EMF/EMP fabric or paint

[steptoe]

ok just wondering on emf fabric or paint how good it is and if it is worth stocking it , i have made a few faraday boxes now and looking at the bigger picture making covers for my generators and also for the power stations i am now getting ,i am wondering do i have the internal roof space painted with a coat to help deflect the waves from above and also keep enough extra fabric that can be joined with tape or try and get one big piece to line say a whole room in the event or do i get enough to recover say a 3mt x 3mt gazeboo that could be put up in the living room should it even come to it .

Ok well hoping you guys may know some on this stuff i do as i say have a few boxes already made that work and looking at storing other items that would need protection , and would it be worth buying a big enough piece to cover the car engine with like a 2mt square that could be put in the engine bay and tucked down round the engine ,i know might sound like over kill but keeping a working car would be a huge bonus , i wish i had kept my dads old Granada now a 1980 2.8 with 30k on but hey ho

ok look forward to replies i am sure Andy must have some knowledge on this ,or hey Andy how could i ste in place a way to turn a very large shed/shipping container into a faraday cage , i know in the movies they do some weird stuff but i just wonder how easy it would be to do ie grounding it and so on

Honestly, I think you are overthinking this aspect.
You realise that a microwave oven or a biscuit tin would be a faraday box/cage ? If your mobile phone can't get a signal inside it, it might be working.
And as to protecting your car, you'd probably just need to wrap the computers ( immobiliser and seat belt computer might be separate ) Oh. and how would you wrap the wiring loom? No point wrapping the whole engine.
Did you ever watch experiments where they subjected cars to artificial lightning?

If a car can take that EMP, then what's the problem?

My understanding is that EMP's would aspire to induce damaging current in major power and communication cables and antennas, to blow the equipment on the ends of it. The vulnerability exists because the hundreds of miles of overhead cables that act as a receiving antenna. It might damage our TV's through induction into the ariel, or whack our routers and computers via pulses on the mains and phone line. But the odd pacemaker, car or led lamp would be unlikely collateral damage. I'd only fear the effect of EMP on that infrastructure. I don't worry for a second about the risk to small battery devices or cars.

A few EMP bombs have actually been detonated as a test...

Hi jenny you may well be right i do tend to go over board as the wife says overkill my end , i am the same with my shooting i say why have a less power rifle that may still kill a deer or go boot and braces and have something i know can stop an elephant .

Well i guess i will keep thinking on it but i will look at ways to protect my pacer because if that goes i go , i take the point on the car i was looking at just protecting the engine and computer parts in the engine bay that run the engine same as generators that have onboard sine wave convertors do we not need to protect them if we should want to use them .

well i am new to all the electric and stuff like that so i guess more reading is needed .

thanks again for the input

With the car, I speculate that the EMP would be 'picked up' by the car wiring, if anything. That's everywhere. Don't see how you could shield that (any better than the car body already does)
Your pacemaker.... Hmmmm. possibly at less risk of EMP as the whole of your body being vaporised by a regular nuke, or being smashed to bits under your blown up city.
There's a lady on this site swears blind her pacemaker is disrupted by windmills, and another guy saying his was affected by a TV store. It's a natural fear of the unknown. But don't we have enough known things to fear, like blasts and fallout, nerve gas and poisoned water, riots and starvation, etc. etc.
Maybe This will reassure you. https://mdcreekmore.com/will-pacemakers-survive-an-emp/

As I understand it, All mains inverters use a bundle of electronics to make the AC output. Probably some tiny, low power integrated circuits which then drive chunky power transistors, which in turn drive transformers. The only difference between modified sine and pure sine ones is the complexity of the circuitry. If either are fragile enough to be blitzed by EMP, then probably both as bad. Again, as I understand it, any EMP pulse would get to it through what are effectively it's 'ariels': The lengths of cable connected to it and any transformers in it. The EMP device explodes hundreds of miles up. I personally would no more fear that than the Northern lights or a sunny day. The effect on the power grid, or communications, I acknowledge.

Hi jenny yes i know they say about things interfering with the pacer , i can say first hand it is true . i had a pacer no more than a week and wife took me to asda the paceing clinic said i was just unlucky , the day i went some person must have been testing the security bar things you past to go in store lol i sent the alarm off on the way in got puled to the side guys frisked me the work and then asked me to lift my shirt as he said i was wearing clothes with a tag in he checked but as i went to lift me left arm my wife screamed no as i still had the stitches in we then said about my pacer and funny he even wanted to see the op site lol .

