German Startup Proxima Fusion Bets on Stellarator Design to Achieve Commercial Nuclear Fusion
Proxima Fusion, a Munich-based nuclear fusion startup, is developing a stellarator called Alpha based on Germany's Max Planck Institute's W7-X design. The company has secured €400m from Bavaria and is seeking over $1bn in federal funding. Unlike tokamaks, stellarators use twisted magnetic coils to control plasma more easily but are harder to build. Proxima faces competition from 53 other fusion projects worldwide, including the UK's Step spherical tokamak project in Yorkshire.
