100kW? Nvidia BGX 200 servers are 14kW each, not counting the interconnect, or anything else. According to nuggets I’ve read online, we’re talking 200 megawatts for an Earth-based AI datacenter these days, without something exotic like underclocked Cerebras WSEs
Plugging 200 megawatts into this:

I get about 0.46 square kilometers, depending on the coolant temperature and ultimate efficiency of the system.
I have no clue what the construction of such a monstrosity would look like, but if it was a simple 0.5 inch aluminum sheet, it would weigh like 15,000 metric tons.

They aren’t making a datacenter like on earth. They’re putting up a ton of satellites that will each generate about 100kW. Everyone keeps thinking they’re putting these massive things up there, they are not doing that.
