I'm very curious (from an academic thought-experiment standpoint) what sorts of mitigations could be used for electrical lines in an environment like this. My first thought - an alternate reality where you could turn power to (say) 100kW of light and then back again - would actually not be enough, as light can be pulsed so rapidly we're already using it to encode data. Welp. I'm guessing that UPS-type equipment was used as a form of powerline isolation, at least.
