Repetitive pulsed-power drivers
Key milestones
Sandia Z-machine architecture adaptation.
Adapts Sandia's Z-machine pulsed-power architecture for repetitive, mass-produced commercial operation — the most direct attempt to commoditise national-lab pulsed-power IP.
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 Fuse Energy Technologies
Founded by JC Btaiche, Fuse Energy Technologies is built on an aggressive hardware-iteration philosophy that bridges national security infrastructure with deep-tech energy development. Btaiche structured the company around a modular pulsed-power approach, intentionally building machines that serve dual-use markets. By engineering compact fusion devices that generate intense radiation fields, Fuse addresses immediate defense testing requirements and aerospace simulation demands today, utilizing current market revenues to systematically derisk the path toward grid-scale commercial power.
