Water-Powered Vehicles

Despite how silly it sounds, water-fueled vehicles do exist. The most famous is Stan Meyer's dune buggy, which achieved 100 miles per gallon and might have become more commonplace had Meyer not succumbed to a suspicious brain aneurysm at 57. Insiders have loudly claimed that Meyer was poisoned after he refused to sell his patents or end his research. Fearing a conspiracy, his partners have all but gone underground (or should we say underwater?) and taken his famed water-powered dune buggy with them. We just hope someone finally brings back the amphibious car. http://www.trutv.com/conspiracy/in-the-shadows/the-18-most-suppressed-inventions-ever/gallery.html?curPhoto=6

It seems as if a lot of truth and beneficial things have been systematically withheld from humanity -- while a lot of lies and detrimental things have been systematically perpetrated upon humanity -- which might support my 'Vengeful Deities Punishing Humanity Hypothesis' -- who knows??
