The brief

Analyst view
  • 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

As reported
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.
