#353 – Dennis Whyte: Nuclear Fusion and the Future of Energy
Lex Fridman Podcast
The Difference Between Fusion and Fission
Fission works by the fact that when that fission occurs, it actually produces free neutrons. Free neutrons can trigger other fission reactions if there's other uranium nearby or fissile materials. The first sustained chain reaction was done underneath a squash court with big blocks of graphite. So at its heart, what you do is you very quickly put together enough of these materials that can undergo fission with room temperature neutrons. And so this process can essentially grow mathematically like very fast and so this releases large amounts of energy. That's how our fission power plan works. We're just using fusion reactions as an intermediate catalyst to basically to get even more energy out of it
