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

Turns out you can’t cool something just by putting it in space because most heat transfers require convection, which requires a medium, say, air… which is notable lacking in space.

Yeah, heat dissipation is surprisingly difficult in space, because the only real way to do it is via radiation. And radiation is one of the least effective methods of dissipating heat.
The vast majority of heat transfer on earth happens via physical contact, in the form of fluids or solids touching each other. That’s what a heat sink is for. It increases surface area, so more fluid (air) can touch it and carry heat away. But without some sort of fluid contact, a heat sink isn’t going to help much. It’ll act as a radiator, but the cooling efficiency will only be a fraction of what is achieved via traditional forced air cooling.
