Reno; I have to stuff several large humble pies into my mouth, along with my best hat, all at once!
In the c.100 years period 1937-2040, worldwide coal-burning powerstations will have released 800,000 tons of Uranium, of which 6000 tons is fissionable U235, and 2 million tons of Thorium into the environment.
Not only that, but the fissionable U235 dumped in the average ash, as a waste product, actually contains more energy than the original coal!
