Joe Hansen(@joehansen):SpaceX already makes turbine blades. For Merlin. High heat, high RPM, cracks that NASA would not accept on a crew flight. They spent years on that and changed the part. The next job is bigger blades for gas turbines that feed data centers. Those parts sit in a few foundries with years of backlog. Elon wants the casting inside SpaceX to cut that wait by as much as 18 months. Rocket blades exist. Power-plant blades do not, not yet.
