Molten Salt Reactors Providing Power in the USA in 20 Years?

Nuclear Engineer, Lou Qualls, Ph.D. spoke this week at the Oak Ridge Institute for Continued Learning about the future of the molten salt reactor technology that was developed by the late Alvin Weinberg, Ph.D. back in the 1960 at Oak Ridge National Laboratory.  Will this timeline be too late?  In my opinion, there has been little continued learning about this technology.  Weinberg devoted the latter part of his life promoting and lobbying the government to develop this energy source, but was told to 'go away.'  For the last few years we have been giving the technology away for free to other countries.
