Geothermal power from craters?

on a sidenote, it would also force moon/asteroid-bases to be more lategame since you have to built fusionreactors on them since they will not generate heat/wind and have less exposure to the sun due to blockage from the planet.
Multiple types of PGens add all kinds of awesome!

We won;t have just "fusion generators!" because fusion is an immensely difficult high-tech process. At least, in anything under the size of a star.

It's why we've been pouring money and technology into it for the past 50 years and even now, 2050 for an operational plant is optimistic.

Solar power is cheap. Dirt cheap. I mean, for us right now it's not, but if you can just nanolathe square miles of silicium then yea. Especially if you place them in space, where they have over 2x more solar exposure and 24/7 steady power.

Wind is not as cheap, as is tidal. However, they have a much greater energy density, and thus are useful.

Geothermal largely depends on the source, since 40 degrees celcius water also counts as geothermal energy. Lava straight from the core would be an excellent, relatively low tech solution for tons of power.

What i would like to see however, are Fission reactors. These would only be buildable on rare source spots and bring a lot of power into play.

Then as a top-tier, Fusion.
