i remember another guy who claimed to have invented an electrolysis technique that was very efficient, and even built a car to showcase his "water engine." he also claimed to have received a billion dollar offer from the saudis to "sit on" the technology and cease development. he was poisoned a few years ago if memory serves.
interesting stuff, the world of autos is rapidly changing.
