Technology Assessment & Commercial Milestones

Princeton spin-out replacing the famously twisted stellarator coils with an array of simple planar HTS magnets whose currents are tuned dynamically to sculpt the optimised 3D field. Thesis: Manufacturable, repairable planar coils unlock the stellarator's steady-state advantage without bespoke 3D winding. Key engineering bottlenecks: Real-time field error correction across thousands of coils; HTS magnet array thermal management. Recent milestones: 2024 — $20M Series A led by Prelude Ventures.
