How would one go about doing this, don't ask I'm curious and well you never know when one country is gonna stir up shit and cause M.A.D. in all countries.
Faraday cage, surge protectors? Of course a lightning strike will blast through surge protectors, so it's best to unplug devices in a storm. I unplug my computer during a severe storm.
Thick lead box will protect just about anything, right?

[editline]09:05PM[/editline] Also: Like mercury, another heavy metal, lead is a potent neurotoxin that accumulates in soft tissues and bone over time. Lead poisoning was documented in ancient Rome, ancient Greece, and ancient China.
You will want a backup generator as well, and lots of solar panels, batteries, and an inverter in an apocalyptic situation. Gas will run out, and then you can't fuel your generator. That's where the solar panels come in.

If there's some sort of EMP wave, it's going to knock out more than you're computer. The internet in the area will be knocked out, the phone service and most importantly: Electricity. You'd have wayyyy more to worry about than playing video games if there was some sort of EMP wave.

Electricity can always be created.
you'll have to shield every transistor in your PC and mouse and keyboard and monitor.
oh god if we had a solar flare ALL UNPROTECTED HARD DRIVES IN THE WORLD WOULD BE WIPED! I bet someone would make a makeshift bunker? :v:
[QUOTE=don818;20907513] Electricity can always be created.[/QUOTE] Heum yeah not really if an Emp blow Nuclear central/dams will stop/or being destroyed
[QUOTE=genyus;20911690]Heum yeah not really if an Emp blow Nuclear central/dams will stop/or being destroyed[/QUOTE] Generators that run off gas will work. Also homemade dynamos and quite a lot of other things could be used.
[QUOTE=don818;20906357]How would one go about doing this, don't ask I'm curious and well you never know when one country is gonna stir up shit and cause M.A.D. in all countries.[/QUOTE] I actually asked my physics professor at university about this. You can not shield anything from magnetic fields. The best that anyone has done is created a material that hyper concentrates the magnetic field somewhere else in the device so that they don't go through the important parts. You would either push the magnetic field above the whole device, below, or both.
EMPs are Electro-Magnetic though, You can block them (light? radio waves? microwaves? etc.)
Since an EMP induces a very high voltage in conductors if you had a shit load of steel surrounding your shit the magnetic field may favor the steel rather then the small electro conductors in your pc. But really you can't stop a EMP magnetic fields go through everything.

If you're that concerned, gloves? :downs: [editline]03:11PM[/editline] Not that a lead box would work that well anyway.
Maybe FP members should start building bunkers around the world. Still a lot of ideas for shielding.
I asked my AP Physics teacher today. She said she couldn't think of any ways to "disperse" electromagnetic waves... which means it's probably not possible 'cause she's a genius.

Lead blocks electromagnetic waves, radioactive waves and pretty much any other wave you wanna think about.
Usually, if somethings unplugged and away from antennas in a EMP blast it's unaffected
Bros, albeit also a wave of the electro-magnetic variety, magnetism is not the same as light. You cannot block magnetic waves (that is, untill we find some exotic matter that behaves so, but science isn't that far yet). You can however have a material which is even more conducive of magnetic waves and thus draws them away from the object of choice <--Somebody has already mentioned this and they are absolutely correct. A Faraday cage would work using basically the same principle (this brings me to mention: let it be clear we are taking deep liberties in simplifying everything for the sake of understanding). This "shielding" is highly dependant of it's placement. Also, some good news: a fine wire mesh grounded to the Earth would work better than a lead box; that should save you some money lol... unless of course you have already bought the lead coffin. In which case, I present you a sad faic :(
The matter would have to have intelligence and polarize the opposite of the field in every instance of its composition faster than the speed of light.
you'll need to run copper wire at a low voltage around an object to shield it, if you want to make a room EMP proof then get some copper threads, they are about a .23 inch thick and shield everything
Maybe try red tape? It helped in the movie pulse. (I think thats wat its called.)
Those harddisk bags (anti-static bags) might come in handy. They can suppress your mobile phone signal, maybe completely with a few layers.
[QUOTE=binarybitz;20933364]Those harddisk bags (anti-static bags) might come in handy.

Also the idea of copper wire, sounds good but has it been tested? Also wouldn't I need to layer it almost like a sheet of copper?
I'm surprised no one has mentioned Faraday cages yet. There the best protection we've got (AFAIK) against EMPs.
