It Runs on Water is a video with Stanley Meyer demonstrating the water fuel cell in a car. Meyer claimed that he could run a 1.6 liter Volkswagen dune buggy on water instead of gasoline. He replaced the spark plugs with "injectors" to spray a fine mist into the engine cylinders, which he claimed were electrified at a resonant frequency. The fuel cell would split water into hydrogen and oxygen gas, which would combust back into water vapor in a conventional hydrogen engine to produce net energy. Estimates made showed that only 22 US gallons (83 L) of water were required to travel from one US coast to the other. Meyer also demonstrated his vehicle for his city's local news station Action 6 News.
The vehicle failed to work during a required demonstration of the water-fueled car in a 1990 court case. An Ohio court found Stanley Meyer guilty of "gross and egregious fraud" in a case brought against him by disgruntled investors. The court decided that the centerpiece of the car, his water fuel cell, was a conventional electrolysis device, and he was ordered to repay the investors $25,000.
Stanley Meyer died after eating at a restaurant on the 21st March 1998. An autopsy report showed the cause of death to be poisoning, leading to widespread conspiracy theories[6] regarding the oil companies' and the US government's involvement in his death. The question still remains, however that somehow this vehicle ran on water. A satisfactory answer to this question has yet to have been resolved.
