Here is the opinion of a couple scientists who are in the camp of using thorium as an energy source:

After studying the feasibility of using thorium, nuclear scientists Ralph W. Moir and Edward Teller suggested that thorium nuclear research should be restarted after a three-decade shutdown and that a small prototype plant should be built.[4][5][6] Research and development of thorium-based nuclear reactors, primarily the liquid fluoride thorium reactor, (LFTR), MSR design, has been or is now being done in India, China, Norway, U.S., Israel and Russia.

What do you think?  Is this viable or dangerous?  Feel free to comment.
