Faraday "Cage": Protect your important electronics from EMPs or Solar Flares


A Faraday "Cage" is a container or room or covering used to protect your important electronics from an EMP (Electro-Magnetic Pulse) or Solar Flare or other Space Weather. All metal surfaces inside the "cage" must be covered or lined (or the contents covered) with a non-conductive material, like cardboard or plastic, so the contents, within the "cage", are not in direct contact with the outer metal shell of the "cage".

Closing electronics in a microwave oven or wrapping them in aluminum foil are other "Faraday Cage" alternatives.

To test your cage, turn on and tune a portable radio to your favorite station and place it inside your cage. Close the cage. If the radio goes silent (except for static), chances are your cage is working to keep out radio signals which is said to be an indicator that the enclosed electronics are protected against EMPs, Solar Flares and Space Weather. You can perform a simliar test with 2 active cell phones by placing one in the Faraday Cage and using the other to call the one inside the Faraday Cage. While they should communicate outside of the Faraday Cage, they should not while one of them is secured inside the Faraday Cage.

To try and put things into perspective regarding the affects of Space Weather, the Gamma-ray burst of March 5, 1979, had it originated from the Milky Way Galaxy (closer to the earth), would have vaporized the earth instantly.

It's believed that an EMP (Electro-Magnetic Pulse) or Solar Flare or other Space Weather could take down the electrical grid of the United State and that it would take 6 months to a year to restore the grid to some level of its previous self. With that potential loss of resources in mind, it would a good idea to have a personal plan in place prior to any disastrous event.
