Tell your friend to do what I just did, go to US Patent Full-Text Database Boolean Search and easily look up his name. He used to say he had patents in the 90's and the journalists who investigated his claims said he had none. It appears he was famous . . . . for claiming he invented free energy and super high mileage car modifications - and then running his investors broke with out ever delivering. But encourage your friend to not just believe Josiah or Dennis or whatever his name really is these days, but look up independent sources of information. Bob Park had a whole chapter on him in the book Voodoo Science. Skeptical Inquier had a article on his free energy claims in 1997
