up in my recommendations but I'm glad it did.........was really surprised by the amount of juice you were able to store.
As a pipeliner I’ve worked on many projects laying pipe , like 36” or 42” , along power line R.O.W. We have to ground every piece of pipe brought in just while laying there under those lines. Heck yeah they build charge !! Seriously no joke.
I've laid quite a bit of pipe in my day, too. 😉
I knew a guy that pretty much powered his big barn and shop with big sono tubes wrapped in Romex, that he buried under the big power-lines that ran across a field behind the barn, his house was powered by panels. He was totally off the grid.
An acquaintance of my mis spent youth used to have a pneumatic -- It looked like a potato gun -- that fired a sabowed chain that would create a bolt of lightning upon striking transmission lines. He did it to a distro line in the evening once; no lightning but four blocks went dark. Crazy stuff.
I worked at a company called Genscape in Louisville Ky years ago. They sell reports about commodities to brokers and one of those reports was on what electricity was going where and who was selling electricity to whom based off of boxes they paid land owners to place next to high voltage power lines that measure how much electricity was going through the line based off the magnetic fields.
That's interesting, not the boxes, but the fact they totally bypass the power company and make their own measurements. Because the power company would already know this stuff but they don't want to ask them.
@@thewhitefalcon8539 It not a matter of willing to ask its a matter of the power company willing to release or quickly release. These commodity brokers trade on that info daily sometimes hourly. An example would be if Con-Edison has a problem with a plant and has to buy power from Duke Energy. The brokers would invest in Duke Energy supplies. It is big money. They use FLIR cameras on oil tanks like those at Cushing to provide oil stockpiles info to brokers. They use satellite phots to predict soy and corn yield for Ethanol production. Huge money in those reports.
My parents spoke of a city park in their home town in Germany where there was a park that had all the lights powered by overhead high tension lines. No wires to the lights, just a collector on top of the pole.
Back in the late '60s and early '70s, I tried to convince my Grandpa and Dad to let me put up a few loose coils of wire at the edge of the treeline and run them to a few lights along the horse path along one section of fence. This was back about 50 feet or so from the easement where the high tension towers ran. My Grandpa complained occasionally about being caught in the dark on that end of the farm and I figured putting up a light every 100 yards or so would provide enough to orient back to the house if caught out after dark. They were convinced the power company would come after them, but I couldn't convince them it was all loss for the power company anyway. The minor amount we'd get for a dozen light bulbs wouldn't even show, since it was loss anyway. It wasn't like I was going up a tower and hanging a coil up there. I always meant to run out with a coil of wire, a light, and a meter and see how much we could get, just to know, but never did.
Thanks for the comment!
Could animals get hurt from this? Could it start a fire?
I remember going up on the hills near where I stayed a few years back with a fluorescent tube. When I stood under the 400kV lines holding the tube vertically in my hand the tube lit up from the top of the tube down to wherever I held it. It wasn't super bright but that was due to the field created under the lines being capable of producing only a low charge flow through the insulating air and if instead I had erected a small wire array say 2m in the air and had electrically connected one end of the tube to it and hung it vertically down and earthed the bottom end of the tube to the ground it would be very bright and the brightness could be varied by raising and lowering the top wire array. You could have done that easily enough.
Enter LEDs:)
Many moons ago I was installing a new audio system in a strip club near the Rio in las vegas. After troubleshooting some noise and ground loop issues, I discovered the earth ground to be the main source of the various problems with that building. I was told by an engineer that the city has areas where this can be found and measured. These spots would also migrate around the valley. The dry desert ground and the high demand for electricity, mostly from the Casinos, being the reason for this.
Excellent practical demonstration - and cautionary tale. I was interested in the charge rate and wondered if I plotted the voltage vs time if it would show the expected exponential curve. (data for the curious: 2:04/0V, 2:36/180V, 3:45/328V, 4:38/423V, 5:10/478V, 5:37/515V. Stopped there because of the glove break.) It does initially but then the slope stays the same. Interesting. A friend of mine worked at SNC in Wisconsin. One of their products was a device (probably a common-mode choke) used in rural land-line telephone systems prevent phone techs from getting killed from just the thing you demonstrated. Think about the power in a phone line that runs close to and parallel to power lines for miles! Yikes!
Telephone cables are normally fully shielded, and the shield is grounded. Only the drops going to houses are unshielded.
