I am no engineer but this Thorium Reactor seems to be a step in the right direction. Any of you retired scientist might comment on why something like this has not taken off. Here is a link to the TED (Technology, Education and Design) Talks page. These are lectures done by new and usually innovative people who get invited to these lecture forums to share information. Thanks for your interest. We could use this type of inexpensive power to replace or supplement nuclear.
