This 'inventor' is infringing on Yull Brown's U.S. Patent (U.S. Patent 4081656, 1978) for Brown's Gas. Hope he has a good lawyer.
Brown's patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=15&f=G&l=50&co1=AND&d=pall&s1=4081656&OS=4081656&RS=4081656
