Elon Musk says SpaceX is using its rocket-engine casting shop to make turbine blades and vanes, the parts that run 12 to 18 months behind the rest of the turbine, so it can bring power online 12 to 18 months faster than anyone else “So we’re casting the blades and vanes for the turbines. So SpaceX already has a very advanced castings capability that was developed for rocket engines." "So we have, I think, actually the most advanced casting capability on Earth, because the demands for castings for rocket engines exceed the demands for anything else you could possibly imagine." "So, taking that incredible team that has, I think, objectively the most advanced casting technology in the world and saying, hey, can you guys also make some blades and vanes for terrestrial turbines is much easier than what they have done in the past." "And when we talk to the turbine suppliers, they tell us that the blades and vanes are 12 to 18 months behind the rest of the turbine. Meaning they can deliver everything except the blades and vanes 12 to 18 months before they can deliver the blades and vanes." "So casting is this really difficult bottleneck. And if anything, it seems to be getting worse." "So that means that we can bring power online 12 to 18 months faster than anyone else." "That’s the kind of advantage that’s difficult to replicate. Unless someone else is building an advanced casting shop, they will be unable to compete with SpaceX in this regard.”
