I love how electrical components can all be reproduced in an hydraulic system, this is definitively a DC/DC boost converter (the inductance is water inertia).
Very noisy signal and very inefficient to be to be a boost converter..
@@omniyambot9876 This is however a rigorous hydraulic analogy.
Yeah I guess
@@IncroyablesExperiences But it's a PWM maybe
I literally yesterday was thinking about this same exact thing.
I was thinking about how water could push itself with release of energy, akin to how batteries release electrons from one side and grab them from another.
Really interesting! This works in pretty much the EXACT same way as a boost converter in electronics (converts a lower voltage to a higher voltage, but with less current). Crazy how similar fluid dynamics and electronics are!
one of the only differences is that electricity has no weight, otherwise electrons would be like a fluid and those two would be the same thing
Yeah it's really cool to see similarities across various mediums of energy transfer.
Back in the 1700`s, churches and cathedralls and other huge building made their own energy by Eather, just out of ''thin air'' with antenna`s and coils, the people who build that powerstations called Tartarians, many video`s to find on youtube..
Guy`s like mr Edison and rockefeller destoyed al those technologie and forced us to use oil to create energy..
But the still use it for own use.. and many buildings are still using this technology but the ''normal'' people don`t know that.
As an apprentice 45 years ago our instructors used to use that analogy to help trainees understand how electricity works.
@@todaywefly4370 no way! That’s awesome! It really is pretty much the exact same. Did they use just a manual switch, or use a semiconductor (like a MOSFET, or maybe a BJT for that period)? And damn… 45 years ago was the year my parents were born. Love how the internet allows people to connect across generations.
HI from NZ. I sudscribed in about 10 seconds. You explain things clearly and concisely. That was a great demonstration. My family used to live in an old house that was badly damaged in the Christchurch 2011 earthquakes. We had an old Ram pump in the front garden that pumped water to 2 x holding tanks about 4 metres off the ground. The pumping ratio was 2/3 wasted to pump 1/3 to the tanks. The waste water was piped off to a nearby river. This house used to have 7 Ram pumps and provided water for the whole street. Another man who lived close by also had an old well. He plumbed his water out to the front of his property and provided emergency water for approximately 60000 people that lived in the area after the 2011 earthquakes hit. His flow rate was 30 litres per Minute. He got the water tested. It was 15 x more pure than shop bought water!
The bang you usually hear when turning your faucet off real fast is not the pipe expanding, but rather the pipe moving due to the weight of the moving water suddenly coming to a stop, and banging the pipe against something else. This is especially common when there's a long straight run of pipe, like along the basement ceiling, or up the wall to an upper floor that's not well anchored/secured.
Water Hammer
I learned about ram pumps at Ha-Ha Tonka State Park in Missouri. The old tower was up several hundred feet from the spring below. This method was used to supply water to the houses at the top of the cliff. Thanks for the easy explanation!
7:10 - 7:15 That's why I learned as a kid to turn it off not to fast. This sudden change in presure can damage the pipes or at least increase the changange of it getting damaged.
When I was a kid I always liked to turn it on and off really fast to make it sound like a machine gun Kelly

It's water hammer
I've learned about that in my undergrad, as it is widely used in family farms here in Brazil to pump water uphill, the source is a flowing river, and it does really great.
Can they get the water to fill a reservoir and, once full, go higher? (Step and repeat?)
@@JakeWitmer not sure
Yes, but it consumes water to do it.
How much preasure they get
@@asmircar1 I've read it needs about 10psi to operate for a 20ft high (give or take) outlet... don't know about the length of the pipe, tho. But I'm sure there's a paper somewhere that explain it better.
This is how a lot of off grid homesteads get their water to their gardens or to their wells, I fell in love with the simplicity of the Ram pump, eventually I’m going to build one at home when I find an actual use for one

I had read about water ram pumps in engineering school some 45 years back,, and forgot all about it. This summer I visited a manor house in Scotland and those guys had installed a water ram pump 125 years back... so it all came back to me. I am going to make one for myself now.
Thank you for an awesome detailed explanation on how the ram pump works. I learned a lot!
Cool ram pump setup James!

