OpenStar Demonstrates Levitated Magnet Fusion Milestone
On Feb. 18, 2026, New Zealand start-up OpenStar Technologies successfully floated a half-tonne superconducting magnet inside a 5‑meter vacuum chamber of plasma heated above one million degrees Celsius, demonstrating levitation central to its levitated dipole fusion design. The prototype Junior, costing under $10 million, is not yet net-energy producing but proves engineering viability and paves a roadmap toward larger Tahi, Maui and Tama Nui prototypes targeting commercial output.
Scoring Rationale
Credible, industry-relevant prototype demonstration with clear scaling roadmap; limited by early-stage results and unproven net-energy production timelines.
