Okay, first thing to realize. All large power is steam power. It’s just a matter of different ways to heat the water and propel the turbine inside the generator. Space is really bad at dispersing heat. To the point where the problem with space stations and ships hasn’t been how to keep them warm, it’s how to keep them cool. We also already know we can pump heat around with water. So I’m wondering if it’s possible to off world the hottest parts of human development and then use the heat generated as a recycled energy source for the space stations we would house that infrastructure in.
