As a suggestion...you make a good presentation and the website provides support on the topics you've discussed, but many of us need plans/know how or product for our vehicles and a faraday cage that can be bought or crafted into various sizes. The information you are providing is more vital than most people know, thanks for helping us out.
I’ve purchased and EMP shunting device for my truck. They are available. As well for homes and many other applications. I’ll be using small bags for small devices. The information her is great.
Wow!!! I just stumbled upon your channel and I'm blown away with the amount of information and details. Thanks for sharing your knowledge and expertise!
Thanks for all of your advice and the information you have provided. I am currently putting up one of those steel sheds as sold by the big box stores. I see, in past responses, that they generally provide 10-15dB protection. My plans are to place the shed of a wooden deck. I will then put metal (roof flashing) over the wood and screw the metal to the walls. Then install wood (plywood) over that. I will use two layers of plywood for strength. I will use aluminum tape over all the seems. I hope (not totally figured this out yet) to install some metal flashing over the door seam so when closed, the majority of the door will be shielded. What would you expect these mods to do regarding EMP protection? I don't expect to store a lot of very sensitive equipment in the shed but every little bit should help. Should the building be grounded to the ground or would this just provide a gateway for the EMP to enter? Thanks again for the information you have provided.
Certainly, these steps would help, but it's hard to say how much. Perhaps you'd end up with 25-30 dB of shielding at the end of it -- just an educated guess though. One thing that can greatly compromise buildings like this is wires running in and out. If you are going to have power (or data) wires pass through the wall of the room, you'll need to take protective steps, like filters or ferrites.
How do you solve the Decay (Dentrite effect) of Lithium battery batteries inside your power supply? In 5 years time after the production , whether you use it or not. The quality or the capacity of those lithium power supply will go downhill. Is the only solution to buy new unit every 5 years?
I watched this, and I've seen other companies with EMP electronic shield boxes you place on wires of your car, house, boat, etc. The beauty of all of these devices is...... if they don't work when an EMP hits, you won't have the tech working to call and complain and ask for your money back........ Nobody can prove their products work until AFTER a real EMP strike. A lab test just can't duplicate what can happen. I hope all of these products work if the need arises.
That true about anything but the fact they have been tested by the US Government and are installed on all their higher missile defense sites, I would think they do work.
Yeah I can't personally test an emp but they absolutely can and have recreated emp pulses in the laboratory and absolutely those expensive little boxes worked. If you believe the US government. The fact that they spent money on something doesn't mean anything. Remember 10,000 dollar hammers and toilet seats listed in the late 90s on the budget? It was even referenced in the movie independence day. Anyway the military claimed they had to shut off in ten one billionth of a second and emp shield did it in 1 in a billionth over and over again. That's the claim at least. I'd say they probably do protect from emp but I wouldn't bet the farm on it.
I have a question: will a solar panel ( from Harbor Freight) that is not hooked up to anything, still get fried in an EMP? Also, so you know of any singles sites for preppers? Hard to find a mate that is on the same path as a prepper/awake person.....just saying
Fantastic presentation! You made the complex very simple to understand, especially with all the baloney that is floating on the internet. Thanks again.
It would offer some shielding, but it's not possible to say how much without taking some measurements. Best guess, maybe 10-15 dB of shielding. That certainly helps.
my shop is such a MESS. I am like W C Fields and know where everything is ,, ,, until I don't, Then I go through an enormous cleanup-straighten up process. I am envious of seeing all the screw drivers in such strict order.
If the whole house surge protector protects against the conductive threat, aren't all your large home appliances still susceptible to the ambient threat? So how could freezers be protected. As a part two to my question, would a typical modern chest freezer, like you could buy at Home Depot with no digital display be susceptible to the ambient threat?
Doc, how could I protect 100 watt solar panels from an EMP? Are there bags big enough to fit a 3'L panel? Or could you make shift a box covered in foil backed duct tape on the inside and out? Would something like this give me enough protection?
You are selling anti-static bags as 'EMP bags'.... On your website..... so I think we know how you earn a crust! People who tell me I need stuff and then offer to sell me some snake-oil are shameless. The inverter you put in that anti-static bag has a 2mm thick metal case.... and you say it needs the protection of 0.1mm of conductive plastic! Simply absurd. DO SOME RESEARCH PEOPLE - learn what a faraday cage is - check out the protection offered by sheet metal compared to mylar and unsubscribe from this charlatanism.
Static bags, and lay a cloth over bigger stuff including cars? As another engineer that’s studied EMP AND SGEMP, are you kidding me? 5000V/m radiated effect won’t be touched,and ferrites won’t do conducted more than what? 20 dB. This is a false sense of security.
Im not sure that you fully understand what an EMP is and how they actually cause damage. Electrostatic bags are fine for reducing radio frequency signals but have zero effect on magnetism. The damage to electronics caused by a an EMP is unique to the type of EMP and is manifested by a fast transitioning extreme intensity magnetic field that has the flux level to generate destructive currents in circuits and wiring (even circuit board tracks) that can damage semiconductors and associated software of many devices. The only true protection for high speed EMP's (Nuclear) is full MU metal shielding... not RF faraday cages and not anti static bags. They are snake oil fixes, an EMP is not RF energy, you need to block magnetism for effective screening.
Spend money on a faraday duffel and keep your power station turned off. I feel like if you really fear for an emp, you just accept it and fork over the money.
Hi, Wondering if you would be willing to repeat your EMP bag shielding effectiveness test at say 10-20 MHz an then share the results with us? The shielding effectiveness as a function of frequency is going to vary depending upon the thickness of the conducting material and the test frequency. There is a big difference in the skin depth thickness required to effectively attenuate a 10-20 MHz signal than it is a 500 MHz signal. It is going to require a much thicker conductor (or one that has some magnetic permeability) to effectively attenuate low frequency signals. E1 EMP signals start becoming much less significant after about 100 MHz. The bulk of the energy is contained between 100 KHz. and 100 MHz.
or do a real test of the radiation inside a 2mm thick faraday cage like that inverter has before and after you put it in one of those bags you sell - which will have no impact on the safety of the inverter.
Just use a bed sheet and drape it over the thing. Put some bricks or rocks to hold it down. Then mark the bedsheet on the outside of the bricks or rocks. Take it all apart and that will give you the size you need.
Multiple turns through the ferrite are much more useful. The impedance if the ferrite increases with the square of the number of turns through the core. So two turns is the equivalent of putting two ferrites on the wires. Four turns in the equivalent of 16 ferrites, etc.
Correct on both accounts. (I see I made an error-- yes, you are right on that, 2 turns in equivalent to 4 ferrites) However, note that the saturation only applies to common mode current, not the the differential mode flowing in the cables. This should be relatively low, as it is what you are trying to get rid of anyway. @@HelloThere-nz9ld
For my whole house generator the cloth would not work because it needs to run once a week for test. I built a 2 inch square wooden frame that fits over the generator and covered with aluminum mesh...expensive. Then I covered with aluminum screen to be sure. Next is a tarp to keep out rain but vents clear. Grounded to 6 foot iron bar. So far, no EMP but hopefully will stand up. Have surge protector on inside panel with three ferrits on incoming cables. Hope this helps.
Interesting. Almost completely useless, like most of the obsession with EMP I've come across in the past, but he actually has quite a few more clues about electromagnetics than most. Trained high power RF Transmitter Tech here. We also did lightning protection for buildings on mountaintops.
Been putting some thought into this for obvious reasons. I honestly believe if everything falls apart anyone who depends on these kind of amenities won't make it. It's either survive without power or die
@Adam Craig they won't be worth a damn either after a short while. Honestly I think the only option is get your heart right with God. Accept his sacrifice and debt paid and go on home with him when that day comes. "He who loves his life will lose it"
@@normahepburn1643 wrong, they have studied this quite a bit and criminal types do this, not civil people. Civil society existed well before our currnt use of electricity.
@@whummer98 its nice to think civil people would not resort to this behaviour but when push comes to shove civility goes out the window especially if you have little mouths to feed and care for. Civil people acted like animals over toilet paper during covid, imagine if there is a food shortage.
What's your opinion on ebayers selling military grade conductive cloth thats 39 x 42 inches for about 12.00 dollars. Heard anything good or bad about their conductive cloth? Love your UA-cam vids. Thanks.
