many-many words, going sideways and around as you can't go against the basic thermodynamics facts directly. What is your point?

My point, i'll repeat, is that while 80C GPU will still radiate while surrounded by 40C air, it will be receiving back the radiation from the 40C air, whereis in space it will radiate the same while receiving practically nothing back from the environment. Both cases obviously is considered when in shadow.

To the comment below:

>False

you wasted my time as you don't seem to understand the basics of thermodynamics.

>and also irrelevant as if you let the space based ones go into shadow you wasted most of the point of going to space.

again, you wasted my time as you don't understand the datacenter construction discussed in the sibling comments.

from my point of view, ben_w definitely understand thermodynamics better than you. I'll point out that generally speaking radiative heat transfer from air is not particularly significant locally: it only tends to matter in the details when you're dealing with the whole atmosphere, which on average is a lot cooler. The transfer is also not blackbody radiation, so even then you can't really plug the air temperature into a radiative heat transfer calculation and expect a sensible result.

>I'll point out that generally speaking radiative heat transfer from air is not particularly significant locally:

so, you also think like ben_w that if we put something into a vacuum bottle here on surface on the Earth it will get cool down like in the vacuum of space.

I'm not really sure where you got that idea from, but I don't think it's worth continuing to try to discuss it.

i clearly cited your words, and like ben_w you're trying to snake away from your words once it is demonstrated what a nonsense you've said.

You quoted something and them lept to a conclusion which is sufficiently baffling I don't know how to untangle whatever misconceptions led to it.

I do not waste words, perhaps read them and you will find out.

False as demonstrated in the words you didn't see the point of, and also irrelevant as if you let the space based ones go into shadow you wasted most of the point of going to space.
