You'd use frequencies that can penetrate cloud cover in that case, it wouldn't work otherwise because then it would still be subject to weather.
Some sort of orbital death beam? I seem to recall a 2000ad story around a space energy beaming facility that goes horribly wrong.
Oh sure, it sounds extremely dangerous, just like standing too close to a radar will poach your brain. The satellite beaming the energy back would have to stay on target and if it didn't it would need a quick and safe way to shut off. Of course dissipation of excess energy in a ground-based grid is a serious issue, so how you would design a satellite to deal with the sudden stop in energy flow is completely beyond me. Maybe you just write it off and launch another one in that case, and you have a lot of redundant paths rather than one critical one.
I don't know for sure but it's particulates that make it a nuclear winter, not just cloud (water) but would also need to penetrate the clouds as well.
It's probably not wise for me to Google "what frequencies of EM can penetrate a nuclear winter clouds" though ๐
That's actually a pretty good point and I don't know how it would work either. It would definitely interfere with the signal to some extent.