I rang the clinic who asked me to go in and they checked it was running ok lol i also had it when we pasted a a scrap site that had a huge electroc magnet going and we got stuck in traffic the other side of the fence the pacer went made i mean heart rate hit the roof the traffic moved and with in a minute or 2 it settled spoke to the clinic who said it was more than likely that , i also got stuck right next to a mobile radio mast that set it off you do get use to it , mine is a bugger as i have a dual chamber if the one goes off nothing much never felt it but sometimes when the double goes you get a kick in the hcest for less that 20beats to 140 beats in seconds lol yup you get a rush .

My old one lasted 19 years meant ot last 10 - 12 lol i got a good one but toward the end of life it did get set off and sent in to emergency mode that is not nice i can tell you that , a heart rate of 140 a minute when you are trying to rest is not nice

Thanks again jenny likei say i do go over baodr the wife has to rein me in sometimes liek the shooting lol oh t is a good job we have been married 36 years and due to my accident i forget stuff so wife has credit cards and wallet we went in a gun shop omg well let's say i would have been broke lol

Hi jenny yes i know they say about things interfering with the pacer , i can say first hand it is true .

You surprise me. But you should know.

I sent the alarm off on the way in got puled to the side guys frisked me the work and then asked me to lift my shirt as he said i was wearing clothes with a tag in he checked but as i went to lift me left arm my wife screamed no as i still had the stitches in we then said about my pacer and funny he even wanted to see the op site lol .

Alarm or no alarm, I'd have raised merry freaking hell at the idea of a pat down or intrusive search. Indeed, I'd have complained at the alarm noise stressing me. They would have not seen me exit the store without an abject apology and a free weeks worth of groceries. Being asked to lift your shirt is grossly inappropriate. If they took you to a private back room that could have been an illegal detention. If they did it in public, it could have been assault.
My blood boils at the thought of such impropriety.

I used to work inside a faraday cage for my job. It was just a shipping container with cabling to earth the outside. I don't think conductive paint is going to do an awful lot for you. If there is a solar flare or an EMP big enough to knock out cars etc it will probably swamp the paint. You need a very low resistance to earth across the whole area surrounding your items being protected and i dont think the paint will give you that.
Yes there is a risk. Yes a pacemaker is probably a worry but you can;'t spend you whole life inside a Faraday cage. I could keep a phone and a radio inside a metal biscuit tin just in case - but there might not be anything left for them to talk to if it is that bad. I may do better to concentrate on low tech or tech-free solutions instead which will last forever.

Yes jenny i was amazed not joke the guy had me stand legs apart the lot and parted me down there and then people walking past and lets say i was well known in the area not for bad reasons lol , then he had me lift my shirt i wear jogger and very loose top and was at the time due to the op and the stitches still being in this was back 20 years so the stitches were to be cut out ones , the guy even when we told him made me pull my top so he could check , i was well i think gob smacked and hence we turned round and left, in this day and age i guess i should have sued but if i am honet i am not a sue type person if you get me i use to always deal with my own problems in life .

I will say we never shopped at asda again , but even the pacer clinic said wow we have hear now and then people had issues my pacer was a new type just out that month but it did it no harm and they not4ed it down but said it may well have been the testing of the system that did it as it may have been rolling through frequency and just been unluck to hit mine .

In this age of Facebook and Twitter, I suspect they let more real crime go. I know one store where they take no action at all even where someone walks in, bold as brass, lifts a load of stuff and walks calmly out.

I'm still enraged thinking about that behaviour. he'd have got no further than a hand on my shoulder before I'd have screamed for help and lashed out, (defensively.) He'd have woken up just in time to get handed his notice.

I know jemmy my wife was joking with some of the people we knew that were on the way out saying that it was an interview to become a stripndale , but don't laugh one of the girls said to me wife well i have seen him naked and i ain't paying lol , that is why i say i was well known lol .

Back on to the emp fabric i have lined a few wooden boxs on the outside then lined the box with neoprene foam and these are to store a laptop and other cards that i will save the ebooks to from that site hehe , i keep all my memory cards in a safe box just incase .

Thanks for all the advice
