The Video is entitled, “Cold Fusion: Physcists Sven Kullander and Hanno Essén interviewed about the Rossi-Focardi cell”I find it interesting that in the video, it's clear that their support of Rossi is based entirely on believing everything that Rossi says. For example, they mention that he has "heated his factory for a year using the E-Cat". Unfortunately, there is no actual evidence that he has done anything like this.
Scientists work on the assumption that their peers are honest. This is necessary to avoid having to start each experiment from first principles. However, it leaves very little protection against fraud.
The solution to detecting fraud is to have others repeat experiments and verify similar results. However, Rossi refuses to allow this to happen. Therefore, Rossi is "cheating" the scientific process.
He is welcome to do so, but as long as he does, any claims he makes should be disregarded.
I recall the brilliant scientists of MIT when Stanley Pons and Martin Fleischmann were hard at work. Openly, they derided him in the extreme. Behind the scenes, they filed a slug of patents on ways to possibly use the technology. We have a world of blithering hypocrites. Something like powered flight comes along and the rage to stop it and deny it because God didn’t give man wings becomes fervent.
