well the USA builds KY satellite to be EMP hard. ( have guy I know that does that) Shield EMP is complex.
it's only going to wreck electronics, not like you see on TV movies burning up starter motors, crazy.
but face it not one person or country has built nor tested an EMP atomic bomb. it is only a theory, not built yet.
its fear over fear.
The bomb would need to be focused some how, to do that, how , nobody knows for sure beyond theories)
They dream up EMP energy densities, first, (rabbit out of hat dreams) and then design shields to do that. (based on say CPU transistor feature sizes.)
what smart (tin foil hat )preppers do is put the radio and the chain saw in a huge (old-skool) steel garbage can and , flag it "FARADAY SHIELD"
but gee go gas , no go.
I am still awaiting for the Garbage can results. (with baited breath)
too bad we don't have diesel chain saws.??
so for points ignition keep a spare condenser or it will short out at EMP but is flywheel protected some some what.
yes one of them weirdest posts ever. fun for sure.
the NASA , once had million reward to prove any EMP solution worked in their lab testers.
had vast friends working this to get that reward. (who won was never told)
the problem was using a scope, we could not prove the scope was not effected, at the moment of the EMP making all readings a huge lie.
I think NASA did it only by modeling methods. Like they do global (worming -sic)?
I used to work in the test industry, and this topic is way way too complex. for anyone I know.(&me)
The is like making a Umbrella hail proof, and be stylish? who will lbe the tester?, not me. but sure sst mess won.?
