I don't see how that would lessen their concerns? Exactly because space is a vacuum, cooling is harder since you can't do convection.

The math still checks out though. Scott Manley did a video on it, and the top comment has some corrections: https://youtu.be/FlQYU3m1e80

Scott Manley is a much more respected source than I am

30% of terrestrial datacenter power use is cooling. Space cooling is easier!

[dgellow]

What makes cooling easier in space? Isn’t it harder due to the lack of atmosphere?

[dzhiurgis]

Just need radiators, no fans, no piping, no ac compressors, no moving parts.

[dgellow]

How? There is no heat dissipation without an atmosphere. I mean, you have dissipation via radiation but that’s very slow

[roer]

Not that slow if the temperature is high enough. Power radiated is proportional to T^4

[datadrivenangel]

I don't want to run my cpus at optimal radiator temperatures... 1000s of degrees is not ideal.

But, but—convection!
