- Protecting our 12 KW Home backup energy from CME (Coronal Mass Ejection) from the Sun and/or EMP with 2 x 2 lumber, aluminum window screening, some galvanized duct metal and some roofing nails. This box should offer a degree of protection that will allow the generator to function should there be an energy burst that would disable an unprotected generator.
This was the BEST explanation of a faraday cage on a generator I have seen to date. Well Done!! Jim J.
Yes! Thank You
If we're attacked with an EMP strike, where will you get fuel for the generator?
I have the same generator and I need something more accessible. We have power outages here so I can't just lock it away.

Siphon fuel out of the millions of abandoned dead modern vehicles and from the no longer open gas station underground tanks (assuming you figure out how to get it out).
EMP or not, this 'cage' will keep the critters out too! Recently my generator failed to run on propane until I found the problem: insects had built a nest of something inside the propane hose's tiny opening which stopped the propane from reaching the unit sufficiently to run it. I can tell you, the screen mesh alone would have prevented that.
thanks for the warning. going to seal the hose with a heavy duty ziplock bag
Spiders are especially attracted to the propane smell and can nest inside the lines webbing them closed.
This has me thinking. It wouldn't take much to turn a regular garden shed into a big Faraday cage. Just line the floor, walls, and ceiling with this screening. Run a 4g copper wire to a grounding stake and Bob's yer uncle. They sell 100 ft rolls of the screen for not too much money. I think the only puzzler would be the door. It would have to seal the gap when the door is closed, but I'm sure there's a workaround that's not too complicated.
This is a great idea. Thanks for the inspiration.
Don’t ground it… that defeats the purpose.
you might be able to use metal duct tape used by ac installers
That's my plan. I have an 8x6 that I want make an entire cage out of
Thanks for doing the test with the radio. Very impressive, nice work!
Absolutely fascinating and brilliant. This is EXACTLY what I've been looking for thank you. Subsequently I am now subscribed, bell rung, commented, upvoted, liked, shared .... may the algorithm gods smile favorably upon your channel friend. Well done. So well done, just fantastic.
Bout time someone did it right. Make sure there's an insulator between the generator and the bottom mat. Square of plywood will do it. As for the garbage can, put a phone inside and call it. I had to close the lid on a strip of mesh to get it to make a good contact with the can before mine would block the cell phone.
The insulator between the generator and mat: wasn’t that what the “folded 5 times aluminum mesh” on the bottom of the cage was for?
Is the plywood really necessary?
@@debragarrett5110 You need to insulate whatever's inside the faraday cage from the cage itself, otherwise you're just completing a circuit.
Well done, especially the radio test. That was awesome! 😎 My next project. Thank you!!
Yes one of the best how to videos too! :) I really liked the generator Faraday cage simple and cool!
That is excellent. Building the same now for my generator ... Thanks for the video 👍
Great design!
Very impressive work. My compliments!
Awesome video! I have a Jackery solar battery backup system i have been wanting to protect but most of the information about faraday cages is pure garbage, this is great!
Exactly what I was looking for. Thanks for sharing!
If you had an unlimited budget, how would you improve this cage and why? Would thicker mesh be better, or rebar? Would solid metal walls be better? Would even thicker metal walls be better than that?
How confident are you that this will protect against EMP?
Very informative video, thank you!
No one knows for certain what an EMP will do to electronics.
Nor what to do to protect themselves from an EMP, other than digging a very deep hole under mountains.
Not even the governments that would do such a thing to other nations.
Perfect video and explanation! You just saved me from purchasing one of those expensive faraday generator bags! AND I'll be able to store items on top too.😎 Thank you so much for sharing!!!
Next, the house.......😂
Wow. Thank you ever so much. I'm doing this immediately. God bless you 💙🙏
Do you have a set of instructions relating to the construction of your generator faraday cage? (A detailed step by step construction setup and list of materials used)
This was an excellent build and test, thank you
All the engineers I’ve read stated you are suppose to solid aluminum. Screening has holes. I saw a simulation. EMP moves trying to get through to penetrate. Great idea but I would use your frame but put the 4x6 sheets of exterior insulation it has very thick aluminum on each side and 1” of solid foam insulation inside. They state aluminum then a buffer like paper foam etc and then your product. EMP tries to enter top bottom and sides. Just a thought. The insulation sheets are 7.00. Cheap. Have lined plastic totes works great. Use the aluminum hvac tape to secure corners.
I just built one mostly based on your design. I got the same results with stopping radio, but not with a cell phone. I’ve done a little research with mixed results about that. Shouldn’t the cage also stop the signal to a cell phone?