Yep
My grandparents had one of these on their farm to supply water from a creek to a self filling water trough in a barn. I used to love to listen to the clacking almost clock like rhythm of it. I later learned how they worked, but was convinced it was some type of clockwork mechanism when younger, because of that click clack rhythm.

smart grand parents 👍🙏
Thank you for explaining it so well. I watched several video's on how to build a ram pump and they didn't go into the actual physics of it like you did. You made me understand it. 😊
If you put a tank (with an air hole in the top of it) on the waste valve it eventually collects enough water to increase the pressure backwards & puts a small amount of water back into the system that again increases pressure.
You can multiply this setup & also use higher pressure valves to get a head height to unimaginable levels.
I currently am pumping up 100 metres using a tripple setup that is only running on 19mm piping. It delivers approx 200 litres per day.
It cost me $41.32 in total & has been running for over 5 years
wow...
That's serious and what is the maintainance like and do you have to manually open and shot the system down everyday or does it run 24/7
Would you say an oversized version of this could be used in an application that requires pumping water up 600m?
Do you have any videos . Would love to check that out
Please sir, will you share a video of it with us? Could build a generator with it and run basic systems in the house with it. Technology to free us is out there, but it is denied to us by slavers. Please teach us how to build freedom!
4:20 = This is analogous to self oscillating "boost converter" (in power electronics topology). The top valve is the MOSFET, water flow is the current and bottom valve is the diode. Like a boost converter provides higher voltage at output, in the same way, this hydraulic circuit can provide water at a higher point.
But where is the wasted energy in this analogy like the water that exits the top (outlet) valve? Power losses of diode and mosfet?
@@Halolaloo "Wasted" water stands for current consumed from the low level input, this current is higher than the current produced at the high level output (boost converter - height is voltage). It's not wasted but necessary to generate the boost effect. Wasted energy is the water heating in pipes friction.
I have tried so hard to understand ram pumps for months I swear, watching various videos here and there, but this demonstration shows it very simply and it totally makes sense now! Thank you!
There is a guy on TH-cam named Seth Johnson. His channel is called Land to House. If you want to know more, I recommend checking his channel out. He does all kinds of experiments with them as well as showing you how to build them. He even sells them pre-built for cheaper than I was able to find all the parts myself. I have been using one of his ram pumps for about 2 years to keep fresh water to my goats and chickens.
@@Kenyon7877 Funny you mention it, because it was his ram pump that was used in this video!
The ram pump trades volume for pressure like so many other machines, including lift on the airplane wing. You can always achieve higher pressure/force by trading a larger distance/mass/volume.
I'm in Vanuatu at the moment teaching some development things and a request came re Hydraulic pumping. This guys basic teaching is so necessary in these location. Thanks for making it plan.
Sometimes it's crazy how these kind of things are so simple, yet I've never heard of them. This channel has brought a lot of relatively intuitive things to light for me
We just don't run the experiments or we would come to know some of this on our own. But I feel you I watched how a engine works and it made alot of sense
lol, one useful benefit of taking physics classes in college is that anytime someone suggests to you that something they have is a violation of the 2nd law of thermodynamics, you instantly know IT AIN'T.
True but it would be great if we could so that's why it's so tempting for people to believe it
All these physics laws continue to be the buzzkill to any of our ideas, not just free energy perpetual motion power plant, it also applies to our hoverboard.
