Formal collaboration partner with OpenStar

For the first time, a commercial company has confined plasma in a levitated dipole reactor — using a single half-tonne superconducting magnet floating freely in a vacuum chamber, held aloft only by magnetic force. Superheated gas swirls around it at over one million degrees Celsius. On February 17, 2026, Wellington-based OpenStar Technologies publicly demonstrated this feat in its five-meter-wide "Junior" prototype, with New Zealand Prime Minister Christopher Luxon triggering the final stage of the experiment.
