The same guy who was the creator of the initial N plants also invented the Flouride Thorium reactors. The atomic regulatory agency handed him his hat when he pushed for his safe reactor designs. I like the no 'forever' waste part.

If we ever crack the fusion problem thorium sounds like a good alternative for the next 50-100 years. I am just a consumer and not a scientist.