It does not take college physics to know he needs to continuedly add water or it will stop since water is leaking all down his driveway and down the street.
You don't need to go to college to learn that
*"THERE IS NO FREE ENERGY DEVICE!!!"*
- ElectroBoom
What is the sun?
Not free, we catch and convert. Yet the sun is depleting. You get 'free' energy. But the sun burns, and one day, it will burn out. Same with the water, the water source runs out. You can catch them waste and repurpose it. You can re-add it to the original source. Now you are expending energy. In any free energy generator, their is a source that depletes. The depletion time might just be 10 years. You do not create energy. You transform it. For every volt and amp you get out, you lose it elsewhere. If youmdraw from the greatest power source of all, the earth, the earth also has a shelve life. It also has a limit to its energy creation. You can build more complex machines, add more than one law of physics together to 'negate' aspects of physics, yet you can not change physics, just manipulate it using physics. And all these complex machines you build, most likely these systems already exist in nature. Changing one form of energy into another and keeping the cuycle going is a part of nature. Yet one day, nature will have nothing left to give. Evolution theory and science combined. Nothing could not explode and create a universe if energy can not be created. If a planet or space or the universe is eternal, it would mean that energy is coming from an outside source. Replenishing what has been used. Natural systems might be eternal, converting energy in several ways that lead back to the original source, but wear and tear breaks the mechanisms of the system. Somewhere , you do lose something. Always. 10 000 years of energy. Which to a man that lives to be 80 looks to be free. Your great great great great grand kids will pay the price. But who cares about them right.
Sun will eventually burn out
An immense limited power source
Engine intakes runners rely on the flowing air in much the same way. As the engine revs faster the column of air in each runner flows faster, then when the intake valve slams shut the air in that runner compresses slightly against it. When the valve opens again the compressed slug of air pushes into the cylinder. Generally, long intake runners aid in low rpm power, short runners for high rpms. A well tuned naturally aspirated engine can actually displace more air than its volume.
Fantastic Video! Thanks for using the Land To House ram pump for your demo.
What a observation xD
Thanks. It wasn't working at first. I had to replace the check valves to get it to work with my setup.
Ok
@@TheActionLab The issue was most likely the clear flexible drive pipe. I know for video purposes it worked to have everything in the frame but its ideal to have at least 25 feet of pvc pipe as the drive pipe. That would allow the normal valves to work correctly.
Still a great demonstration!
@@LandtoHouse In a proper setup the drive pipe sholud be even more rigid than PVC, more like cast iron. The less give in that pipe the higher efficiency of the pump.
Wait! Wait! I know this one: the answer is “No”. A hydraulic ram pump cannot be used as a perpetual motion machine.
LoL🤣🤣🤣
I gotta say humans are great at trying to cheat the laws of physics.
How about my friends dog? She’s actually sprinted 6 miles, and she didn’t slow down the entire time. Like she was running at least 20 mph
@@NotProFishing more like misunderstanding mechanisms and declaring it as deceiving the laws of physics
@@NotProFishing , more like we hate them but forced to obey. We wish perpetual motion gives us free energy as well as a working hoverboard if physics laws do not being buzzkills to all of us.
Oh my goodness, this is a charm! Great explanation, certainly got me subscribed! :D
Always wanted to know how these work! Thanks for explaining!
that bang sound when turning the water off is also made by the free pipe installed in the house. it slams the whole pipe into the woodwork or whatever the building supply is that encases the water pipe. I've watched this happen in some installations.
Yep. That's why we put surge arrestor on end of line

