> Some parts of the moon are permanently shadowed and therefore extremely cold, as low as -173 °C. This means that no energy or water would need to be expended to cool the data center.

That doesn't sound right to me. If there's no air, then only black body radiation can be used to cool the data center. That means a massive radiator, a lot larger than a heat-to-air radiator+fan used on earth.

to put it into numbers - at 80C (353K) 1m2 radiates 880Watts

I think though that instead of the Moon we'll be putting data centers into orbit - for 1KWt GPU we'll need 5m2 solar panels and 1m2 radiator - all together under 10kg, ie. $1000 at Starship prices while the GPU itself is $20K+ .

The kicker here is that the Starship launch price is cheaper than installing solar on the ground ( $2K/KWt and higher)
