About four month ago we had saved enough to finally purchase a solar and wind generator 1800watt with deep cell batteries. 4 - 100 amp hours. I am former Intell Analyst with the USAFSS from 1964-74 then retrained and retired in 1983. I have also study the solar activity for years. After purchasing the off grid emergency generator with solar panels and wind turbine seperately, I started making the faraday cages to protect them and other electronics we wanted to save from an EMP or CME. I have had electical experiance so I built a cage of 2" x 2" wood framing, with wood flooring and shelving in them. Large enough for the entire generator, panels, the electonic part of the turbine, emergency radios, CB's. FM Tansievers, battery chargers 110volt and solar, all our rechargable batteries, chainsaw guts, and other items needed if a masjor EMP or CME occurs. Always making sure none touched the metal cage. Styrafoam , or carboard or non conductive material can be used on the inside, although it is not needed as long as nothing touches any part of the screening on the inside. I surrounded the 2 x 2 wood frame with normal metal screen used for screen doors, all metal no paint on it, then stapled it to the wood. Where I had a door I wrapped the 2 x 2 with screening and stapled it down. I personally put them above the ground on two desks. After insuring the screening was all encompassing, I ran a thick copper ground (AGW 3 or 4) outside to a 4 foot deep grounding rod. (our area has damp dirt year round at about two feet deep. If you are in a dryer area the grounding rod must be deep enough to be in damp soil. The ground for the generator while being charged once a month with regular electricity is conntected through the wire by a punched hole and on the inside a metal conductive tube that has a screw on each end to screw tight the copper gounding wire. That way if you know a EMP or CME is coming in you disconect the ground until the event is over. So all was well, then about three days ago I was watching: Apocalypse 101 on TV and they built the same exact faraday cage I did, and put a radio inside then closed the lid and the radio stopped receiving the wave. So it works as I thought it would. If you have an all metal car where it will be a conductive item, IT HAS BEEN SAID, NOT CONFIRMED that I know of, if you have a ground like the faraday cage I built, then make contact with the matel frame it also is a faraday cage. It is suggested that if you know an EMP or CME is coming in to take the battery out and put it in the other faraday cages. This one I do not know about for sure or not, but if the wave will run around the outside of the car to the ground wire, it might work. Thought you might like to know this really does work as far as the faraday cage I built for the generator and other items.