You do big favor for humanity and I am very thankful to you for putting so much effort into your videos
This channel is absolutely amazing ! Thank you!
Heck yeah! More off grid hacks please.
Great video. I feel like letting the relief valve from the pump drain into a bucket and putting the pickup for another pump there. Maybe they could both drain into each other so water isnt wasted.
If you're going to add another pump, be it manual or powered, you might as well use that pump to begin with. Trying to use two of these together in a perpetual loop system won't work. The efficient way to use this system is to source it from a river where the waste goes back into a lower part of the river, diverting some water to crops or whatever you're using it for. That "wasted" water isn't really lost, it's just not yours to keep away from the gravity that drove the machine.
Outstanding video and explanation! Best education and explanation of the Ram pump I have seen on the internet and how a Ram Pump works.....
another amazing lesson, we learn new things we've always wondered about how things happen.
His voice lets you know how nice of a guy he is
I suppose, if you have a method of catching that waste water and manually put it back in the system (regaining mass), it could actually be quite efficient. Great tutorial, thank you.
All you would need is a catch basin,a few more valves and a couple of minutes a day.
...that did feel like important point he didn't bother with.
Thanks for putting this in perspective
Wow. This is actually amazing. I didn’t know something like this is possible
And its missing parts to be perpetuel

Best short instruction video on how RAM pumps work I’ve seen uptill now
These are times when I have grudges towards the Second Law of Thermodynamics.
Thermodynamics, just like any other physics law. It's always a buzzkill to our ideas! Still, where's my hoverboard?! Or a free energy perpetual motion power plant.
@just some guy tired of life , also fusion power, scientists still unable to make it a reality. They made fusion but it's a net loss again, uses tons of power to generate a bit amount of fusion power.
@just some guy tired of life Black holes dissipate so you can't actually make perpetual motion machines...
If we ever break the second law, we will be able to survive the heat death of the universe. Even if we only generate a few joules, that can run something. All I want is for us to break the second law, because then we'll be able to actually live forever, even if it's just digitally.
@@Darenz-cg9zg
I feel you bro. However, the second law is what got this universe from that hot particle soup to what it is now, and why we can create things, so we have to deal with it.
The PVC pipe has the windkessel function, used in early firepumps and also biologically through the elasticity of the aorta. It is used to turn a pulsating flow into a uniform flow, which is better for extinguishing fire and Gas exchange

Your great...could you do one about light through calcite before and after its cut into a prism.its effects and amazing properties and reactions to light ???
Seems like the same sort of thing that happens when one member of a binary is gravitationally captured and its energy transfered to its companion which is ejected at high speed. Here the Waste water is captured gravitationally and spurts with very little residual energy and that energy is transfered to the fluid that remains in the system enabling it to rise higher than its original energy state. Fascinating illustration. Thank you!
Yep, but you have to have the waste valve cycle and flow freely or else it won't work. It is a perfect way to pump from existing rivers and streams.
The waste water energy is not captured, it is wasted energy. The energy that matters is the flowing water. That energy is enough to push a small amount of water higher than the original water source.
You had me at perpetual motion.
Well explained. Thanks
Great video! The one thing I missed is the explanation where the energy (needed to raise the water) comes from. I think it comes from the potential energy of the wasted water.
like all hydropower, the energy comes from Gravity, and falling water.
en.wikipedia.org/wiki/Hydropower
You're right. The water starts with potential energy, which is converted to kinetic energy when it travels downward. That kinetic energy is stolen from the wasted water and then given to the non-wasted water.
@@Paralellex I didn't fully understand til I read your comment. Makes sense now!
Amazing. I wonder if you could use this to recycle water used in a water turbine in a off grid setup kinda like a turbo adding more water pressure through the main line connected to the turbine. Adding small boosts.
You wouldn't be able to get any additional electricity from the water in any meaningful way, but you'd be able to conserve water, I suppose.
How much head due you need on the input side to make the flap valve ( i am assuming it is a 1 inch valve) work properly ? Your video shows about 6ft.
these are great for camping. you can also use a small low power fountain pump if you dont have a water source like a pond, small pump into the ramp pump and you have the lift you need
Great demo.
The tragedy is how many people we’re going to see insisting in the comments that a few ‘simple’ adjustments will result in genuine perpetual motion.
Update: I’ve counted five so far!
Would the water evaporate or go outside the ladder if you left over time
Simple just have multiple setups and the waste water from one will fill the other, have the water run down a mill on the way and boom, power.
@@maryann2628 Evaporation uses energy - effectively solar.
@@adambrackston3471 The energy comes from the difference between the water falling to the ground and the water being lifted. Multiple setups just uses more water.
I have a degree in chemical engineering, and I've surprisingly never heard of this. Excellent video and explanation. Love the content!
It stumped me for a minute too... but the original water source has to be ABOVE the Ram pump... and not each cycle loses water through the waste valve... there is no violation of the 2nd Law... it's being powered by gravity... you lose water ... if you have a natural endless source of water... then no worries.. but if you're trying to move 100 gallons up a hill... you'll end up with 30 or so gallons at the top of the hill and 70 gallons waste water on the floor beside your Ram Pump.
@@calendarcalendar3838 but is there no way to direct that wasted water back into the system? i think this is pretty cool stuff
@@woshua3143Nope, the best you could do is collect the waste water and manually move it back up to the level of the source water. Because the waste water valve has to be lower than the source of the water, you can't conserve the waste water and put it back in the system without expending energy.
That's why this is best suited to a situation where you have a spring or a river (a constant source of water) where your can place this valve lower than that source (either in the ground or downstream). Otherwise you might as well use a hand pump up to a water tower or something if you want a system with no water waste.
@@isaacholzwarthwith a water wheel up the top and some gears/ratio.
@@davidvickers8425 isn't possible. The kinetic/potential evergy of the water coming out isn't enough to bring the lower water up. The best you might be able to do is to move SOME of the waste water back up. However, the amount of water that goes out the waste is much more than the water coming out the top, so the energy in the water coming out the top simply isn't enough to move all the waste water back up. It's simply not possible.
you could add tubes with floatiing balls to ad dinline pressure, once you build negative pressure in vertical tubes you have a pressurized system from down up
Hello Actionlab, Great video!
Just wondering, when was this process discovered?
Thank you and have a nice day
John Whitehurst from Congleton in Cheshire invented a "pulser pump" in 1772. Modern ram pumps use the same principals but different materials and configurations.

