Since I was in high school I've heared this story too.
By the way, Deuterium is the main component/substance for the controversial "Cold Fusion" theory claimed by two scientists Pons and Flieschmann. However, they become silent which led to rummors of pay-off from major oil corporations.
(from Wikepedia)
Cold fusion (sometimes referred to as low energy nuclear reaction (LENR) studies or condensed matter nuclear science[1]) refers to nuclear fusion which occurs without the extremely high temperatures (millions of degrees Celsius) required for thermonuclear fusion – for example, muon-catalysed fusion.
Cold fusion made worldwide news headlines in March 1989, when Martin Fleischmann and Stanley Pons held a news conference in which they reported producing nuclear fusion in a tabletop experiment involving electrolysis of heavy water on a palladium (Pd) electrode.[2] They reported anomalous heat production ("excess heat") of a magnitude they asserted would defy explanation except in terms of nuclear processes.[3] They further reported measuring small amounts of nuclear reaction byproducts, including neutrons and tritium.[4] These reports raised hopes of a cheap and abundant source of energy.[5]
