In this episode of Earthlings 2.0, we chat with Kieran Furlong, CEO and co-founder of Realta Fusion, about the promise and progress of nuclear fusion as a sustainable energy solution. The discussion touches on the mounting pressure of rising global energy demand and why nuclear, specifically fusion, could be a game-changing response. Kieran explains the fundamental differences between nuclear fission and fusion, the risks and legacy of fission reactors, and the promise of fusion technologies that don’t carry the same waste or meltdown threats. He also explains Realta’s modular, cylindrical “magnetic mirror” design that offers a simpler, more scalable path to fusion energy.