more importantly is what problem or challenge did it solve or what was it used for.
The hydraulic approach has never appealed to me as much as some of the magnetic ones for attempting the impossible, but I think this illustrates how messing around with an impossible dream might lead to something possible and useful in certain situations.
but doesn't a magnetic pump require power?
@@roadstwotravel1539 Who said anything about a pump? I'm talking about a completely different setup, where you use magnets, gravity, and momentum, plus a design which disengages the magnetic effect at the right time... of course, perpetual motion is impossible, I'm just saying it's fun to play with magnets and things and see what happens.
@@TubeNotMe nothing stops you from combining all to hit your target
@@onekycarscanners6002 yeah, it is all for fun and seeing what happens, we all know perpetual motion is impossible. But the more stuff you throw in, the more fun, and sometimes it seems close, and maybe something interesting will happen.

If you make a ram pump you'll be very lucky if it works first time because they're very fiddly to get going properly, but the plus side is that once they're set up they can run for years without any intervention at all except for cleaning. I set one up in 1991 and it's still working with all original parts.

Every day is a school day. Great video! Often wondered if the water pressure from an elevated rainwater harvesting tank could run something like this 🤔 Ultimately it will run out, but then it rains a lot where I am
I'm working on something just like this. Rainwater catchment tanks running to a ram pump to move the water to top of a gutter which then goes back into the rain catchment tanks.
If and when I figure that out I will add in a waterwheel/flywheel to spin alternator/generator 24/7 which will then charge batteries.

Fascinating!
I could see this being used in pump-storage hydro power.
Probably not. ram pumps are very inefficient so they's only pump a fraction of each release of water back up to the tank. They might work as a supplementary system to somewhat reduce required pump energy but between embodied energy and cost of installation they're probably not worth the trouble.
@@mikekelly5869 What your saying with so much authority is so wrong. How can you say something that has a zero cost of energy production will not make a good hydropower station your years at Shell Mobil and Bp has clouded your thinking.
If you produce energy for free for 1hr a day what's wrong with that. You can add storage tanks to stretch it to 10hrs which is good enough as wind and use low rpm generators but you must be close to endless supply of water and return all water back That's why I call it a mobile Dam can be setup and dismantles as the need arrise
only a friendly comment ✌️
@@onekycarscanners6002 I'm afraid you're missing the point. Ram pumps can be used to make a loop. It's not perpetual motion because (a) energy is added by gravity and (b) only a small portion of the water is pumped back up to the source point. If a tank is used as a source it would quickly run dry and if a water source like a main or a river is used to top up the tank it would be several hundred percent more efficient to run the source water directly through a generator and forget about pumping in a loop. Learn some physics before having a pop at me. Maybe try again in a few years.
This was great. Maybe the best video I've seen you make so far. Very interesting!
The answer to every yes/no question that includes the term "perpetual motion" but not "impossible" is "no."
That still leaves some options for formulating a negative question, like "Will i fail to build a perpetual motion machine?"
I'd say the answer is "it won't work".
Perpetual motion machines do exists.