My understanding is that free-standing solar panels are not very susceptible, so covering may not be required. Once they're connected to cables, they become susceptible, however, and would require ferrites on the power wires. I talk about this in a video I did on protecting solar power generation systems.
I have a question. I have a 40x9 steel shipping container with a wood floor. I have nothing touching the walls for 6 inches all the way around. Can I store stuff safely in it? Great content by the way.
Always great videos! What type of thread would you recommend for sewing your EMP cloth? Also, does the Siemens FS140 go into the fuse box panel or just on the outside meter? PS. Would you recommend using desiccant pouches to absorb moisture for long term storage of electronics in your EMP Bags?
Any thread works fine. I've tried regular and conductive thread, both worked fine. As for the Siemens FS140, it can go outside the home, inside and mounted beside the panel, or inside the panel itself, depending on if you have room inside the panel. If it's outside in the elements, they sell a weatherproofing enclosure for it.
@@disasterprepper Will EMP take out solar panels? I know they have blocking diode that will need to be replaced... But what about the solar cells made of silicon?
Hi Dr. Bradley, great video thank you so much. I have two questions. One: you state that Lithium batteries do not like to be fully charged. I have two Jackery solar battery generators with lithium batteries. I usually keep them fully charged for emergencies. Should I not be doing this? Two: you mention batteries with cables that are connected could be damaged. Does this include automobile batteries that are still in cars if the car is turned off. I realize that most all cars now have a trickle draw because of clocks etc. would these batteries be affected? If so, would connecting a high saturation ferrite to each cable coming off the battery protect it ? Thank you again for all the work you put into your videos. I am learning so much, almost feels like my college days, just wonderful.
In general lithium ion rechargeable batteries shouldn't be kept fully charged as it shortens their life. You can read more on the web at places like batteryuniversity.com/index.php/en/learn/article/how_to_prolong_lithium_based_batteries/subscribe_thx. As for batteries with cables, it is really the connection to the grid (or very long conductors) that cause enough energy to come in and damage batteries. Cars are very complex electronic assemblies, and the only way I've ever found to fully protect them is to cover them with something conductive when not in use. Some people do put ferrites or other protective devices on their car battery cables, but unless the ferrites were high saturation, they would just saturate quickly.
@@disasterprepper Thank you Dr. Bradley. I will check out the web page you suggest. I was thinking of the ferrite for the batteries not the whole car. I figure if I can save damage to the batteries I can use them with my little inverter for power.
@@hummingwind8869 Ah, sorry, I misunderstood your question. Ferrites placed on the battery terminals could indeed help the battery to survive - assuming the high frequency energy was enough to damage it.
Wonderful info! 2 questions: 1) I have a similar power generator that would use solar panels. What protection would I do for the connection from that setup? 2) Ben over at Suspicious Observers is stating we’ll lose our geomagnetic protection from the Sun soon. If and when we have a CME there won’t be just one emp, but constant emp threat from the sun for thousands of years. How do I protect my solar backup etc when it’s possibly going to be energized threats several timers per week? Especially when I can’t detect when it’s safe to run something? Thanks ahead of time!
Small power generators can either be put in EMP bags, a Faraday cage, or wrapped with conductive cloth. I would also recommend using one of the T.R.A.P. transient suppression devices (see disasterpreparer.com/product/generator-inverter-protection/). As for our planet losing its protections, I assume that's being said due to the recent movement of our magnetic poles. Personally, I think it's much too early to draw any conclusions on that right now.
I am building a house and have installed lightning rods. Do they help or inhibit EMP protection? Also, does underground wiring in non-conductive conduit still act as an antenna for an EMP?
Any wire is an antenna for lightning /EMP. The critical factor is how much energy can it collect. Just regular post and wire fences can pick up a surprising amount of energy, but burying stuff in the ground will protect it to some degree. Stuff that is disconnected is pretty safe without any wrappings or special treatment. That includes cars.
I watched some of your earlier videos when you were making foil boxes in your kitchen I think. I just never did do anything, fooling around over 12 years and now here I am trying to get my husband to look at your videos too. Thanks so much for all your knowledge. We purchased a GENERAC whole house generator and finally got it installed last December. The people set it up to test once a month, so I can’t really cover it up with anything. Also it clicks on in seconds when power goes off, so if I make a cover for it and I am away I ruin the system. Q#1: Is there any method of building a screen wire cage over the GENERAC! I could disguise it some how and allow air flow? Q#2: Which of your books would be the best to start out with as I try to build or learn to block the current? I purchased “The Survivalist” yesterday but it has not arrived yet. I purchased 6, galvanized steel, trash, cans, a year ago and still have not done anything with them. My husband had not watched any of your videos and two days ago he told me he put his spare CB radios in one of the trash cans. So even he is taking notice. I had to tell him he just can’t stick stuff in the can! Lol
Hey if you want those cans to work you need to insulate the inside or cover what ever you put in with newspaper. If they directly touch Metal to metal the currant will run into the electronics.
@@fajile5109 yes, I understood this from watching videos but afraid my hubby didn’t. So, we have to get some foam and cardboard to line the inside of trash cans.
From my understanding anything that allows air flow will also allow the EMP waves to get in... My suggestion would be to cover your generator and turn the breaker to that generator off while it is covered... You should have a breaker for that generator before it goes into you whole house baker box...
Check out EMP Shield. Small devices, about the size of a plastic electrical house switch box, you can add to your house, cars, generator, solar system, etc. You can usually find a $50 code from many youtubers. I used Reality Survival. Mention them for $50 off each device!
My solar generator is being stored in a carpeted closet…does carpet have any conductive characteristics where I would need to completely wrap my generator, or would I be good w/ draping EMP cloth over it while it sits on carpet?
Thanks for the guidance. Surviving with my survival tools is ideal. Worried about those without who take my tools. There is always a bigger stick than mine. No food, wildlife first to go, then zombie apocalypse. Best to just dig a hole, bury everything in steel garbage cans.
I watched your presentation about using a garbage can. Problem is I need 20 “ at bottem to store generator. Can’t find can larger than 17 1/2? Tell me, where did you find one big enough?
It appears that a clever electrical engineer (whose brother is a carpenter) may together be able to build an EMP-proof "box" around a large (24kwh in my case) Generac Standby generator. (I think that option is likely far too expensive even if I could find someone qualified to do it!). So, could you comment on the "EMP Shield" (brand name), which is available everywhere to install in cars, homes, etc. Do they work, and how well? They've doubled in price in the past couple of years and are too expensive an option if the answer is any version of "it depends." Thanks in advance from a new subscriber.
I bought a small Honda generator and it is still in the box. If I wrapped the box in two layers of heavy duty aluminum foil, sealing the seams with foil tape (as used on heat pipe insulation) would that get me close to the 50db rating I need?
EMP shield sells protection kits for vehicles and generators that are based on the models they sell the military. Another alternative. Here in Oklahoma we just had several days with sustained winds above 40 MPH. Laying a cloth over something outside isn’t a workable option. It would end up in the next state by days end.
GDT (gas discharge tube) and an MOV (metal oxide varistor). Use both in tandem and that should give enough protection. Connect one end on the positive and one end on the negative.
I have a couple of questions, but I would 1st like to start by saying that I love all of your books and I have them all on audible. If you disconnect your battery from your automobile do you think that an EMP or a CME would still have an effect on it? My 2nd question is will you be making a 13th book and your survivalist series?
If the battery is disconnected, the battery itself would be unaffected by an EMP, however, the car's electronics could still be affected. The energy couples into the cable harnesses and generates potentially dangerous voltages and currents. As for the 13th book, I probably will write another in time. Right now, I'm finishing my new book, "The Watchman." It's very similar in style to the Survivalist books. You might give it a try. It's currently for pre-order at www.amazon.com/Watchman-Arthur-Bradley-ebook/dp/B08FRQ9H7T
Hi I hope someone responds! We live in Minnesota. I was going to get a 10-20 gallon garbage can to make a cage out of. But, after I got to thinking about it one night in bed, I thought we should get something bigger, as I think it would be beneficial to put our king size electric blanket in there with a portable generator and solar panels. Would a faraday cage protect an electric blanket? In theory I think it would. Thanks for all your help!
I know a old Cold war veteran about 80 years old. He was a technician that fired the honest John missiles from Greece into Soviet Russia. He said straight up and EMP pulse will knock out your batteries. He did say they can be recharged if your car had a generator but he said an alternator would also be fried. Of course. He's not trying to sell anybody anything so where the hell does his old man know?

