Helion Energy’s Trenta prototype surpasses 100 million °C, advancing pulsed D‑³He fusion that directly converts power

Helion Energy’s sixth prototype, Trenta, exceeded 100 million °C after 16 months of reliability and durability testing, and the company says this validates moving forward with its compact, pulsed, ignition‑free D-³He fusion generator that directly converts fusion energy to electricity. Helion frames remaining obstacles as engineering rather than scientific, claiming its small, continuous-running devices sidestep major grid upgrade needs.
