what do you mean they can’t get rid of heat? radiators exist

All that gets you 70kW of cooling. Radiating to vacuum isn't very efficient.

Dang, sucks we can never improve any technology. Let's just call it quits, guys.

Technology is wonderful.

Physics still gets a say.

Maybe one day we can, but it's definitely not in a category "there is no doubt".

Of course not, where's the fun in that category?

And that’s sufficient for roughly 100 unoptimized DC grade H200s.

Not efficient, and it doesn’t have to be, because the cooling system has 0 opex cost. And capex clearly can be made to wor

OK, so you've got a football-sized solar and radiator array to support 100 H200s.

Why are we not building it on land again in some abandoned mall's parking lot?

Cooling space station is very different from cooling off chips. One requires extensive piping, other - a simple radiator.

Both require the same thing - moving heat - and you’ll find plenty of piping in a datacenter for this reason.

Space radiators are not very efficient due to lack of airflow in space.

Efficiency in the cooling loop is of no consequence as it has 0 opex cost in space. Do the capex numbers make sense?
