Oh, Rossi has already been amply proven to be a fraud, and spent years in prison for it after his last scheme, Petroldragon. I guess they didn't mention that in the press release.
He was however present for the loading of the initial "fuel" and the extraction of the ash at the end of the test (which was stupid, and suspicious - especially given the witnessed isotopic changes in the ash).
Or it was smart, as it was necessary in order to create the 'isotopic changes' in the ash via a substitution.
Is a computer language with goto's totally Wirth-less?
