And there's 2 million more oil/coal on earth than uranium, quantity wise?
Don't get me wrong, being an informed human being, I'm obviously pro-nuclear but if humanity main energy source become uranium then we will note have enough by the end of the century, at least by the current estimate (more funding will enable to find more uranium but it is an unknown which imply an existential risk).
The solution would be thorium based nuclear reactors which would feed humanity for at least a millennium! But by design they must be less cost effective (how much?) and needs R&D funding today.
- acidburnNSA 6y agoBoth uranium breeders and thorium breeders offer truly inexhaustible energy for humanity. Especially uranium, which is available in seawater at astronomical scale, and which replenishes first through runoff and then through plate tectonics. We'll run out of nuclear fission fuel roughly when we run out of nuclear fusion fuel in the sun (i.e. when the sun burns out).
