Axil - you know the answer to that. A couple of parlor tricks worked then certain academics issued a report that corroborated the R'ster spin.
He fooled many folks when he first got started. When real engineers got involved, he couldn't handle it but still tried to pull off his next money grab, failed then had the unmitigated audacity to litigate as part of his ongoing scam. That was his undoing. That is where the truth caught up with him - $$ story ends there.
While we're at it - you're a good person to ask since you know so much - do you think that the R'ster is still "engineering" all of these amazing new contraptions in Florida?
IMHO, Rossi's partner came up with the idea for the SK reactor and may have built it. It does not make sense for Rossi to make the QX reactor redundant. My sense is that the new partner is taking over a major part of the engineering that is going on in Rossi's shop. Rossi seems to be working at the partner's facility where SK development is occurring.