@@disasterprepper my pole barn has steel roof and exterior walls. Inside steel ceilings and walls. Doors are all steel. Will the pole barn give any protection in a Carrington event scenario? If I were to ground all sheet metal to each other and ground would this help
How about sealing our garages from the inside with three layers of aluminum foil? I bet that would protect everything in the garage once an emp is deployed. We'd just have to make sure the area around the door overlaps to maintain the seal after entering and exiting the garage.
Foil can give you a good degree of protection, it tears easily, however, and once it tears it will lose its protection. The bags tend to hold up much better.
Hi, you covered most things but I have one question. I have a solar system (panels, EMP Shield, charge controller, etc) as back up. It is connected to my home through the breaker box with a 40 amp breaker that is switched off, unless it’s in use. If the solar is in use, I shut my main grid breaker off( which also has an EMP Shield on it). How would I protect my solar system since it is connected to the grid system? Have I done enough? After watching this, I’m thinking I could take the 40 amp break out of the breaker box until it’s needed? Thank you, I love the information you give! ❤

Those are not EMP bags. They are standard ESD bags. Electro-Static Discharge bags slowly dissipate electrical energy over time. A lot more common than this guy claims. Amazon.
Doc, great video and advice. Question: I have a 12k backup propane/gas powered generator that I store in the wooden shed. I will connect it to a 50amp box via a 50amp cable (10 circuits) that feeds into my regular panel that has a utility transfer switch. >>That said, is the fabric cover over top of the generator (unconnected and stored) enough to protect the circuitry in the generator if draped over it and touching the wooden floor? Do I need to encircle the entire generator, as in, will the energy be able to penetrate from under the wooden floor and damage the generator circuits or will it dissipate as it is not touching earth? Do I need to keep the ground wire from the generator permanently attached to the rod that is outside? Second, would I be able to still use the aux box, or, am I outta' luck with that? Thanks so very much. (I live outside DC, so this is a concern). GOD Bless
I have installed a number of EMP Sheilds devices on our power panels, 32KW backup systems and vehicles and farm equipment at our ranch. Have you tested the EMP Sheild products? Are we protected w/this product?
All vehicle computers will be fried. Dead. Kaput. Make a plaster of Paris tent around whatever. Add cut up steel wool for the paranoid? Cover it with glued on quality aluminum foil. Paint to your liking. Maybe $15 bucks total. Keep all of your wiring to a protected minimum. And consider, you might be the only neighbor, with any power. A serious inevitability.
You can probably go to an army surplus store and get a metal box that has a real rubber gasket and locking clamps to seal the lid. Maybe steel ammo cases would work. How about a micro wave oven, working or not. It's a faraday shield. Put your phone, charger, usb cables, laptops, tablet computers and backup hard drives. If we get hit we will be back in the 1850's.
EE here. So what is the mechanism that a lead acid battery would fail due to an EMP????? Electronics(semiconductors) are destroyed due to breakdown voltages, gate breakdown, and/or junction temperature, old tubes didn't have that issue. So lithium batteries with their internal BMS could fail. Also EMP stage 3 induced DC on the grid are not blocked by ferrite beads, deconnection from any long wire(ie the grid) is the only solution to that.
Do you have a method to EMP proof a camper or RV? I use a surge protector from the post to my campers power cord now. Could I put one of your customized ferrites on it around the power cord?
If and when "tarpping" a unit, use a sheet, a blanket, a towel, etc to approximate the size of the shielding cloth needed, then measure said sheet, towel or blanket. I'm unclear on how to protect a portable inverter generator (3300 watts peak X 20 amp output X 60 lbs) that is sitting on a shelve in my garage. Should I buy an extra inverter board and bag it? What about the the magneto, the coils, the LEDs on the control board? Should I build a box? Store it in an aluminum shed? I'm looking for some practical ideas, that I won't need to pull out a second mortgage to accomplish. I'll bet you have some ideas...

