❯ Musk says SpaceX is casting its own blades, pulling gas turbines forward by 18 months

casting in-houseMusk confirmed SpaceX is building its own foundry to cast gas turbine blades and vanes, saying it can bring gas power online up to 18 months faster. The Information broke it from job listings that explicitly name a “blades and vanes foundry.” The site is in Bastrop, Texas, near SpaceX’s existing Starlink factory, where the company bought roughly 830 acres between March and June.

why do it yourselfThe bottleneck is supply: only three foundries worldwide make these parts, and their order books run through 2029. The process is genuinely hard — each blade has to be grown slowly in a vacuum furnace as a single unbroken crystal, without the microscopic seams that let cast metal crack under stress. That is difficult even for the smaller blades in jet engines, and power-plant turbine blades are considerably larger, which raises the difficulty of defect-free volume production. The same capacity can also serve Starship engine production.

where the power comes fromThis is the second item this week pointing at the same thing: what limits AI expansion now is electricity, not chips. Emerald AI frees room on the existing grid with scheduling software; SpaceX is going straight to manufacturing generation equipment parts. Compute companies building their own data centers need to redo their timelines — when a competitor can pull power generation forward by a year and a half, the bottleneck on the build schedule moves. The cost is equally clear: gas generation brings its emissions problem along.
