Scale up nuclear power
How to scale up nuclear power enough to decarbonize energy?
Things that won't work
- Conventional nuclear power - Uranium-235 is too scarce.
- Small nuclear reactors - Same scarcity, plus greater risk of weapons proliferation.
- Uranium-238 breeder reactors - Abundant fuel, but still a weapons proliferation risk.
- Hydrogen fusion - Will probably be viable in the distant future, but we can't wait around.
Projects needed
- Thorium breeder reactors - Safe reactors that run on very abundant fuel
