New Zealand Startup Achieves World-First Levitated Magnet Plasma Confinement
OpenStar's $10 million prototype levitated a 0.5-tonne magnet and confined plasma above 1,000,000°C, advancing fusion tech with potential for compact, cost-effective reactors.
Today, Regional Development Minister Shane Jones announced a $35 million loan from the Regional Infrastructure Fund to support OpenStar Technologies after its Junior prototype reached First Plasma within two years.
Using an inside-out levitated dipole, OpenStar Technologies places a magnet inside the plasma rather than external coils, aiming to upscale its design for commercial fusion in New Zealand.
A 0.5-tonne superconducting magnet recently levitated inside a roughly 5-metre vacuum chamber using the Junior $10,000,000 prototype to confine plasma heated above 1,000,000°C.
The New Zealand government says the support will attract international investment and create high-skilled jobs while anchoring a bespoke fusion R&D facility, officials say.
With over $7.1 billion in industry funding and more than 50 companies, experts caution the road remains long as OpenStar acknowledges it will need $500 million to $1 billion to resolve risks.