Exactly??? Cell phones run on Giga Hertz Frequencies which is like a Microwave? Faraday cages "should" stop these frequencies also?
My husband JUST built one using this exact design and laughed at me when I called his phone that was inside the cage. Hes like “thanks for wasting my entire day for nothing” 😢 sigh… guess I have to figure out something else now. I am not looking forward to spending $1000 on a bag.
Dont forget to faraday protect those solar panels for your Jackery.
Exactly what I was needing. Thank you! I'm making one very similar.
Thank you. Great video; very helpful. There are many sites trying to get people to buy expensive bags, copper mesh, etc. I was looking for recommendations on hardware store price-point protection. So I really appreciated this. But could I request that in the future you don't keep walking around? Thanks
So draping a faraday blanket over my generator won’t kill some electrical interference my generator is putting out? It needs to be sealed essentially
Very Impressive! Thanks!
Question. EMP is not radio waves. A single powerline can stop an AM signal. Did you test Bluetooth or GPS signals under this cage. I made a small bag for my key fob and I tested how much aluminum it took to stop the signal. 1 wrap of aluminum did nothing. 2 wraps of aluminum blocked some cellular. It took 3 wraps to stop Bluetooth and GPS signals. I only mention this because it looks "too simple" to prevent high powered magnetic waves from reaching the inside. Similarly to a microwave oven some waves still come out through the screened glass window.
Nice is the aluminum screen one layer all the way around or 5 . ?
Thanks for posting this I did the same project following your video
Well I need to build a garage like this.
Quick question please...we made one and it is great. The radio signal is blocked, but I was just wondering about the cell phone signal getting through. Does that matter or is generator still EMP safe? Thanks for the video!
Hi, where do you buy the aluminum window screening mesh? The ones I'm finding on Amazon are for insects and such.
EMP has happened and it is time to drag the generator out of the garage and start it up. Can I start and use the generator inside of the EMP Faraday cage? Will the electrical cord void the Faraday cage. Will I have to buy a EMP shield device to protect the generator? Can I run and receive power from the generator with the EMP shield?
I’m working on building this now. Thank you so much for this video. I’ve been watching it over and over to get it right. So far so good. What did you attach the aluminum mesh with? Can I use a staple gun?
Yes, that is what I used, Make you overlaps at any seams as large as possible. Leave no open air gaps.
@@innovativeoutdoorsman5067 thank you this solution is going to save me a lot of money. Great Video
@@innovativeoutdoorsman5067do i need to lay down a piece of plywood at the bottom? Or can my generator and other objects sit right on top of the aluminum screen?
You need to insulate. Some use cardboard if indoors
@innovative Outdoorsman What about your solar panels. Don't you need to protect those too?
I have the same generator, do you not exercise it as recommended?
Thanks for the video.
EMP is much different from radio waves electro magnetic pulse hopefully it will help you!
Excellent. Thank you!
Very nicely done
Great job , would copper be even better ?
Where can I find this aluminum mesh? Is there a brand name or model number?
I had a pacemaker implanted and the Dr. said I couldn't work on my motorcycle, motor not running, because of the magnets used for the ignition system. I'm trying to create some sort of faraday device to I can do some minor work. Any suggestions would be great.
What is your plan to attach power? Do you have a way to do that without risking EMP issues?
Doesn't it need an earth ground for an EMP other than sitting on the ground? Nice job on the build. by the way. One more project to put on the bucket list 😁
Doesn't need grounded
I had asked if you have to ground the Faraday cage and the other thing is what do you put underneath between the ground surface and the cage itself a piece of wood with rubber a piece of metal cuz it can't be on the ground Yes explain
Nice, is the mat one layer or several
If I'm not going to store anything on the top, is the galvanized ducting necessary for protecting the generator from EMP?
no but it protects the screen
@@innovativeoutdoorsman5067 Got it. So I could just lay a piece of plywood on the top.
But won't an emp mess every else up like the house so this wouldn't run anything.
Have you tested the effectiveness of the generator cage yet?
Cool. I was unsure it would work, but awesome. Why are you not putting it to use now?
It will cover the generator at all times (until I need to use the generator)
So I understand wanting to protect a generator. Wouldn't you need a far away cage for whatever electronics you want to plug into it? Otherwise whats the point?
water well!
