Thorium is a mildly radioactive metal that nuclear engineer Kirk Sorensen argues could replace coal, oil, and conventional uranium reactors, and this remix stitches together six hours of his talks and others into one case for the technology. Sorensen appears at TEDxYYC, Protospace, and MRU explaining the liquid-fluoride thorium reactor, or LFTR, a design that dissolves fuel in molten salt instead of using solid rods, so it cannot melt down the way Fukushima did. Robert Hargraves and Alexander Cannara add the economics and safety arguments, while James Kennedy explains how thorium processing could free up heavy rare-earth elements now monopolized by China. The film also flags a stranger detail: the US holds roughly one ton of U-233, a nuclear material that took $4.5 billion to isolate and cannot be found in nature, which the government is now spending $500 million to destroy. A five-minute summary opens the film before it expands into the full argument.
