You can radiate the excess energy away on the non-sun facing part. In theory.
There are even commercially available prototypes of that vacuum cooling technology, if you want to perform your own experiments with that concept: https://www.amazon.com/Thermos-Stainless-Ounce-Drink-Bottle/...
What about on the Moon? My understanding is that heat is the killer. There you could sink pipes into the surface and use that as a heat sink. There are “peaks of eternal light” near the poles where you could get 24/7 solar power. Latency becomes high but you send large batches of work. Probably not at all economical compared to anywhere on Earth but the physics work better than orbit where you need giant heat sinks.
That said anything has to be better then almost literally nothing so I'm still holding out for datacenters on the moon.
I asked Google for more information about AI datacenter in space. This was the first sentence, 'AI data centers are being developed in space to handle the massive energy demands of AI, using solar power and the vacuum of space for cooling.' > After laughing at "the vacuum of space for cooling" I closed the page because there was nothing serious there. Basic high school physics student would be laughing at that senten…

We have tons of space on earth. Cooling in space would be so expensive.
Falcon heavy is only $1,500/kg to LEO. This rate is considerably undercut here on Earth by me, a weasley little nerd, who will move a kilogram in exchange for a pat on the head (if your praise is desirable) or up to tens of dollars (if it isn't).

“Terrible, horrible, no good” is the new “considered harmful.”
Apparently the book whose title the phrase comes from [1] was published in 1972, four years after Dijkstra published "Considered Harmful". [1] https://en.wikipedia.org/wiki/Alexander_and_the_Terrible,_Ho...

There is lots and lots and lots of space on Earth where hardly anyone is living. Cheap rural areas can support extremely large datacenters, limited only by availability of utilities and workers.
We also have to build a lot more solar and nuclear in addition of the datacenters themselves, which we need to do anyway but it would compound the land we use for energy production.
If anything, I'd expect large-scale Mars datacenters before large-scale space datacenters, if we can find viable resources there.

Why is it my job to train the machines?
