In my fiction I have a city deep underground on the planet of Venus. I know this is deeply impractical, and there are far easier places to build an underground city, but that is not what I have done.
The question is this, could I protect the city inside a shell of suitable material that uses the Peltier effect to cool down the internal space from the extreme temperatures outside of the shell. And if so, presumably I would need to generate an enormous amount of energy to power the Peltier effect, so, any ideas on the best method of generating such energy deep underground on Venus.
Any other ideas for alternative heat exchangers that would work on such a large scale, and under such extreme temperatures would be appreciated.
