http://ThoriumRemix.com/ He was a chemical engineer by training and he knew that in chemical processes the reactant streams are almost always liquids and gases- they're fluids.

And in fluids a completion of the various chemical reactions are possible.

He looked at the nuclear problem and wondered if the same principle might not apply.

And they began investigating some very radical nuclear reactors, totally different from the stuff we have now.
