I just like how Jed upvoted the above comment - yet he will insist, that Rossi is fraudster and snake oil dealer...
I just like how you ignore what I say and distort everything.
As I have said about a hundred times, there is some evidence that some of Rossi's experiments work. It is not out of the question. Other people have reported success with similar materials and techniques. On the other hand, a one-off observations of gamma rays does not prove anything. Instruments sometimes malfunction. Perhaps extraterrestrial events can cause a burst (I wouldn't know).
Rossi is a fraud now. Perhaps he was not in the past. It is impossible to say. He has always been very dodgy at best, as McKubre, I and many others pointed out dozens of times over the years.
