Let me add that on rare occasions I have talked to investors and captains of industry from outside the field. That is, people who did not come to me for information. Most of them believe the comic book versions of cold fusion described in Wikipedia, the Washington Post and Scientific American. These investors have never seen the scientific literature. They do not know it exists. They think the effect was never replicated and that no peer-reviewed paper on it was published. If I believed that, I wouldn't invest in it.
Potential billionaire investors might not be very interested in scientific literature until they had seen a convincing demonstration -- something to light lights or heating up the room. Something, apparently, nobody can provide. But if anyone could, LENR would not be a hard sell. Anyway Kimmel invested, Darden invested, Woodford invested, perhaps Page and Gates invested and we are no further along, apparently.