@@Llortnerof The ISS, Voyager probes, the Earth....any object in motion as per Newton's first law.

Something few realise, even deep space isn't truly empty. There's stray atoms at extremely low concentrations that will ultimately still cause things to slow down through drag or impact. It just happens at astronomical timescales

The bang you usually hear when shutting off the water abruptly is the pipe banging against the walls and mounts, due to the momentum of the water in the pipe.
Not an expansion and collapse of the pipes.
If you look at your connectors in the walls you will see wear and tear where the pipe will slam into the structure
Or if your lucky enough to have exposed pipes in your house you will see them slam forward and wobble around after the water stops.
Exactly. You can even see it in a real ram pump set up on a river. Same thing, the pipes will vibrate every time the waste valve cycles closed. And if you set up the pump and didn't secure the pipes then it will allow it to vibrate too much and you lose that energy into moving the pipes all over hell. Securing the pipes in the setup will give you more energy into pumping water instead of slapping pipes all over the ground and rocks.
@@TheRebelmanone 👍👍
How does the pipe move in the first place to make it bang into the wall stud or bracket? The pipe expands in length,(straightens) then contracts, allowing the pipe to flex, his explanation stands correct. 30 yrs working with hydraulic lifts.
@@nssherlock4547 this 👏🏻🙌🏻
@@nssherlock4547 No. He's talking about the pipe shifting because of the force of the water, not "expansion and contraction". It can eliminated by removing any angles over 45 degrees or manipulating the direction of flow.
I always wanted to build such a pump... it's similar to the boost converter used for DC to DC step-up. ..I know now it already exists😐
Clear Explanation, Thank you very much
I love this channel. One of my top 3.
7:15 Water hammer and the loud "bang" doesn't happen because of the pipes expanding and contracting, it happens because the fast flowing liquid suddenly has to slam to a stop when a valve on the pipeline closes too quickly. Water hammer and the "bangs" occur in the bends of pipes and against the valves themselves. (I've studied this stuff and have worked at power plants)
Water hammer has nothing to do with the "pressure" it only has to do with the "velocity". That's why you get really loud bangs in pipes carrying high pressure steam when there is condensation, because the tiny water droplets get an insane amount of speed thanks to the steam, and the liquid can not turn as easily in the bends, which leads to it slamming into the "walls" of the pipes on bends.
Basically, the way ya worded it sounded a bit wrong!
Thanks for the input. I agree that the main component in the equations is the velocity since we are dealing with kinetic energy. And the banging sound is more from the sound of the pipes wiggling around than the pressure wave. But you can't really talk about why water hammer happens without a pressure wave.
@@TheActionLab err...you are splitting two things up when you shouldn't. the pressure wave occurs within the fluid due to the sudden stop in pressure with no place for it to go..no relief. they shouldn't be treated as two different phenomena. they have pressure regulators and stuff you can install to keep this from happening. should be no more than 55 to 60 psi in regular household plumbing
@@TheActionLab Np, maybe I'm over complicating the explanation... Basically, water hammer and it's bang is a product of the velocity of a fluid in a pipe going from *some amount* to 0, which in turn is a product of the pressure difference between 2 inputs/outputs! :D
I just got very caught up on the wording of the, (and I'm paraphrasing here): "-the bang comes because of the pipes expanding/contracting", when that really isn't the case (except for in extreme cases)!
What you say about how water hammer occurs and works etc seems totally right! :D
What if you made the waste water run into another pump leading back into the original container (an do the same for the waste water from that, and so on...). Could you end up with almost no waste water?
One of the best video of RAM pump, now I know how it is made of.
THAT"S SO USEFUL! Obviously the loss of water somehow fuels it, but if you have a lake or something to drain the water back into, that's an ANALOG PUMP with no no electricity!
Loved the video!
Now hook this into a river, pump water up hill, or even up an artificial platform into barrels which properly flow into outlets valves and through small water turbines running down to the water source.
Invest in a proper equipment to transfer and store energy.
You shut your mouff right now
