He’s not winning any fans, due to sloppy physics. I’ve seen temperature reports that show an energy return from 0% to 40,000% return - and this could be easily resolved without a great deal of effort.
When you heat water to vapor, you go through a huge non-linear phase-change; this is where their error is manifesting itself.
So, how about increasing the water flow, where it goes in at room temperature and comes out at LESS than 99C? The energy output is very linear in this region - and this will clear about 100% of the smoke out of the whole hoax issue.
Certainly, he knows this ... so why hasn’t he done this?
He is either a crook or waiting on patents.
"Certainly, he knows this ... so why hasn’t he done this?"
You are un-informed. He (and Dr. Levi) have done precisely that, and a summary of the results can be found at the LENR-CANR website (in the news section).
The knee-jerk naysayers are simply ignoring that data, and concentrating on the steam approach.