Those guns are so loud. Can we insulate as well? 96 dbi
This is pretty awesome...Thx
Don't emp proof a generator unless you only plan on charging batteries inside the box with the generator because emf can travel down a wire. But if you use alternative sources of power such as liquid wires and permanent magnets it's way more expensive per watt but water can't melt or get hotter than 100c and permanent magnets arnt destroyed by emf so a generator can be made emp proof and a network can also be emp proof using fiber optics to send data in and out and you could just get air powered engine that's emp proof and can charge a air tank to store power like batteries and can work without fuel you just need air pressure and you can get that with any method like use chemistry like acid and trash or bio method like yeast and garden trimmings cuttings slow production but constant CO2 or just use a air pump
WTF?
Ok Im confused here? Aluminum screening has tiny air gaps right? Your telling me electrons cant penetrate them? and cause damage to the generators electronic components??? Someone please explain this thanks
Ground the cage to earth. See what that does for you. Also don't set the phone directly on the mesh. It needs to be insulated.
I'm really getting tired of telling everyone that if your Faraday cage isn't grounded it's just a capacitor with no way to discharge when bombarded by electrons, inhibiting RF means nothing!
That's one of the biggest misconceptions about faraday cages, no, they do not need to be grounded, they just need to be fully encapsulated.
🤣🤣🤣🤣🤣🤣🤣🤣🤣
OK, you're getting really tired. So give it a rest.
wonder if 1 inch by 1 inch mesh screen too large. makes sense that the smaller the better
Hey thanks for the video!! I just got done building mine just like yours. I do not have an fm radio to test but when I put a gmrs radio in the cage it still receives the signal fine. I know the frequency is 462.575. Would you happen to know if gmrs signal gets through on yours? Thanks again!
A faraday cage doesn't "block" signal, it attenuates it. How much attenuation you get depends on how well the cage is built, but standing right next to the cage with a strong transmitter is likely to get enough signal through to be heard. You might 60 - 70 db of attenuation with the window screen. To get more, you'd have to build a second cage bigger than the first one and put it inside of it, like one of those russian dolls while making sure they are not touching each other.
It's also possible the antenna in the handheld was capacitively coupling with the wire mesh if you were really close by, in effect turning your cage into another antenna for the radio. So try backing up a bit, maybe 20 feet, and try again.
@@andrewscharbarth2099 thanks for the info! Yeah after I posted that I watched some videos from Emp Dr who said the same thing. I know I built it well enough so I’m just gonna call it good. I do see w a cell phone inside that as soon as I drop the cage down I lose all my wifi networks, then a few but not all come back, so I’m believing it’s a good “seal”.
Any chance you direction on how you constructed the framework?
I made my own box and am using an app that came with a faraday bag I bought to test it. My box keeps out cell signal, but not WiFi. Not sure if it matters that WiFi can get though or not. Any thoughts?
Yeah, the mesh is stupid to use
@@braddougherty3401 why? What would make this mesh cage better, and why would it be better? What if the mesh was thicker like fencing wire? Or even thicker like rebar? Or is it better to have a solid metal structure and no air gaps?
Well done!
Very sharp 😊
Nice Show Well Done Thanks 10-4
How does the foil tape work when the sticky backing negates contact?
Do you have to ground a Faraday cage
Thank you, sir.
I've read they can hold a charge if not grounded well, but I don't know...
Should you put your solar panel in a Faraday cage also? Thanks.
no (assume you mean whiles in storage and not in use) No need to do that.
You could sell these for a lot of money. Any chance you would pre-assemble the parts and ship them?
hello there man, very creative idea and execution, can i get an opinion? i m doing a project lasts 2 year on Brazil and i m having a big FUC1N5 problem that is blowing my mind man. Here i have a chemical industry but there s a lots of underground water, so much on some cases it s coming from ground to especial hard ground on basements ... this water is generating a kind of strange EM field arround all area, them my ground condutors are inneficient ... do u think a faraday cage could dissipate back to the ground those strange EM fields?
I am very familiar with this problem, I'm from Wisconsin USA, we are a very large Dairy State, our electrification grid was built in the 1940's and unlike the EU we use mother earth as the Neutral / Ground from the home back to the Electrical Power Station. What you're experiencing is called STRAY VOLTAGE. Somewhere near your home is a power pole that has a cable ground wire going into the ground, that (unused) returned electricity is going from that ground wire ( through your house) back to the generation station. It can cause severe health issues, restless sleep, animals not drinking from metal bowls etc. You can trace the stray voltage source with divining rods and cut the ground wire at the source ( this is very dangerous high voltage and is very illegal, be careful because you could kill yourself). Or? You could be very blessed and live on intersecting LAY LINES. but hopefully I have given you two things to research.