If you had 9 equal distance symmetrical waste valves coming off that one point like rocket booster thrusters then wouldn't it increase the pressure by WAY more but also require more waste water?
Possibly yes. A caveat with that system is if the valves were in line serially, their motions would probably break each other's cycle. If they were in parallel lines, you might have hope of timing them together to prevent backflow. Perhaps with a really controlled setup, you could get continuous flow in the way multiple pistons turn an engine's output.
I'd expect it to be finicky at best, with very limited returns for each added tube contributing to one flow. One line should lead to the smoothest operation and the most transfer without having a lot of help on timing.
An array of entirely separate lines, or just one bigger setup start to finish would probably be many times easier to set up than diverting the input water and bringing it back together.
In a "Correctly contained system" with "wastage harvested and evaporation controlled", heat death would ultimately lie in the wear and tear of the reed valves mechanism
very slow death though
Before I even get started I was wondering if this would work for a fountain to power it's self. let's see if you help me.
... well the waste water is an issue, lets continue to see if this has been solved. thanks for the help, good video.
what would happen if you sent the waste water into another bucket/ramp system that sends the water back to the original bucket? would be cool to see how long the system would stay running for
and on the way down, passes a hydro generator for power
@@CrAzZyTheCodingBoss That would reduce the fluids momentum, and offset somewhere else.
@@CrAzZyTheCodingBoss That is what I'm working on 👍🍀🇺🇲
@@Rizik1986 Same am working on we need a colabo ✌️
Just call it an indirect dam. So you don't need all the special license that goes with the dam you just return the water back to the original source without affecting the water
Imagine you invest in a massive tank with low rpm magnetic alternator like 120rpm. So the pump speed into the massive reservoir equals the exit speed. Bingo you good. A mobile Dam 👍
@@onekycarscanners6002 Hmm this might be just the ticket to make this happen! I been stumped last few weeks trying to figure out the next move. I wanted to use a water ram pump but it simply won't move enough water for what I'm trying to do. An alt with a small pump could work I suppose.
It’d be interesting to know how much electrical energy can be created from inserting a propeller into a pipe of move water; in your waste pipe in the bathtub or the sink.
Assuming you have some sort of a river or spring, necessary for this to be of any practical use, you'd get more energy directly from the river.
well made an well explained!
I figured it out as soon as I saw water coming out at the valve.
Pretty clever
Waiting to see Mehdi aka Mr. Electroboom to say something along the lines of it technically not being free energy. Work must be done to create its flow.
Nothing is free energy, but the flowing water like in a river is already flowing down under the force of gravity. But humans can take some of that energy and use it to push a smaller amount of water uphill. It never was free energy.
Perpetual motion machines may not seem possible, but I'm sure you could make one if it was powered by a teenage boy's right arm
😂😂😂😂😂
Not possible when thermodynamics is its archenemy. Like all physics laws, they're a buzzkill towards any ideas.
Alright nice have a good day
Thanks. Great explanation.
Thanks for your clear explanation,...how sump pump working without electric power source.
I think this would be a great pump for my homestead in the future, thanks for the idea 💡
I wonder what would happen if you put the waste water back into the bucker
You can't because the waste water comes out at a lower point than the bucket. You can't get it up without any external force. That's why perpetual machines are physically impossible.
It would keep going. Like when he put more water in from the mains hose. If you put it back by hand, the action of you lifting that water UP to the bucket would charge up the system to keep going.
Hmm.. well he basically explained this at the end of the video, how sensitive this setup is, especially the calibration of the pressure on the waste valve. Which would increase if you start to stack up the waste water in a pipe towards the bucket, until it just stops pretty much like the very first showcase.
Thanks for the great video! Do you know if this pump can be scaled up to the size of a small pond? (e.g., 2x2 m) Have you tried to scale it up? Thanks again!
I had the same question, watching this video.
Great video. Useful in my research for a 'green' garden water feature.
