No one is talking about building a single massive structure. SpaceX has said they’re targeting 100kW satellites. A lot of them. Which they’re already pretty good at.
Technically it’s pretty straightforward. The only real challenge is making it cheap enough.
- root-parent 4mo agoLots 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/2026/01/ISS.jpg https://i0.wp.com/www.nationalreview.com/wp-content/uploads/...

Just ignore the hard parts, call them implementation details, then declare victory...
