GoKawiilPacific Fusion begins assembling billion-dollar pulsed-power fusion machine in New Mexico
Pacific Fusion has started building a fusion device near Los Lunas, New Mexico, using more than 150 truck-sized Marx generator modules that will discharge enormous electrical pulses to compress a small hydrogen fuel capsule. The company aims to reach 'net facility gain'—producing more energy than the machine consumes—by the end of this decade, while also positioning the facility to support research on the US nuclear weapons stockpile.
GoKawiil's interpretation of the reporting above, not reported fact.
Achieving net facility gain with pulsed power would mark a major milestone toward practical fusion energy, offering an alternative approach to laser- or magnetic-confinement systems already being pursued elsewhere. Its proximity to a major nuclear-weapons lab and potential defense applications also underscore how fusion research remains intertwined with national security interests, not just clean energy ambitions.
- Pacific Fusion is assembling a pulsed-power fusion machine using over 150 Marx generator modules.
- The company targets 'net facility gain' - producing more energy than consumed - by 2030.
- The facility could double as a research tool for maintaining the US nuclear weapons stockpile.
