Yeah, when you heat something, it emits infrared. Kind of the nature of hot things.
I think CorrectAlias meant that heat transfer by direct contact, which is how we cool things in general, is not available, making cooling a datacenter cluster in space actual science fiction.
This is exactly what I meant, thanks.
@phutatorius @technology So, a high-efficiency thermoelectric generator, powered by #datacenter heat directly, might be a win-win. I don’t understand why the current (jk) #technology efficiency is still so low. Surely someone must be working on this.

you still need thermal radiators to create the temperature differential.
