How close are we to nuclear fusion as a regular power generator?
"Pacific Fusion took the wraps off its latest pulser module prototype on Tuesday, a piece of equipment that allows the company to move ahead with its demonstration fusion facility. Construction on the demo is expected to begin this summer. ..."
"... Today, we’re excited to announce the completion of our second set of technical milestones, keeping us on track to achieve net facility gain, the point at which a fusion machine produces more energy output than is initially stored in the machine, by 2030. ...
With this milestone, we have now demonstrated:
- Architecture: The module is the highest peak power impedance matched Marx generator ever developed with 90-bricks in 9-stages and ~2-nanosecond timing jitter, tested into a variety of loads.
- Power: ~440 GW of peak output power and ~1.1 MV peak voltage in 80 nanoseconds. This is the highest power, single-step pulser module ever demonstrated.
- Critical components: We’ve validated a low-cost trigger system capable of synchronizing all stages into a single, coherent pulse – a key requirement for scaling to full system performance. And we’ve established the platform as a testbed for critical components like vacuum insulators, helping reduce supply chain risk.
