Episode Details

Realta Fusion just shattered fusion energy’s biggest hurdle: they powered a lightbulb directly from their fusion device, WHAM — the first private company to do so. This breakthrough proves fusion can generate more power than it consumes, but the real win? They’re harvesting electricity straight from the reaction, not just heat. That means 20-30% more efficiency and a path to profitable fusion plants. CEO Kieran Furlong says this circular energy approach could revolutionize commercial reactors. Helion is also betting on this tech, backed by Sam Altman. With $36M already raised, Realta’s milestone is a major leap toward fusion powering the grid.
