Ready to talk about Thorium again? Since the last Thorium Geek Out in 2013, there have been a number of important developments. Richard takes Carl on a tour of why we want Thorium as a fuel, molten salt as a reactor design, and the choices we can make around different turbine technologies.

Is it time to get building a molten salt reactor?
