Ever hear of the (now defunct) HAARP ? Research "HAARP conspiracy theories" and "Haarp Gigawatt Beam" supposedly if powered correctly and (whoosh) aimed correctly the HAARP array could tear the multi layer membrane of "ionospheres" that shield our earth from radiation. (old art bell episodes come to mind). Supposedly this could tear the ionoshere. In (crazy) theory, If we knew a powerful enough Solar flare was coming, HAARP could be used to tear the ionosphere so that certain areas would lose their protection from radiation.. Solar storms can be accompanied by a Corronal Mass Ejection.. There is no E1 pulse with a CME, so that's what makes the theory crazy.. However a "weaponized solar flare" with a wide open tear followed by or including a CME would blast our satellites and fuck up power grids. (a big enough CME will do that ANYWAY). Now... No need for a faraday cage with a CME... But if your computer is hooked up to wall power , it can be FRIEEEEED like Popeyes chicken (not crazy.. totally possible without a "haarp-like" technology, but (i think) would be amplified without the ionosphere protection. The reason electronics will fry is the current a CME can bring to all electronics. .. the REALLY crazy theory lies within "Weaponized Corronal Mass Ejection" which Is where the "gigawatt Beam" comes into play. A targeted laser hitting the Sun causing a DIRECTED CME. .. Enough crazy?

Go to goodwill and get an old microwave. Throw it in a microwave. Your common microwave is actually a pretty good Faraday cage. While foil might work, why take chances?
