Pacific Fusion is developing a pulsed magnetic inertial fusion system intended to achieve net facility gain, producing more fusion energy output than stored energy input. Its approach drives fast-rising electrical current pulses to magnetically compress deuterium-tritium fuel, building on inertial fusion and pulsed-power breakthroughs demonstrated at United States national laboratories.

The company's design emphasizes modularity and affordability, assembling its pulser from thousands of identical mass-manufacturable units alongside a compact fusion chamber. Pacific Fusion is engineering the components and systems required to turn pulsed magnetic fusion into a commercially viable source of on-demand clean power.
