Technology Assessment & Commercial Milestones

Princeton Plasma Physics Laboratory (PPPL) spinoff founded by Princeton astrophysicist Amitava Bhattacharjee and former PPPL Chief Science Officer Michael Zarnstorff. Stellarex uses advanced AI and HPC to design optimized stellarator configurations that relax the punishing manufacturing tolerances historically required, aiming to commercialize the inherently stable stellarator geometry. Thesis: optimization plus modern manufacturing can collapse stellarator cost — buy the steady-state physics without the artisanal coil bill. Key bottlenecks: precision coil manufacturing at reactor scale, and divertor and tritium handling in a 3D geometry.
