We can start small by protecting personal electronics.
We all know the silliness of men wearing tinfoil hats,
but really! But tinfoil may serve a purpose afterall.
Wouldn't wrapping your emergency portable radio
in tinfoil serve as a crude Faraday Cage for that device?
It might even be better to wrap a wireless laptop in the same.
And work out how to link it up to one's satellite-dish since
geo comsats already have some emp protection.