Hi Doc. Do any of the silver emp bags you sell big enough to fit a solar panel? I'm trying to find the cheapest possible way to protect my six 100 watt panels. Its so hard to afford things these days. Any help would be great. Thanks.
How about moisture...condensation that might collect inside the bag from long term storage? Could you ground the cloth by clipping an alligator clip to cloth and plug in into a ground outlet on a receptacle in your home?
What am I missing here? The entire Inverter is already encased in Aluminum. Also, why could I not place the devices I want to protect in a metal box or cabinet like my safes?
Why hasn't our government done anything to fortify our power grid, transportation, hospitals etc for EMP? What kind of idiots do we have running this country?
How about a Lincoln Arc Welder. They are tough. do they need any emp protection ? They can run a house in a Emergency ? Of course I mean a diesel on a truck. ?
Perhaps you could explain if something doesn't have an electrical charge to it or the item has been perhaps electrically discharged how is it then susceptible to EMP?
i see so much about emp protection lately. does anyone know what a TEM wave is with suitable subscripts? what permeability is?. I had a could of permalloy once and mentioned it to a few. then a freind seemed to have taken it. are there those who don't like the idea of a good faraday cage? now why would they dislike that? I ask it rehtorically. maybe it's not a good idea to mention if you have a good faraday cage.
As a suggestion...you make a good presentation and the website provides support on the topics you've discussed, but many of us need plans/know how or product for our vehicles and a faraday cage that can be bought or crafted into various sizes.

