what are y'all saving from the wild to deal with coming crisis?

So I should keep my laptop in the microwave? Understand it would possibly disable automobiles since they have computers in them. Need to get a bigger microwave for that! LOL!

by an old microwave and keep all your electronics in it....

A Faraday cage is easy to build but the materials are a bit pricy..... a simple one would be a car sized metal box with no openings except the door. The door has to have EMI seals which are made of rubber and copper wire.

I have been around very large Faraday cages.... Large enough to wheel a work wagon into. and have seats for three or four workers to do testing.

They are eerie.... Calm inside.... even in a frenetic loud workshop.

Does the earth's magnetic field shield us from the sun's electromagnetic pulses?
I did a quick search and can't find the answer.

Yes for the most part.... You can see it in action in the Aurora Borealis.

i seem to remember a conversation about a cage in a B-52 cockpit

probably measuring EM fields... Static electricity plays havoc on test equipment....

Each arc can be as much as 40,000 volts.... miliamps of course but enough to wipe out EPROMs.....

But yeah Airplanes in the air are not grounded.... The friction between the air and the skin can cause a static charge.... The lightening strike goes up for the most part....

From solar wind, which is plasma and other particles. Solar wind shields the earth from cosmic rays. Solar wind correlates with sunspots. When there are little to no sunspots, like we are experiencing now (solar minimum), then there is less solar wind and more cosmic rays hitting earth's atmosphere. Some scientists (Svensmark et al) are working on proving a hypothesis that increased cosmic rays causes increased cloud cover, which causes cooling.

I will have to think about this topic for a while , maybe years

So would it be better to retrofit my garage, or take over the chicken run?

The concept is pretty simple. Cosmic rays cause small atmospheric particles to clump together (nucleation), which provides a surface for water vapor to condense upon and form clouds, which block the sun's radiation, cooling the earth.

Dad was an Aviation designer...amongst many other things... If he needed something he would build it... Hed be 89 ish now. and yep he was a Redneck Farmer Boy built his first plane when he was sixteen from a basket of crashed parts.

He refined a lazer system to go in the nosecone of a fighter jet... made the Physists design idea work.

for what its worth I used to design EMF antennas for microwave transmission... The engineer would specifiy how it should look and I would try to draw it up.... I swear to got it was voodoo.... I still couldnt design one on my own. The engineer used to chuckle at me and agreeed....
