The liquid fuel thorium reactor: safer, cleaner and more efficient than nuclear.

It is interesting to note why Thorium is not being used as widely as it should have been. Most of the nations chose to invest in development of Uranium since it can help them build nuclear weapons whereas Thorium does not.

On the other hand, India, which has scarce Uranium but a lot of Thorium, has been leading the research and development of Thorium-based reactors using fast breeder technology. China too has focused its research based on molten salt as the coolant as are other countries including US, France, Japan and Russia.