Thanks for all of your advice and the information you have provided. I am currently putting up one of those steel sheds as sold by the big box stores. I see, in past responses, that they generally provide 10-15dB protection. My plans are to place the shed of a wooden deck. I will then put metal (roof flashing) over the wood and screw the metal to the walls. Then install wood (plywood) over that. I will use two layers of plywood for strength.

Certainly, these steps would help, but it's hard to say how much. Perhaps you'd end up with 25-30 dB of shielding at the end of it -- just an educated guess though. One thing that can greatly compromise buildings like this is wires running in and out. If you are going to have power (or data) wires pass through the wall of the room, you'll need to take protective steps, like filters or ferrites.
I would highly recommend purchasing the amp bags and much less $ then shed project.
Excellent explanation. Thanks.
How do you solve the Decay (Dentrite effect) of Lithium battery batteries inside your power supply?
In 5 years time after the production , whether you use it or not.
The quality or the capacity of those lithium power supply will go downhill.
Is the only solution to buy new unit every 5 years?
So how do you do it while it’s plugged in? Shield the entire thing? How do you mitigate heat when enclosed?
❤❤❤
So how do you know when to put your items in these bags? If you’re using them, I’m assuming they can’t be in these bags.
Do lightening protectors on home and solar systems work against EMP as well?
I don't see why that would help. Lightning would have direct contact with the rods whereas an emp covers everything.

It was even referenced in the movie independence day. Anyway the military claimed they had to shut off in ten one billionth of a second and emp shield did it in 1 in a billionth over and over again. That's the claim at least. I'd say they probably do protect from emp but I wouldn't bet the farm on it.
@@richardk.3140😂😂😂 sure buddy LMAO even if I believed you you really think we should trust the federal government now??😅
Why would the government lie to us? They got us through covid
I have a question: will a solar panel ( from Harbor Freight) that is not hooked up to anything, still get fried in an EMP? Also, so you know of any singles sites for preppers? Hard to find a mate that is on the same path as a prepper/awake person.....just saying
"How to protect against EMP":
Buy my stuff.
Good answer.
Hey, if it works that’s genius advertising , American ingenuity on full power ⚡️
Thank you for sharing tour knowledge with us especially in these times facing us 🙌
Fantastic presentation! You made the complex very simple to understand, especially with all the baloney that is floating on the internet. Thanks again.
I agree. Great presentation by the very knowledgeable gentleman.
I have a metal tornado shelter above ground would that protect any electronics I have stored inside ?
It would offer some shielding, but it's not possible to say how much without taking some measurements. Best guess, maybe 10-15 dB of shielding. That certainly helps.
Bro your tools in your shop are so organized. Love it
my shop is such a MESS. I am like W C Fields and know where everything is ,, ,, until I don't, Then I go through an enormous cleanup-straighten up process. I am envious of seeing all the screw drivers in such strict order.

