Could a Faraday box or cage foil an EMP weapon's destruction?
There is something that you can do to provide EMP shielding for sensitive electronics and that is to place such items within a Faraday cage or box. This is simply a metal box such as a filing cabinet, metal ammo box or other metal box, that is lined with some kind of insulating material such as cardboard, Styrofoam or material. As long as the equipment inside does not touch the metal walls of the Faraday box or cage, the EMP will travel harmlessly around the outside of the box without harming anything inside.
While some suggest that an old microwave oven might be perfect, others suggest that a simple metal trash or garbage can with a tight-fitting metal lid would work even better. It is even possible that a cardboard shoebox, wrapped in aluminum foil, provided that the foil doesnt get torn, would provide a cheap Faraday box.
Since it is not practical to place your vehicle in a Faraday cage, is it true that an EMP pulse could result in an entire countrys citizens finding themselves walking? Not necessarily, but for more information on cars and EMP go to EMP Shielding.
