Unlike uranium-fueled reactors, LFTR's use commonly-found thorium-232 dissolved in molten fluoride salts as the nuclear fuel (since the fuel is in liquid form there's no such thing as a meltdown), and the reactor doesn't need to be pressurized, either. As such, LFTR technology--once perfected--could result in so much electricity generated we could phase out coal-fired power plants, electrify all railroad lines and do salt water desalinization on a gigantic scale, which could open up a lot of land for agriculture to solve the world's food production problems.
