alt Hacker NewsAsserting the contrary is not an argument.
Nothing prevents SpaceX or anyone else from buying up the right to put these things on cheap desert land. They don't even need to own the land, just the right to wheel these things out on a trailer or a helicopter and leave them there.
A desert is significantly less harsh than space. If your radiator is sized for space, it's overkill in an atmosphere.

>If your radiator is sized for space, it's overkill in an atmosphere.
no. Again totally wrong.
The 20-40C air surrounding the radiator radiates at the radiator too. This is why a human immediately gets stone cold in space while not in the atmosphere - our body radiates away about 900W and receives 800W+ back from the atmosphere - our internal heat 'generation has to cover only the difference - less than 100W usually.
You probably meant forced convection cooling. That requires additional machinery. And that additional machinery is a significant part why ground based datacenters such expensive to build and operate.
To the comment below:
>The planet underneath anything in low orbit also does this, making this argument irrelevant.
no. Again, totally wrong. You've just stated that a human in LEO wouldn't get immediately cold when exposed to space. Just think about it for a second. And after that plug the numbers in thermodynamic calculator. You'll see your error.
>Likewise, the fact that convection exists even without the adjective "forced".
no. Again, wrong. Non-forced convection is pretty small. Use the calculator. And you'll understand why datacenters use forced convection.
