At the dawn of the atomic age, uranium and thorium were equally important as the elements of choice in researching nuclear energy - either one could have powered the world's reactors. But it was uranium that won out, and thorium, which is far cleaner, safer, and more abundant than uranium, was relegated to the dustbin of science. With it went the possibility of creating a low-risk nuclear energy source to power our planet. Now, as the world searches for cheap, non-carbon-emitting energy sources, thorium is reemerging as an overlooked solution. As one of the first energy experts to promote the development of thorium, award-winning science writer Richard Martin combines science, new historical research, and a timely business narrative to show how we can wean ourselves off our fossil-fuel addiction and shift to a lower-risk energy source. At once a big think book and a science manifesto, SuperFuel challenges us to look back at what could have been different in history as well as forward to an energy revolution in the making.
