JOOC, do you know anything about a company called Flibe Energy ? I've been trying to gather info on them, and while they have a nice-looking Web site, it seems the actual physical research is going on at ORNL and PNNL. The company gives its home as nearby Huntsville, AL where the founder and President (formerly?) worked for two companies where my father worked. In fact, he's described on several Web sites as still being chief nuclear technologist at Teledyne Brown Engineering, a position I didn't even know existed (my dad worked in the Apollo program, I don't remember TBE having *any* interest in nuclear). I'm still trying to find where they have actual labs, as opposed to paper offices.
