Lots of 100 kW satellites, does not remove the problem. For 100 MW you need about 1000 of them, each with power, batteries, radiators, pointing, shielding, communications, propulsion, spares, and replacement. GB200s are not space rated and depreciate in 3 years... And a 100 MW data center is a tiny thing, will hardly make a dent on the compute landscape.

Do you see the massive white panels of this massive structure called the ISS? : https://i0.wp.com/www.nationalreview.com/wp-content/uploads/...

Those are radiative panels who do at a max ...drum roll...120 kw

Saying "the only challenge is making it cheap" is like going back 10 years ago and talking to Tesla FSD defenders.... Just ignore the hard parts, call them implementation details, then declare victory...