@ethanlamoureux5306 it's not the case in my area. The pairs aren't shielded, they're twisted and don't even have a guard wire. Many of the copper pairs are within 4 meters of 33kv aerial lines.
@@dinosshed That may be true in some cases, altho I have only ever seen it on rather old, smaller cables with few pairs, such as a 6-pair drop. Bear in mind that when I say shielded, I don’t mean each individual pair is separately shielded, but rather the whole cable is normally protected by a corrugated metal shield just inside the outer jacket. This protects against physical damage as well as electrical interference. The oldest cables used lead jackets, and when they moved to polyethylene jackets, they also started using an internal shield to do the same job as the lead jacket.
@ethanlamoureux5306 I used to lead wipe the mains and repair the air leaks on them. Some of the aerial cables were shielded, but they were rarely joined with the strapping.
If it took 213s to get to 515V, that works out to 11.67J in 213s which is... 55mW. So this could keep a small light lit indefinitely.
An electrical engineer told my about this trick already 30 years ago. Evidently it works even better near a radio station.
I used to install central vacuums.
I was finishing an install at one particular house After all the connections were made, pipe and low volt electrical, I plugged in the main power cord. The motor came on as soon as I plugged it in. I thought I had miswired something. I went back thru all of my low voltage connections as it just sends 12-24v out to each outlet and if it comes back, it trips a relay for the motor. I couldn’t find any shorts in the lines. So I put a meter on the wires to check for continuity between them and had none. But why was the motor turning on with the low volt lines connected and not on with them disconnected?
The only thing I could think at the time was a bad circuit board or maybe the radio station across the street had something to do with it.
I went to the local RadioShack and picked up a power supply and a relay and got them temporarily going with the understanding that I would be back again once I figured out what was happening.
After contacting the manufacturer of the system, they sent me a new circuit board and that fixed the issue. It turns out that they had ran into this before and it was indeed the radio station causing the issues. The low voltage wiring was acting as an antenna and picking up stray voltage that was triggering the onboard relay.

When looking for a new house, I was aware of the EMF surrounding high tension power lines. One of my stipulations was that the house be at least a quarter mile from any transmission lines. My extended family thought I was nuts...they built immediately adjacent to to transmission lines because the property was cheap. There are well documented effects of EMF and young people inducing lukemia. They have three young boys. God help them.
We bought adjacent to a 230kV line, and I didn't even check with a Gauss meter, but did have a plan. The house has aluminum siding. The second month here the steel roof went on. The window screens are now all aluminum. Five bars outside the (steel) front door. Zero in the living room and bed room. Not perfect, but the gardens are further from the HVL and I worry more now about just carrying the phone.
This works. We had HV lines running directly over the horse corral at a property we lived in a short time. I would take florescent bulbs out there and show people how they lit up just holding them up under the lines at night.
But don't dare try to hook anything up, they will find that drain.
Another good one is wire fences around large broadcast transmitters, when the fences demodulate the signal and you can listen to the show.
I've done that, it's pretty cool.
Many years ago I was setting light poles with a bucket truck in a parking lot. There was two maybe three, HV lines (systems) above, I can't remember. I was in the bucket operating the boom. I reached out to grab the pole to stabilize it and got a tingle. I told the guy down below, he though I was just blowing smoke. When he grabbed the bottom of the pole to center it on the light base he got a surprise. He took his lineman,s pliers and grabbed the ground wire from the feed wires and weld it close to the pole. there was a continuous arc. One of the guys ran to get some rubber gloves. It was all good once the pole was sitting on the base.
Thanks for sharing!
That one Pole was inducing more power to ground than I would need to run the lights in my shed. I'm rather surprised that the right of way allowed those poles to go up at all.
Back in the mid 70’s I was a Crane operator in Phoenix AZ. We were on a job North of Flagstaff in a small town called Grey Mountain. Arizona Public Service a power company was installing a large electrical transformer. In this business everything on the job including the crane is required to be grounded. As I was sitting in the cab of the crane the linemen were in the process of grounding the crane. We were located in an area similar to the power lines in the video….i looked down and to my surprise I noticed them laughing as by removing the ground wire that had been attached to my outrigger I could see them using a electrical arc to etch their initial’s in the paint of the crane.
What you aught to do now that you know it'll go over 1kV.
