He needs to cut the crap with the whole “secret sauce” spiel and just lay it on the line.
He would get the Nobel prize, his name would be in every history book printed from now till doomsday next to Edison and Bell, he would soon be one of, if not the, richest men on the planet.
But the longer this drones on with the teasers, the more ridicule he will stir up. And IMHO, he will deserve it!
He probably would if he could get the patent, but the USPTO rejects cold fusion patents.
His box outputs 10,000 more energy density than gasoline. That part is independently verified. It is no longer a stretch to accept that he sent similar boxes to customers, which he claims he did. So the ball might have started rolling.