Protecting operational equipment from radiated EMP is very difficult.
If the whole house surge protector protects against the conductive threat, aren't all your large home appliances still susceptible to the ambient threat? So how could freezers be protected.
As a part two to my question, would a typical modern chest freezer, like you could buy at Home Depot with no digital display be susceptible to the ambient threat?
My question also.
Doc, how could I protect 100 watt solar panels from an EMP? Are there bags big enough to fit a 3'L panel? Or could you make shift a box covered in foil backed duct tape on the inside and out? Would something like this give me enough protection?
I used the boxes they came in, thick aluminum foil, and aluminum tape. Panels are not super sensitive.
You are selling anti-static bags as 'EMP bags'.... On your website..... so I think we know how you earn a crust!
People who tell me I need stuff and then offer to sell me some snake-oil are shameless. The inverter you put in that anti-static bag has a 2mm thick metal case.... and you say it needs the protection of 0.1mm of conductive plastic! Simply absurd. DO SOME RESEARCH PEOPLE - learn what a faraday cage is - check out the protection offered by sheet metal compared to mylar and unsubscribe from this charlatanism.
Static bags, and lay a cloth over bigger stuff including cars? As another engineer that’s studied EMP AND SGEMP, are you kidding me? 5000V/m radiated effect won’t be touched,and ferrites won’t do conducted more than what? 20 dB. This is a false sense of security.
I keep getting mixed info. Do solar panels need protection or not
Im not sure that you fully understand what an EMP is and how they actually cause damage. Electrostatic bags are fine for reducing radio frequency signals but have zero effect on magnetism. The damage to electronics caused by a an EMP is unique to the type of EMP and is manifested by a fast transitioning extreme intensity magnetic field that has the flux level to generate destructive currents in circuits and wiring (even circuit board tracks) that can damage semiconductors and associated software of many devices. The only true protection for high speed EMP's (Nuclear) is full MU metal shielding... not RF faraday cages and not anti static bags. They are snake oil fixes, an EMP is not RF energy, you need to block magnetism for effective screening.
Hello how long would you expect a military emp to last?
Seconds, minutes days, weeks?
Will a metal building, be a EMP Cage.
Spend money on a faraday duffel and keep your power station turned off. I feel like if you really fear for an emp, you just accept it and fork over the money.
Hi,
Wondering if you would be willing to repeat your EMP bag shielding effectiveness test at say 10-20 MHz an then share the results with us? The shielding effectiveness as a function of frequency is going to vary depending upon the thickness of the conducting material and the test frequency. There is a big difference in the skin depth thickness required to effectively attenuate a 10-20 MHz signal than it is a 500 MHz signal. It is going to require a much thicker conductor (or one that has some magnetic permeability) to effectively attenuate low frequency signals. E1 EMP signals start becoming much less significant after about 100 MHz. The bulk of the energy is contained between 100 KHz. and 100 MHz.
or do a real test of the radiation inside a 2mm thick faraday cage like that inverter has before and after you put it in one of those bags you sell - which will have no impact on the safety of the inverter.
55 gallon metal trash cans with lids !! it works !! line the inside with card board, you can store a lot of electronics.
thanks DOCTOR !!
instead of cardboard, i took a regular plastic/rubber trash can and cut off the top 4 inches, great insulation
Thank you for taking the time to explain things.
Best wishes!!!
How come the generator does not need the cloth to go underneath it, but the other items need a completely sealed metal bag to surround them?
Hi, Just a question, Is there a way to protect against an EMP attack or pulse if you have a Pacemaker ? Please !
Just use a bed sheet and drape it over the thing. Put some bricks or rocks to hold it down. Then mark the bedsheet on the outside of the bricks or rocks. Take it all apart and that will give you the size you need.
Multiple turns through the ferrite are much more useful. The impedance if the ferrite increases with the square of the number of turns through the core. So two turns is the equivalent of putting two ferrites on the wires. Four turns in the equivalent of 16 ferrites, etc.
True, except it won't increase the saturation level?
Isn't 2 turns equivalent to 4 ferrites?
And rhe saturation current rating will drop accordingly.
Correct on both accounts. (I see I made an error-- yes, you are right on that, 2 turns in equivalent to 4 ferrites) However, note that the saturation only applies to common mode current, not the the differential mode flowing in the cables. This should be relatively low, as it is what you are trying to get rid of anyway. @@HelloThere-nz9ld
How does a ferret protect against an EMP? I don't even think you can get them at pet stores since the early 90 's anyway. Still don't understand
@@pixelupdates7041If their fur is moist they absorb a lot more radiation than you might think.
Thank you. I have some solar cables and inverters to put into those bags.
They have jacked the price of the Siemens FS140 Whole House Surge Protection to $362, used to be about $190!🤬🤬🤬🤬 Greedy basta***!
Finally got one for $190!
For my whole house generator the cloth would not work because it needs to run once a week for test. I built a 2 inch square wooden frame that fits over the generator and covered with aluminum mesh...expensive. Then I covered with aluminum screen to be sure.
Next is a tarp to keep out rain but vents clear. Grounded to 6 foot iron bar. So far, no EMP but hopefully will stand up.
Have surge protector on inside panel with three ferrits on incoming cables. Hope this helps.
If the generator kicks on every so often, you wouldn't want to cover it with cloth. It sounds like you've worked up a solution.
If you want those bags to be easier to get into, roll them down and apply adhesive Velcro.
Yes, that's a nice way to do it if you're getting in and out of them. Some people use large chip clips to hold them shut.
Interesting. Almost completely useless, like most of the obsession with EMP I've come across in the past, but he actually has quite a few more clues about electromagnetics than most. Trained high power RF Transmitter Tech here. We also did lightning protection for buildings on mountaintops.
Been putting some thought into this for obvious reasons.
I honestly believe if everything falls apart anyone who depends on these kind of amenities won't make it. It's either survive without power or die
Better go get some lawn mower engines that don't need electronics to operate.
@Adam Craig they won't be worth a damn either after a short while. Honestly I think the only option is get your heart right with God. Accept his sacrifice and debt paid and go on home with him when that day comes.

