Technology Assessment & Commercial Milestones

National Institute for Fusion Science spin-out building on the LHD heliotron lineage — a continuously operating helical stellarator with liquid-metal blanket. Thesis: LHD has already operated for thousands of hours; commercialise the world's most operationally proven stellarator class. Key engineering bottlenecks: Liquid-metal blanket scaling; Heliotron compactness vs. classical tokamaks.
