I wonder how well it would work in something as strong as an EMP? My new garage and basement is under ground on three sides. Maybe this on ceiling and garage doors/wall would be a great solution?
That blanket will work really well in a solar EMP. The reason it will work so well in an EMP is that a solar event isn't going to affect anything other than the long wires and large transformers and generators connected to those long wires. It might even work to prevent damage from smaller static electric shocks because they are carried on the outside of a conductor. Will it protect against a direct lightning strike? No because it has no high current path so the charge is diverted through the blanket faster than around it.
An HEMP E3 pulse closely resembles the solar EMP but covers a smaller area. The HEMP E2 pulse is similar to a lightning flash but it covers a much larger area. The HEMP E1 burst is an extremely dense airborne positive charge that exists from an altitude of about 10 miles above the ground to about 30 (or more) feet into the ground. This airborne charge is made up of air molecules that have been stripped of their electrons. It is not a radio pulse that can be grounded. It is an electrified atmosphere so if you want to protect some electronic gear from the E1 pulse it has to be in an air-tight container that quickly carries the charge around your gear and does not become a capacitor plate in the process. If you insulate your gear and then place a metal shield around it you just made a capacitor, with your gear the negative plate. It will fry.
To protect your gear from an E1 burst you need to build it into a nest of capacitors that will slow the penetration down as the pulse dissipates in the air. Three layers of capacitance is the minimum shielding for protection. That means that you need to cover your gear in a good insulator, then a layer of aluminum, silver or gold, with at least two more layers of insulation and conductor in air tight covers. Using zip-lok bags and heavy duty aluminum foil you can build a good shield against the E1 burst. The insulation should be as close to 50000 volts of dielectric strength as you can get and the conductor has to be aluminum, silver or gold, with no holes. You are not trying to protect your gear from a radio signal but rather a rapid burst of positive ions that fill the atmosphere with 50000 volts per meter. That voltage can't hurt you or penetrate your body but it will penetrate metal in a capacitive reaction. You have to delay that power for a period long enough for it to dissipate before it gets to your gear.
