• Pacific Fusion claims cheaper fusion reactor by cutting costly components. • Experiments at Sandia National Labs show elimination of expensive laser systems. • Uses pulser‑driven inertial confinement fusion, replacing lasers with high‑current electric pulses. • Electric pulses generate magnetic fields that compress fuel pellets in under 100 picoseconds. • Faster implosions produce higher temperatures, boosting fusion efficiency for commercial viability. • Company aims for first commercial plant in early to mid‑2030s, ahead of competitors.
Article Summaries:
- Pacific Fusion announced that recent experiments at Sandia National Laboratories could cut the cost of its pulser‑driven inertial confinement fusion (ICF) design. The company’s approach uses high‑current electric pulses to compress tiny fuel pellets, rather than the lasers employed at the National Ignition Facility. By redesigning the cylinder that surrounds the pellet and adjusting the current waveform, Pacific Fusion was able to reduce or eliminate the need for additional laser or magnetic pre‑heating, which typically adds 5‑10 % of the total energy and increases complexity. The results suggest a potential 30 % cost reduction, bringing the company closer to a commercially viable fusion plant in the 2030s.
