I’m still not sure how people can believe this, this makes zero sense to me.

There is no easy passive cooling in space, getting rid of heat is a major problem. And you need more redundancy because the radiation will crash your computers. And launch is very expensive of course.

And the whole presentation is completely ludicrous. Look at table 1 in the linked PDF and tell me you’re serious. There is no additional cost when sending a datacenter to space except launch cost and shielding? Building a server farm on earth is the same price as building a satellite you can launch on a rocket as long as you use the same computers?

Read the "Thermal Management" section, page 8 ...

I believe that it’s physically possible to build something like this, but there’s no way it will be cheaper or simpler than cooling on earth. In their comparison table (table 1), they have earth based cooling for a 40 MW cluster over ten years at 7 million dollars and on the right side calculate the space cost as $0 (although they only imply that it would be cheaper than on earth by saying it’s „more efficient“). If you believe that their cooling system will be less than 7 million with enough redundancy for 10 years (or alternatively maintenance or replacement missions), I don’t know what to tell you. It’s not happening.

It sounds easier to transfer the heat to comets or building the datacenter on the moon.
