A new piece in the puzzle of Rossi's E-Cat, which is said to be able to produce power with a cold fusion reaction: UK energy departement (DECC) has taken an interest in this tecnology, and might even plan "further action", under some conditions. In the exclusive open letter we publish here, Brian Josephson, physicist, who stands by Rossi since the beginning, invites him to reconsider the importance of a new, fast scientific test, after Rossi's negative reply to Francesco Celani's offer.
Brian Josephson adds that he doesn't necessarily looks up to Celani's offer (which, for secrecy reasons, doesn't match the refutability standards DECC have indicated), but highlights the matter of the benefit that could follow a scientific test.
