Comment on Datacenters in space are a terrible, horrible, no good idea.

Yeah so there is some confusion here. The are radiators on cars or in houses, but those are more accurately heat exchangers. Then there are things like heat lamps, which are really IR radiators that convert electricity to infrared light that feels hot.
Most of the heat you feel at a camp fire is radiant from the flame, unless you are down wind and feeling some convective heat, but most of that heat goes straight up with the smoke.
There’s a difference certainly but do you think the people who seem to be floating this idea know the difference?
Hard to say, but they’ve been using resistive cooling In space a long time.
Also a tech ingredients made a neat video about building one and radiating heat out into space from the ground. It was cool to see what happened when it was cloudy and stopped working.
Radiative cooling is all you got in space.

Radiators also dissipate heat through…wait for it…radiation.

Right… and a carpet is a pet you keep in your car, got it.

Do you know how BIG they would have to be to dissipate a data center worth of heat to keep it as cool as on earth?

Do you know how much heat they would need to retain?
BeardededSquidward@lemmy.blahaj.zone 2 days ago
To prevent any moisture that might be in the air inside the data center from condensing onto electronics. Admit it, it’s a stupid idea and stop defending it as a legitimate one.

Do you?

Oh, you got me, turned it around. Oh dear, whatever will I do? Oh right, remark how you don’t know and should stop supporting a stupid idea in the first place.
