Magneto-Inertial, Pulsed & Alternative Cores
Pulsed compression schemes that explicitly avoid massive static superconducting magnets, prioritising upfront-capex reductions and modular replicability.

Magneto-Inertial / Magnetized Target Fusion (MTF)
Core tech focus
Pneumatic pistons + liquid-metal vortex
Key milestones
LM26 first plasma (2024). Nasdaq listing (GFUZ) targeted mid-2026. Grid plant late 2030s.
Radical mechanical simplicity: synchronised pneumatic pistons compress a liquid lead-lithium vortex around a magnetised plasma. The liquid metal serves as breeding blanket, heat exchanger, and invulnerable first-wall.
FRC, MTF, sheared-flow Z-pinch and levitated dipole topologies. Helion's magneto-inertial FRC bypasses the thermal steam cycle entirely — plasma magnetic energy directly induces electricity in surrounding coils on expansion. TAE's continuous beam-driven FRC targets p-¹¹B, demanding triple products on the order of 10²⁴–10²⁵ keV·s·m⁻³.
- Pulsed-rep-rate engineering: sustaining 1–10 Hz operation with millisecond-scale energy recovery.
- For aneutronic FRC (TAE), bremsstrahlung scales as Pbrems ∝ Tₑ^½, capping Pfus/Pbrems at ~0.2–0.3 without non-thermal ion distributions.
- For MTF (General Fusion), liquid-metal vortex stability under pneumatic shock and synchronisation of dozens of pistons.
- For sheared-flow Z-pinch (Zap), maintaining kink-stability at commercial pulse repetition rates.
- Elimination of large superconducting magnet assemblies removes the single largest capex line in tokamaks.
- Direct-conversion architectures bypass the 35–40% Rankine/Brayton thermodynamic ceiling, pushing net plant efficiency past 60–70%.
- Liquid-metal first-walls (General Fusion) eliminate first-wall replacement cycles entirely.
Helion holds the industry's singular commercial benchmark — a binding Microsoft 50 MW PPA for 2028. D-³He fuel and direct induction allow compact, high-rep-rate modules suited to hyperscaler data-centre siting. General Fusion offers radical mechanical simplicity by replacing lasers and brittle superconductors with pistons, solving the neutron-wall problem via a rotating liquid-lithium barrier. Zap has demonstrated 1.6 GPa plasma pressure, suggesting magnet-free architectures may be the lowest-capex route.

Who built General Fusion
Dr. Michel Laberge founded General Fusion in 2002 after stepping away from a highly successful corporate career in laser printing and optoelectronics. Armed with a profound understanding of experimental physics and plasma behavior from UBC, Laberge sought to bypass the staggering capital requirements of massive superconducting magnets or ultra-expensive laser arrays. His breakthrough was approaching fusion from a perspective of radical mechanical simplicity. He envisioned Magnetized Target Fusion (MTF) powered by precisely synchronized acoustic shockwaves generated by pneumatic pistons, compressing a liquid lithium vortex around a plasma target—a distinctly pragmatic engineering philosophy that continues to guide the company's path.
