@zleap er, no? they're a weird form of nuclear power that the navy put up the money to develop. apparently sodium is much better at whisking heat than water is and possibly you can also merge the nuclear fuel with it so you end up with a much safer reactor that doesn't create the same amount of waste.
the concept has been proven but nobody will allow or fund nuclear reactors that can't make bombs
@zleap @icedquinn Wikipedia has a good article on this: https://en.m.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor
Also interesting is the article on the one they built and ran back in the 1960s:
