The brief
- Prototype Junior levitated its half-tonne magnet while confining plasma above 1 million °C in February 2026.
- Up to NZ$35 million government loan (Feb 2026) for a facility to house its next device, Tahi.
- Raised about NZ$20 million privately by 2024; plans a neutron-source business before fusion power.
Technical approach
Levitated dipole
One magnet inside the plasma
A single superconducting ring floats inside the chamber; plasma is trapped in its field, like charged particles around Jupiter.
Active levitation
Held up by control, not supports
External electromagnets under real-time control keep the ring in place without touching it.