Is to devise a small auto-discharger, which will drive across the gap of a neon / gas discharge lamp, such as a large street lighting luminaire, so that when you go back home, you can still se this contraption pulsing flashes every so often like a search light, especially if you aim it directly skywards (vertically orientated).
Then if the power company ever complains, just tell them it's the automatic visual warning system, alerting you whenever the power goes out (by the lack of light) - to complain to them for not maintaining their own distribution services.
After all, if you think they are losing power, consider how much "more" is being lost all along the length of that high voltage network, between their overhead wires and the ground (earth) below them, s 100% totally wasted power.
It's just a fact, that these emf's will be generated all along the aerial cable routes, on any given day, right across the country, just a smidgeon - in the daily life of being a power operator.
Thanks for the inspiration! I was thinking of an 'Electro-Smog Indicator' at the edge of the easement. 😁
Having been a crane Operator for the power company you can definitely build a charge by induction being close to power lines , and can be deadly if you are not very careful
Nice experiment¡. With 1KV reverse breakdown diodes you probably wont get much past that voltage on the charging DC capacitor. That's because the line voltages are alternating above and below ground potential (I agree with other comment in that there should be a mix of harmonics depending on the distance between the pick-up wire, witch doesn't need to be coax btw, and the HV lines in relation to the distance between the different HV conductors themselves). Anyway, because your DC capacitor terminals are ungrounded, usually the positive terminal will sit above ground potential and negative terminal will sit below ground potential. When the incoming or pick up wire picks a voltage of say 500V below ground, the diode of the rectifier that is connected between the positive terminal of the capacitor and the incoming pick up wire would get a reverse voltage of 1KV if the capacitor is charged to 1000V (Would help to see a diagram of connections and potentials referenced to ground). Conversely when pick up wire gets 500V above ground, the diode that is connected between the negative terminal of the capacitor and the pick up wire would get a reverse voltage of 1KV when the capacitor is charged to 1000V. Because of the relatively low current, the diodes would conduct in reverse without getting destroyed. The way to get higher voltages on the capacitor would be to connect the pickup wire to one terminal of the capacitor and the other terminal through a series of diodes to ground. That way you could reach n*1000 V on the DC capacitor, assuming that the cap has enough voltage rating and you use a series of n diodes rated at 1KV of reverse voltage. Of course you would get a half wave rectifier, so half the incoming current
For anyone wondering, the rate of charging this capacitor corresponds to around 77 mW of power
= 0.077 watts. I looked up the power use of a common 5mm red LED, and find they use about 15-30 mA or about 0.05 - 0.1 watts at nominal LED voltage (3.2v). So I think he is pulling enough power to continually light a single 5mm LED, but definitely not at it's full brightness. I think this seems in line with the old school trick of standing fluorescent tubes straight up from the ground-- they will usually glow dimly if they are under HV lines. Seems like he will need a lot more conductor to pull any truly useful power.
@@gutrali Using field strength falloff it seems that his "fence" would have to be around 18.5 m (60'8") high to get 1 watt of continuous power with current length lol
Thanks for calculating that so I didn't have to
Yeah that's SUPER tiny. I figured it was in the sub 100 mW range. It can't be much.
@@ac281201 but 60 ft would be higher than he estimates the sagging lines are off the ground already. I think it would help if he created a cool rather than just a Rf antenna like he has here; no grounded far end
That was an excellent practical demonstration of the Right Hand Rule !!
The power you can get from the fence is proportional to the current flowing (not voltage) of the transmission lines. So, sometimes you will get very little, sometimes you will get a lot more.
I wonder if the 3 phases somehow cancel each other - would be interesting to setup a few "fences" with one right under the middle line, and the others a repeating distance apart moving away from the lines.
Field lines don't cancel, they change shape to accommodate a zero-flux boundary between the two opposing flux directions. With the 120* phase separation I'm not really sure what would happen with the flux and would quite honestly be a great simulation to run, seeing the distribution would sure help with designing a better secondary.
On lower voltage lines around the Pole Transformer getting 8000 volts ? - is there any sensitive meter that would detect current flows (producing magnetic fields) from below the line ? or would we need a clamp on meter to the HV line ? I was under the impression it was a dielectric field that was transmitting out - but I don't know enough.... to know
There is not likely to be a balanced load on the transmission lines so I would think the flux pattern would be a field created by the imbalance.