Could I ask you if MYLAR BAG works for EMP?
What's your opinion on ebayers selling military grade conductive cloth thats 39 x 42 inches for about 12.00 dollars. Heard anything good or bad about their conductive cloth? Love your UA-cam vids. Thanks.
He stayed in video he has tested 28 different types of cloth and sells the best he could find
Would that heat reflector aluminum rolled insulation work as a faraday cage/ blanket.?
Great info, thanks. Would you recommend a cloth covering for solar panels as well? thank you
My understanding is that free-standing solar panels are not very susceptible, so covering may not be required. Once they're connected to cables, they become susceptible, however, and would require ferrites on the power wires. I talk about this in a video I did on protecting solar power generation systems.
yes, anything electric may be damaged by EMP, best to be safe then sorry from bad advise!
Can you just wrap it in aluminum foil double it your solar power generator
Is aluminum foil conductive
I have a question. I have a 40x9 steel shipping container with a wood floor. I have nothing touching the walls for 6 inches all the way around. Can I store stuff safely in it? Great content by the way.
I've wandered the same thing, I haven't researched that yet. Did you find an answer?
Always great videos! What type of thread would you recommend for sewing your EMP cloth? Also, does the Siemens FS140 go into the fuse box panel or just on the outside meter? PS. Would you recommend using desiccant pouches to absorb moisture for long term storage of electronics in your EMP Bags?
Any thread works fine. I've tried regular and conductive thread, both worked fine. As for the Siemens FS140, it can go outside the home, inside and mounted beside the panel, or inside the panel itself, depending on if you have room inside the panel. If it's outside in the elements, they sell a weatherproofing enclosure for it.
@@disasterprepper I wish the UK had such men..Thanks for all the information 🙏
@@disasterprepper Will EMP take out solar panels? I know they have blocking diode that will need to be replaced... But what about the solar cells made of silicon?
Hi Dr. Bradley, great video thank you so much. I have two questions. One: you state that Lithium batteries do not like to be fully charged. I have two Jackery solar battery generators with lithium batteries. I usually keep them fully charged for emergencies. Should I not be doing this?
Two: you mention batteries with cables that are connected could be damaged. Does this include automobile batteries that are still in cars if the car is turned off. I realize that most all cars now have a trickle draw because of clocks etc. would these batteries be affected? If so, would connecting a high saturation ferrite to each cable coming off the battery protect it ?
Thank you again for all the work you put into your videos. I am learning so much, almost feels like my college days, just wonderful.
In general lithium ion rechargeable batteries shouldn't be kept fully charged as it shortens their life. You can read more on the web at places like batteryuniversity.com/index.php/en/learn/article/how_to_prolong_lithium_based_batteries/subscribe_thx. As for batteries with cables, it is really the connection to the grid (or very long conductors) that cause enough energy to come in and damage batteries. Cars are very complex electronic assemblies, and the only way I've ever found to fully protect them is to cover them with something conductive when not in use. Some people do put ferrites or other protective devices on their car battery cables, but unless the ferrites were high saturation, they would just saturate quickly.
@@disasterprepper Thank you Dr. Bradley. I will check out the web page you suggest. I was thinking of the ferrite for the batteries not the whole car. I figure if I can save damage to the batteries I can use them with my little inverter for power.
@@hummingwind8869 Ah, sorry, I misunderstood your question. Ferrites placed on the battery terminals could indeed help the battery to survive - assuming the high frequency energy was enough to damage it.
@@disasterprepper thank you Dr. Bradley. Stay safe, stay frosty.
Hi there. Do we need to protect solar panels for a solar generator or just the generator?
Wonderful info! 2 questions: 1) I have a similar power generator that would use solar panels. What protection would I do for the connection from that setup? 2) Ben over at Suspicious Observers is stating we’ll lose our geomagnetic protection from the Sun soon. If and when we have a CME there won’t be just one emp, but constant emp threat from the sun for thousands of years. How do I protect my solar backup etc when it’s possibly going to be energized threats several timers per week? Especially when I can’t detect when it’s safe to run something? Thanks ahead of time!
Small power generators can either be put in EMP bags, a Faraday cage, or wrapped with conductive cloth. I would also recommend using one of the T.R.A.P. transient suppression devices (see disasterpreparer.com/product/generator-inverter-protection/). As for our planet losing its protections, I assume that's being said due to the recent movement of our magnetic poles. Personally, I think it's much too early to draw any conclusions on that right now.
You do nothing but kiss your ass goodbye.
Technically your microwave is small faraday cage fyi. Just don’t turn it on lol
it doesn't work, i tried it with my cellphone, called it and it rings.
I am building a house and have installed lightning rods. Do they help or inhibit EMP protection? Also, does underground wiring in non-conductive conduit still act as an antenna for an EMP?
Any wire is an antenna for lightning /EMP. The critical factor is how much energy can it collect. Just regular post and wire fences can pick up a surprising amount of energy, but burying stuff in the ground will protect it to some degree. Stuff that is disconnected is pretty safe without any wrappings or special treatment. That includes cars.
How will an emp affect solar panels?
I watched some of your earlier videos when you were making foil boxes in your kitchen I think. I just never did do anything, fooling around over 12 years and now here I am trying to get my husband to look at your videos too. Thanks so much for all your knowledge.
We purchased a GENERAC whole house generator and finally got it installed last December. The people set it up to test once a month, so I can’t really cover it up with anything. Also it clicks on in seconds when power goes off, so if I make a cover for it and I am away I ruin the system.
Q#1: Is there any method of building a screen wire cage over the GENERAC! I could disguise it some how and allow air flow?
Q#2: Which of your books would be the best to start out with as I try to build or learn to block the current? I purchased “The Survivalist” yesterday but it has not arrived yet.
I purchased 6, galvanized steel, trash, cans, a year ago and still have not done anything with them. My husband had not watched any of your videos and two days ago he told me he put his spare CB radios in one of the trash cans. So even he is taking notice. I had to tell him he just can’t stick stuff in the can! Lol
If you get the answers, please share them.
Hey if you want those cans to work you need to insulate the inside or cover what ever you put in with newspaper. If they directly touch Metal to metal the currant will run into the electronics.
@@fajile5109 yes, I understood this from watching videos but afraid my hubby didn’t. So, we have to get some foam and cardboard to line the inside of trash cans.
From my understanding anything that allows air flow will also allow the EMP waves to get in... My suggestion would be to cover your generator and turn the breaker to that generator off while it is covered... You should have a breaker for that generator before it goes into you whole house baker box...
Check out EMP Shield. Small devices, about the size of a plastic electrical house switch box, you can add to your house, cars, generator, solar system, etc. You can usually find a $50 code from many youtubers. I used Reality Survival. Mention them for $50 off each device!
My solar generator is being stored in a carpeted closet…does carpet have any conductive characteristics where I would need to completely wrap my generator, or would I be good w/ draping EMP cloth over it while it sits on carpet?
Do rice cookers, coffee makers, induction cooking stoves need to be protected from emp? Even if not plugged in or plugged in
Thanks for the guidance. Surviving with my survival tools is ideal. Worried about those without who take my tools. There is always a bigger stick than mine. No food, wildlife first to go, then zombie apocalypse. Best to just dig a hole, bury everything in steel garbage cans.
Ground yourself before pulling the scotch tape off. You can generate a very high static charge which can damage your equipment.
I watched your presentation about using a garbage can. Problem is I need 20 “ at bottem to store generator. Can’t find can larger than 17 1/2? Tell me, where did you find one big enough?
It appears that a clever electrical engineer (whose brother is a carpenter) may together be able to build an EMP-proof "box" around a large (24kwh in my case) Generac Standby generator. (I think that option is likely far too expensive even if I could find someone qualified to do it!). So, could you comment on the "EMP Shield" (brand name), which is available everywhere to install in cars, homes, etc. Do they work, and how well? They've doubled in price in the past couple of years and are too expensive an option if the answer is any version of "it depends." Thanks in advance from a new subscriber.
This type of protection is increasingly necessary. Excellent job explaining.
I bought a small Honda generator and it is still in the box. If I wrapped the box in two layers of heavy duty aluminum foil, sealing the seams with foil tape (as used on heat pipe insulation) would that get me close to the 50db rating I need?
Yes, that should get you 50+ dB.
EMP shield sells protection kits for vehicles and generators that are based on the models they sell the military. Another alternative. Here in Oklahoma we just had several days with sustained winds above 40 MPH. Laying a cloth over something outside isn’t a workable option. It would end up in the next state by days end.
Auntie Em, Auntie Em
GDT (gas discharge tube) and an MOV (metal oxide varistor). Use both in tandem and that should give enough protection. Connect one end on the positive and one end on the negative.
Excelente information ℹ️. I will implement what you advice. Any link to get more information and the components?
Where do you purchase emp Shields for automobiles?
I have a couple of questions, but I would 1st like to start by saying that I love all of your books and I have them all on audible. If you disconnect your battery from your automobile do you think that an EMP or a CME would still have an effect on it? My 2nd question is will you be making a 13th book and your survivalist series?
If the battery is disconnected, the battery itself would be unaffected by an EMP, however, the car's electronics could still be affected. The energy couples into the cable harnesses and generates potentially dangerous voltages and currents. As for the 13th book, I probably will write another in time. Right now, I'm finishing my new book, "The Watchman." It's very similar in style to the Survivalist books. You might give it a try. It's currently for pre-order at www.amazon.com/Watchman-Arthur-Bradley-ebook/dp/B08FRQ9H7T
Hi I hope someone responds! We live in Minnesota. I was going to get a 10-20 gallon garbage can to make a cage out of. But, after I got to thinking about it one night in bed, I thought we should get something bigger, as I think it would be beneficial to put our king size electric blanket in there with a portable generator and solar panels. Would a faraday cage protect an electric blanket? In theory I think it would. Thanks for all your help!
Yes, anything inside the cage would be protected.

