Ive been thinking about nuclear war quite a bit lately, I dont feel anxious but I do like to feel prepared. While I think the main priority should be food and water for the ensuing famine, having a laptop might be beneficial (obviously no internet though).
Ive heard about bombs knocking out telecommunication, but do they also fuck up the personal electronics permamently of people who are far enough away not to be killed by the blasts?
I fail to understand why it needs to be grounded. I tried to search a bit but no one seems to have a physical account for their claims.
Basically, the energy needs to go somewhere. A feraday cage isn’t meant to absorb EM energy, but to redirect it safely away from sensitive electronics. Otherwise, itcoulds still transfer that energy into your electronics.
For example, EMI shields inside your electronics, which are technically feraday cages, are grounded.
