Elon Musk just named it. Starmind. One million AI satellites, each a flying data center wider than a 747, cooled by panels that glow their heat into the void.

This is not Starlink. Starlink moves internet. Starmind moves thought. Each satellite, the AI1, carries 150 kilowatts of compute on a 70-meter span of solar cells, runs the model on board, and beams the answer down. No building, no grid, no water.

The reason is in SpaceX's own IPO filing. The AI market it values at 26.5 trillion dollars hits a wall of electricity and water that Earth cannot supply at a sane price. Orbit erases both. The sun never sets up there, and a 147-year-old law does the cooling: in a vacuum, heat escapes only as infrared, so a panel facing the 3-kelvin void radiates it straight out, no water touched. Run that panel hotter and it sheds heat 16 times faster for double the temperature. What Earth data centers burn rivers to do, a glowing wing does for nothing.

Musk flagged the problem himself, in the same filing. SpaceX cannot get enough chips to build this yet, and the fab meant to fix that, Terafab, ten times the size of Tesla's Austin gigafactory, may fail. The prototypes do not fly until 2027. Astronomers are already in revolt over a million new lights crossing the sky.

Days ago, Masayoshi Son, who owns the whole AI stack on the ground, called space data centers pointless. Musk just named his and put a million of them on the drawing board. One man is reading his balance sheet. The other is betting on the laws of physics.

The piece works out which one the void rewards.