when he lifted the box and the radio started 😯😯
I am getting mixed info about protecting the solar panels. What's your take on the panels? I have 4 aluminum garbage cans, two large and two small. I found cheap plastic garden pots to line the insides. Also used aluminum tape around all handles. taped both inside and out. I was picky about each can's condition at the store. No dents and good seal to begin with. I like your small tins idea for inside the big can. I think the important thing is to attenuate the pulse to a much lower dB to succeed. The trash cans should suffice. Make sure to have a drive loaded with movies for entertainment as well. I have a couple old tablets and laptops protected as well. I just bought two Honda generators because they are much much quieter than others. Don't want to attract attention. I couldn't believe how quite the EU7000i and EU2200i are. They also have Eco mode and use much less fuel than my older units that had one speed to create 60 Hz. The inverters are super clean AC outputs that stay at 60Hz at all loads.
Solar panels and lead acid batteries should not be harmed by an EMP. the problem is with all the electronics, from my research you can purchase EMP hardened solar equipment

I might've missed it but what paint did you use?
DO SOLAR PANELS NEED PROTECTION
Hey is there a way to contact you about this build I'd like to see if I could possibly have you build me one
N you use a 55 gallon barrel lined with cardboard and then your 2000 eu generator wrapped in heavy duty aluminum foil, 2 or 3 layers and then stored inside the cardboard lined 55 gallon barrel for a Faraday cage?
That should work if the lid is metal to metal contact
That should work if the lid is metal to metal contact
That should work if the lid is metal to metal contact
That should work if the lid is metal to metal contact
That should work if the lid is metal to metal contact
So if a emp would happen how do you get fuel for your generator? Inhave about 25 gallons of fuel that I alternate and use fuel stabilizer but how long would fuel last being stored in containers with stabilizer?
Recall it can run on either gas or propane and propane lasts many years. Gas (I rotate my supply) last 2 years with stabil.
@@innovativeoutdoorsman5067 i okay I wasn't aware that gas would last that long!! And my generator runs propane as well. Thank you I appreciate the fast response and I guess I need to stock up on more fuel and propane now 😉👍
@@innovativeoutdoorsman5067 I do the same except I use "marine stabil". I am told it is made to last longer due to marine motors sitting for long periods.
An EMP event is a one time event lasting until the nuclear explosion dissipates over a few minutes. After the explosion you can again access your electronics as needed. The problem is you never know if there is a seconded or third bomb going off a day or week later. That is probably doubtful, but can happen.
What is the purpose of the paint layer? Is it necessary?
it protects the wood.
And folks used to make fun of tin foil hats. Microwave frequency does penetrate the human skull. Protect yourself as well as the equipment
I thank you for the info
Nice Video! Subbed.
Was that aluminum window screen where you buy that at need to build one ASAP thanks
hardware store
All good but aluminum tape not needed
If an EMP happens and your the only guy with a generator running for miles around it wont be a benefit. Also having to source 100’s of gallons of gas a week will be dangerous. A solar generator is the way to go. No noise and can recharge 100’s of times.
HAhahahahaha No. I now live in the middle of nowhere with no neighbors and a quart mile long private driveway into the woods so noise in not an issue and even if it were, its so easily solved. I also have solar but 4 backup generators and lots of propane to run them on (not gas)
Add ferrite cores to the wiring of the generator
why line with cardboard?
no contact with the metal can
@@innovativeoutdoorsman5067 well thats what I thought but the guy that wrote that book, arthrr bradley (?) I watched an intro vid from him and it seemed fine to roll the tinfoil over the box. Plus I watched another with a cage built over a gennie, seemed to block the radio reception fine.. and.. also.. (Im so confused) arthur bradley said "no need to ground".. but I see "emp" as electro magnetic pulse.. (electricity) not a "radio wave".. just what little Ive dealt with industrial power, I would think one needs a well grounded, sealed metal, internally insulated with non conductive material box.. right?? And really, does it matter if the device is off and/or unplugged? Ugh..
couldn't you just build a plywood box and cover it with aluminum foil?
yes, but not as durable as the aluminum screen material.
Yes you can, but don't forget the bottom
Going ‘round and ‘round made me dizzy!
Not bad but I also ground mine and the same with the can
it's not necessary to ground.
If you ground make sure its directly to mother earth NOT a water pipe or electrical panel That would be a big mistake!
im getting dizzy following him running around the generator !!
Anything special about the paint? Anyone?
Dude round and round makes me nauseated stop already
Getting dizzy 🤢
can you please stop circling around and around!
Nice!
