Other companies have launched data centers,
a single h100 for a preliminar test is not "launching data centers".
and radiators and heatsinks are different things. heatsinks make no sense here unless you want to periodically shoot them of to outer space and replace them with new ones. unless you have a groundbreaking new solution, space is the heatsink here, and you need radiators. where are they?
all i can see there is 4km2 of "panels". they look all the same, maybe half of them are meant to be radiators? their "paper" (*1) states that at 20 degree celsius a dual-sided 1m2 black plate would dissipate 838 wats, which is true. then you would need over 5km2 of that for a 5gw datacenter, not to mention you also have to transfer that heat from the cpu racks to the plates over kms of distance. if you keep the plates at 80 deg celsius the area shrinks to about 3km2. btw the llm that did that math for me also mentions that at current manufacturing and launch costs getting all that material up there would cost $60 billion. the mentioned "paper" says "$5m (single launch of compute module, solar & radiators) which definitely sounds like pipe-dream grade stuff.
again, i'm not saying it is impossible, just that i can't see how it would make sense, and i've yet to see a solid proposal, it's all hype and handwaving. so you can't build those datacenters on earth for some reason, and you're going to build them in space? really? sounds like just another way of siphoning more investor money.