3 phases partially cancel each other, but not precisely.
@@thewhitefalcon8539 if the current in each phase is equal they do cancel each other out. Cables are installed in tri-form to take advantage of the effect.
This has actually come up before. The way to actually harvest the power would involve placing a rectifier on each end and then collecting the power probably with shielded cable of some sort. The gizmo that does this is called a “rectenna”. (I Tryed to post a link but my phone isn’t cooperating. You can just search for the name though.)
One little catch, you still have to pay for the power. 😕 When I say this has come up before I mean it’s come up in legal history. Power lost to unconnected conductors running parallel to the power lines is simply a loss that the power company has to eat. The moment you connect it to something you have “monetized” it. 🤷 That’s when the company in the business of selling the electricity gets a say in it.
I feel like thus actually might be useful in areas without a normal tap but legally speaking it is something you do have to pay for.
Interestingly this appears to be what Nicolas Tesla was referring to in his early work about wireless power transmission. It really isn’t practical for transmission of any amount of power for the equipment of his age but it might be useful now. LED lights have ratings of “something point something” watts. 😳 Well, maybe!
Power company will also notice an increased power loss in their transmission. They will notice if you draw very much power over time.
0:45 The Fence is Catching the Electricity, Not Stealing it. The Power from The Hot Wires Overhead, is Naturally going to Ground.
This is not how electricity works
Nope, not how electricity works. The fence is being charged by induction and the power is sapping power from the electric grid. This will cause resistance in the power grid and the power company will need to supply additional power for this
Cool experiment. You should try putting your multimeter in Amperage mode, and put it in series with that circuit. I t would be interesting to see just how much current is flowing through that circuit.
Thanks for the post. As a lineman it’s always interesting to see people outside of the industry taking an interest in how our energy is delivered, most people don’t understand what goes into the generation,transmission and distribution process. Great work.What brand of hat are you wearing at the beginning of the video?
Wool Crown cap made in Canada
If you interrupted all the ground wires on a bunch of poles with a very tiny Gap and siphon the power from the wire connected to the wire that runs along the bottom when there be a whole lot of power coming out of that and hopefully the tiny Gap make it interfere with lightning protection. You may have to do it with a nice related set of polls like two of them and just have a wire strung right below it I think he might know what I mean as a lineman you could string an additional wire between two poles and connect them to something deciding off the power see what kind of results you get from that I think you would have a lot of power it's constantly running into the ground and that should be able to be siphon dog maybe the utility company could try that on a large scale and see if it's anything viable
Once you start messing around with the power company's poles, you are going to get in to lot of trouble.@@yonkromis7883

Harvesting wasted energy from antiquated, inefficient infrastructure. Very smart sir.
It's not really the fault of "antiquated" infrastructure. When superconductivity is practical, efficiencies will increase. Whether the line was built in 1922 or 2024, present technology will be inefficient due to the (past and present) fundamental economics of transmission system design. Let's see what happens once we depart from ACAR, ACSR, HTLS and ACC conductors with significant corona losses. Superconductivity will hasten this advantage.
This comment was necessary to keep our humility. No real innovation here just skimming fat off a broken energy transfer system.
Nicola Tesla, where art thou?
I have often wondered about this. However, your experiment needs to be expanded. Laying your fence across instead of in line either the path & adding several crossings. The lack of a load means you cannot measure current & therefore calculate power capability (Volts x Current). I always wanted to put a couple of turns around the base of a steel pylon to test this...
It would be enough to run a cattle fencer, a repeater for ham radio, an LED light on a sign or driveway, or to charge or permanently maintain a small device or parked vehicle battery.
You're quite wrong about lack of load. The load was the charging of the capacitor itself. And during the approximately 480 seconds that he was charging the capacitor he collected 36.2 joules of energy. Another name for joule is watt second. So he was collecting energy at a rate of approximately 75 milliwatts.
@@johncochran8497 I agree with your method of calculation, but I see there was an interruption in the video at time 5:53. Up to that point, the energy collection rate (power) calculates as 55 milliwatts. After that, from time 6:03 to time 10:00 at the end of the measurement, the power calculates as 59 milliwatts.