I know a old Cold war veteran about 80 years old. He was a technician that fired the honest John missiles from Greece into Soviet Russia.

How about sealing our garages from the inside with three layers of aluminum foil? I bet that would protect everything in the garage once an emp is deployed. We'd just have to make sure the area around the door overlaps to maintain the seal after entering and exiting the garage.
Quick question. Is wrapping foil around the inverter or anything else the same as the EMP bag? Thnx.
Foil can give you a good degree of protection, it tears easily, however, and once it tears it will lose its protection. The bags tend to hold up much better.

Hi, you covered most things but I have one question.
I have a solar system (panels, EMP Shield, charge controller, etc) as back up. It is connected to my home through the breaker box with a 40 amp breaker that is switched off, unless it’s in use. If the solar is in use, I shut my main grid breaker off( which also has an EMP Shield on it).

Doc, great video and advice. Question: I have a 12k backup propane/gas powered generator that I store in the wooden shed. I will connect it to a 50amp box via a 50amp cable (10 circuits) that feeds into my regular panel that has a utility transfer switch.
>>That said, is the fabric cover over top of the generator (unconnected and stored) enough to protect the circuitry in the generator if draped over it and touching the wooden floor? Do I need to encircle the entire generator, as in, will the energy be able to penetrate from under the wooden floor and damage the generator circuits or will it dissipate as it is not touching earth? Do I need to keep the ground wire from the generator permanently attached to the rod that is outside?
Second, would I be able to still use the aux box, or, am I outta' luck with that? Thanks so very much. (I live outside DC, so this is a concern). GOD Bless
I have installed a number of EMP Sheilds devices on our power panels, 32KW backup systems and vehicles and farm equipment at our ranch. Have you tested the EMP Sheild products? Are we protected w/this product?

Paint to your liking. Maybe $15 bucks total.
Keep all of your wiring to a protected minimum.
And consider, you might be the only neighbor,

Would anything stored underground be safe from an EMP?
You can probably go to an army surplus store and get a metal box that has a real rubber gasket and locking clamps to seal the lid.
Maybe steel ammo cases would work.
How about a micro wave oven, working or not. It's a faraday shield.
Put your phone, charger, usb cables, laptops, tablet computers and backup hard drives. If we get hit we will be back in the 1850's.
EE here. So what is the mechanism that a lead acid battery would fail due to an EMP????? Electronics(semiconductors) are destroyed due to breakdown voltages, gate breakdown, and/or junction temperature, old tubes didn't have that issue. So lithium batteries with their internal BMS could fail. Also EMP stage 3 induced DC on the grid are not blocked by ferrite beads, deconnection from any long wire(ie the grid) is the only solution to that.

How about moisture...condensation that might collect inside the bag from long term storage? Could you ground the cloth by clipping an alligator clip to cloth and plug in into a ground outlet on a receptacle in your home?
Most bags are not airtight, so it's usually not an issue. You could put silica gel pouches in your bag if you're concerned about it.
or wrap the inverter in a palstic bag and then aluminium foil, emp bags a fairly expensive.
