Realta Fusion claims first direct electricity harvesting from fusion plasma in private-sector demonstration
Summary
Realta Fusion, a Wisconsin-based startup, claims to be the first private company to publicly demonstrate direct electricity harvesting from fusion plasma. On June 19, their WHAM demonstration device powered a lightbulb using electricity harvested directly from the fusion reaction. The company plans to use direct electricity conversion to heat plasma in its reactor, estimating about 90% efficiency — far surpassing the ~33% efficiency of steam turbines in today's fission reactors. The prototype converter targets energy from deuterium-tritium fusion, where about 20% appears as alpha particles.