However, the actual power collected would be a little higher since the voltmeter, while it is briefly connected, draws power. That meter presumably has an input resistance of about 10 megohms or 11 megohms. Assuming 10 megohms, the meter consumes about 81 milliwatts at 900 volts. He was making brief connections. The voltage was definitely climbing in the periods when the meter was not connected. It seemed to also be climbing while the meter was connected at the end. If so, that would say he may have been collecting over 81 milliwatts in that configuration, but I can't tell if the meter was connected long enough then to be reliably responding to small changes.
@@analog_guy I failed to notice the cut at the point you mentioned, so that would mean that my calculation of 75 milliwatts was high. As for the parasitic draw caused by the meter, I would consider that to be extremely negligible. Although you should be a bit more careful about the difference between power and energy. If the meter was 10 megaohms, then I agree that at 900 volts, it would be consuming at a rate of 81 milliwatts. But assuming 5 seconds for the measurement, it would have consumed approximately 0.4 joules of energy.
But there is the issue of the meter voltage reading actually increasing while the voltage was near 900V. That increasing value would imply that the power being supplied exceeded the drain caused by the meter, hence > 81 milliwatts. But the scene cut would imply that the calculated value of 75 milliwatts was low, hence we do have a bit of a contradiction. Only way I can resolve it is to assume the capacitor (or his setup) has a significate amount of leakage.
@@johncochran8497 That is a good observation.
I know it from a constructor who was building a stable near a high-voltage line, then still 380kV. The stable is built from steel load-bearing beams. Every time a beam was raised they got shocks. Only after earthing and steel hoists was that problem solved. But even when tightening bolts, you felt shocks.
Worked at a pool liner factory during the 80's. We'd cut the patterns in the vinyl and and got them ready for assembly by fusion using large machines.
There were no need for powerlines for the flourscent lights as the ambient energy made them shone.
At my end, with a metal tape measure, when doing my thing measuring the shapes that made up the pool liner, I would often get burned by the tape measure which somehow funneled the ambient energy comeong from the machine's
It's all right there;-)
And that’s why we have to bond the water of a swimming pool. I have seen voltage as high as 97 V and people that didn’t want to get it done right I told him they couldn’t use it.
So be safe out there.
Peace
Was this caused by static electricity in the vinyl?
I worked with these machines which produce high power RF (radio frequency). They induce heat in the vinyl thru molecular friction. Called ''heat sealing". The stray RF would cause all kinds of bad effects including interfereing with airplane coms. Google ''kabar'' or thermatron.
You have an air core transformer utilizing the far field effect from the transmission lines. If you have a normal barbed wire fence there, but insulate each wire from the ground, you could wire each strand in series to produce a useful inductance. The length of each segment should be a harmonic of 59.5Hz. The slightly lower frequency makes up for the load put on the output of the fence. This can then be run to an AC system to run useful things. A phase converter can be used as the interface if the AC system is tied to the grid. For simple storage, I would recommend running an air compressor directly off the fence, then use the compressed air to do work, Just about any system with a motor can be converted to run on compressed air as an inexpensive, compact, and light weight option.
I think it's technically near field. The wavelength of 50/60Hz is really long.
@alexc4924 The wavelength is long, and you would be correct for normal conductors. But these are transmission lines. They are designed to draw the near field back onto the system in a tight distance by balancing inductances and capacitances. If they didn't, they would emit hard-core RF in a bad way.
Doable power can be tapped, but at your own peril- both physically and legally.
Pretty sure this would be legal? The power is "on" your property.
The power company lawyers would disagree. It's theft.@@Null-o7j
@@Null-o7j You're not liable for power that gets wasted on your property because it's unavoidable and not your fault, but if you tap some then you're liable for what you tapped. Note that tapping this power increases the amount wasted. It's not recycling.
I worked for a power line construction company one summer and we were adding new lines under existing 110 KV lines. One really humid day, I reached down and grabbed the dead cable running along the sound under the existing lines, and got knocked off my feet by the shock. All the linemen were laughing, because they knew it was going to happen. They explained that electric was being transmitted through the air. They called it "static electricity" but I'm not sure that is really technically accurate.
I'd be interested to know what the max current is?
You can look at how fast he is charging that capacitor, then multiply by the size of the capacitor. For example, if he is charging at 1 volt per second, and he has a 88uF capacitor, the current would be 88 microamperes. Conclusion, it's a very small current. The current from discharging that capacitor is very high though, because the voltage is changed very quickly.
