Nobody has the honesty to say that it is impossible to stabilize a magnetic field at a temperature over 100 millions K, and everybody is happy like an Easter.
And the experts used to say that trains couldn't go through tunnels at more than 25 mph because the pressure would crush people, and they used to say that electricity would never be practical, and that solar energy and windmill electrical generation would never work, and Edison considered his patents on the "moving picture machine" pretty much worthless because who would sit for more than a few minutes to watch, etc. The list of people, experts or otherwise, who have been wrong at one time about just about everything, is endless. For example, there are many experts who say that LENR or cold fusion is impossible and a pipe dream. I don't know, but I encourage the exploration of it, as I believe most of the people on this forum do. But do I believe in Rossi and that he is anything other than a charlatan, con man, crook and fraud? No. I don't believe in him, I don't believe him and I have yet to see any rational evidence based argument for doing so. To me, people who believe him or believe in him, are taking everything about him on faith. And to me, that is a religious belief. And to me, a religious belief that is belied by all the evidence and facts.
