Fusion Startup Bypasses Thermal Limits With Direct Energy Conversion

Realta Fusion converted fusion-produced charged particles directly into electricity on its WHAM device, sidestepping the efficiency losses of conventional boil-water-and-turbine cycles. By circumventing Carnot limits inherent to thermal methods, the approach gains theoretical edge. Realta partnered with Commonwealth Fusion Systems, operator of the world's strongest superconducting magnets. The demonstration remains subscale; reproducible scaling to grid-competitive output remains the core engineering hurdle.
