AI needs so much power that old coal plants are sticking around

Nuclear plants only have about a 15 degree C temperature gradient in their cooling water in winter, the waste heat is not very useful. Swedish power companies have extensively researched using their nuke plants for district heating since they were planning the plants originally in the 60's, but it's never penciled out.

Meanwhile you can run a CPU up to 95 C.

Who is talking about waste heat? If you want to heat homes you could just use the thermal energy produced directly at a much higher efficiency. You don't need the detour of electricity generation at all.

See, my point isn't really that you should do that, but the fallacy in thinking there is a "free" energy hack for crypto, AI, ... . Wasting electrical energy is always bad.
