Liquid-fluoride-thorium reactors are very different from the kinds of nuclear reactors you have heard of. Anyone who wants to say something for or against nuclear energy should watch at least the first few minutes of this video first. My title is a quotation from Kirk Sorenson in the first few minutes of the video. Kirk is amazing at explaining nuclear reactor technology. Kirk also has a much shorter TED talk as well, here. 

Casey Thormahlen suggested this video, and this book by Robert Hargraves: Thorium: Energy Cheaper than Coal. Here are Casey’s tweets.
