Silicon is the other half of the stack
TeraFab is not a side factory. It is the compute loop that has to close with Starship, ice, and power — radiation-hard chips in orbit, edge silicon for the machines that build the city, wafers that match the catcher tower.
The loop
Published loads
- Chip split
- 80% D3 / 20% AI5
- D3 duty
- Radiation-hard orbital servers
- AI5/AI6 duty
- 50× edge efficiency for Optimus
- 100 GW / yr
- 1,000,000 t hardware to orbit
- Wafer starts
- 1M / month at Grimes County
- Rule
- Land the booster or there is no server
The files
Papers on this desk
Two notes hold the TeraFab argument. The backbone is why a terawatt fab exists. The unified machine is why the tower, the wafer, and the robot are one loop.

Breaking Ground on Terafab
Grimes County. Logic, memory, and packaging under one roof. More than a terawatt of demand against a planet that cannot print it. A groundbreaking is not a wafer.

A Hundred Gigawatts a Year
A million tons a year at 100 kW per ton is 100 GW of new orbital compute. A path to 1 TW a year from Earth. The math is not a constellation.

One Unified Physical Machine
If you cannot land the booster, you cannot launch the server. If you cannot package the chip, you cannot power the robot.

TeraFab Is the Silicon Backbone
Stainless steel makes return impossible until you close the ISRU and compute loop. A terawatt fab is not a chip factory. It is the bridge off Earth’s gravity well.
The same numbers sit in the dossier, next to ice and watts.
