markie - where are you getting all this additional information from, it doesn't seem to be on their website?
It's common knowledge to those who have been following BLP's progress over the last three years, when a breakthrough was achieved. I think it was February 2014 when Mills did an audienced presentation showing the explosion of hydrated metal and the unprecedented high power yield. At the time he thought that it was a typical explosion. If I recall correctly, he was considering using a magnetohydrodynamic drive to harness the energy. It was only a little later, after more closely analyzing the reaction kinetics, that he discovered that by far most of the energy released was photonic and not kinetic. It was then that the idea of using PVs was conceived.
