Still easier to cool in the desert than in space
- andsoitis 6mo ago> Still easier to cool in the desert than in space What is the physics and the math than let you conclude that?
- thrance 6mo agoLack of medium in space so can't rely on convection or conduction there? This is really basic.
- andsoitis 6mo agoBut what if you need compute for activities in space? Is the desert on earth still a good option?
- dmos62 6mo agoPresumably that vacuum is an insulator.

- zajio1am 6mo agoYou can do radiative cooling in space (you just need big radiators). You cannot do that reasonably in desert.
- m4rtink 6mo agoTaking aside you certainly can do radiative cooling in desert at night just fine - you have air, which even if hot to desert standards during the day is still by magnitudes more effective for cooling via direct heat transfer than radiating heat away in vacuum.
- cyanydeez 6mo agoI did realize geothermal would be the way to do it in the desert; the ground is still typically cooler than the heat computers give off. It's still problematic that most deserts dont haveaccess to groundwater, so bootstraping and maintenance are an issue.
- konschubert 6mo agoYou can try to put the heat underground. Maybe there is an aquifer you can use. Or maybe your desert is close to the coast! Still easier than radiating it into space.
