perhaps somone who was there can enlighten
I viewed Miles' talk more of a historical background talk instead of a "how to make heat" talk. He spent some time talking about China Lake and the "politics" of the situation. It was about work done some time ago.
I do know that several are now working on getting material made (Pd B) and that they want to get it into hands of people to try using it. Also McKubre should be giving a talk at the up coming Italy meeting on the role of B.
