No one can tell Rossi how to do anything. I have met mercurial inventors like that.
Ross is not a scientist. He's a businessman thoroughly acquainted with the fact that people will do their best to steal his IP, and in the past people have stolen his IP. His actions match that of a con man but they also match that of a mercurial & paranoid inventor. Rossi initially didn't even want to do ANY demos unless it was to paying customers. But his friend Focardi was dying of cancer and wanted the recognition.
Here's what I don't understand. He was demonstrating a COP > 10 much of the time. How do you fake that much heat? Surely if it was really COP <1 then the damned thing would barely feel warm. Even the most pedestrian observer would notice such a severe lack of claimed heat.
How do you fake that much heat? Really?
You measure it with tools you supply and only you interpret the measured data.
