Liquid Fluoride Thorium Reactors (LFTR) - Safe & Cheap

LFTR was also invented by Alvin M. Weinberg, who pioneered Light Water Reactor (most common nuclear reactor) and has much better safety profile than any other civilian nuclear power technology. The greatest advantage with Thorium is that it is abundant, has better chemical and physical properties and yields more usable power than Uranium.

Mr. Weinberg as head of Oak Ridge National Laboratory, USA, demonstrated in the 1970s that LFTR is a much better technology for power generation while LWR is complicated and unsafe.
