The brief

Analyst view
  • Achieved 1.1 keV electron temperature on LM26 in October 2026 with UK Atomic Energy Authority.
  • Listed on NASDAQ in July 2026 under ticker GFUZ, raising capital for commercialization.
  • LM26 path toward Lawson criterion: the temperature, density, confinement time threshold for fusion.

Technical approach

As reported
Compression

Magnetic field containment during compression

A magnetic field confines plasma during mechanical compression, enabling fusion reactions at lower pressures than some other approaches.

Demonstration machine

LM26 experimental system

Lawson Machine 26 uses a liquid metal liner compressed by pistons to heat magnetically-confined plasma toward fusion.
