1993: Stanley Meyer on One World Government and Alternative Fuel Sources.

The water fuel cell is a technical design of a "perpetual motion machine" created by American Stanley Allen Meyer (1940 - 1998). Meyer claimed that an automobile retrofitted with the device could use water as fuel instead of gasoline. Meyer's claims about his "Water Fuel Cell" and the car that it powered were found to be fraudulent by an Ohio court in 1996.

Stanley Meyer died suddenly on March 20, 1998, while dining at a restaurant. His brother claimed that during a meeting with two Belgian investors, Meyer suddenly ran outside, saying "They poisoned me". After an investigation, the Grove City police went with the Franklin County coroner report that ruled that Meyer, who had high blood pressure, died of a cerebral aneurysm.

Some of Meyer's supporters believe that he was assassinated to suppress his inventions.
