Infinite Energy, 'The Magazine of New Energy Science and Technology,' has devoted its entire current issue to analyzing the work of Joseph Papp, the Hungarian inventor who claimed to have built some kind of fusion-powered engine that used noble gases as fuel (i.e. we're talking 'free-energy' technology here). In the 1960s he also claimed to have built a submarine that could travel at 300 mph, and in a test run of this craft he said that he travelled from Canada to France in 13 hours (the airplane ticket that was later found in his pocket debunked this claim). Infinite Energy has one sample article about Papp on its website. I've also got some pictures of Papp's submarine on my site.
