Because it "is" a separate issue. His credentials or lack of same have zero effect on the data that comes out of the tests/demos.
"As for your discrimination between scientific fraud and financial fraud, keep in mind that Rossi has taken money from investors and has already tried to franchise his product."
Really.....prove it. The ONLY deal that was signed and public was that with Defkalion, and that was on the sole condition that Rossi got paid by Defkalion ONLY if his product performed to specs. That fell through not because of anything "Rossi" did, but because Defkalion couldn't raise the money. And if you'll look into his current requirements, the only difference between what he wants now, and the Defkalion deal is that the franchise fee has to be put into an escrow account up front, NOT paid to Rossi. Rossi STILL doesn't get paid unless his technology performs as specified.
"His goal, IMHO, is to defraud a bunch of people with his E-Cat story."
The above franchising conditions are NOT set up to benefit a scam. And in fact, given those conditions, a scam cannot possibly work.
Sure, I can easily prove that Rossi has already taken money. There are many reports that Rossi has already sold licensing rights to Ampenergo for an undisclosed sum. Unless these reports are false, or Rossi sold said rights for a pittance, you can see that Rossi has already gained financially from this endeavor.
