I am agnostic about LENR. I doubt it but I don't have a way of knowing for sure. But there is essentially no chance of being wrong about Rossi. His entire history and all his experiments which have been reported are consistent with crookery and completely inconsistent with someone who has the greatest invention of the last hundred years! And before you say "replication," WHICH replication? None that I have seen described here and elsewhere has been credible.
As for the Navy Lab, they do research on all sorts of things. For example, the military wasted millions on Rossi's thermoelectric converter prototype which never existed or never worked and they spend many more millions on "remote viewing" which is one of the easiest to test and dumbest claims of paranormal activity ever proposed. Their participation means little.
Anyway, as I asked before, show me where a Navy Lab officially "agrees with Rossi" please. Cite and link please. I don't believe it happened.
