Why are all our cars still running on gasoline or on batteries that have to be plugged in to the mains for charging?

Water is composed of hydrogen and oxygen. Both of them burn separately in air, and when they do so together, the heat of combustion is greater than that of a pure gasoline air mixture.

United States Patent #2,006,676  for a device to enable burning water to power a car was issued way back in 1935 to C.H. Garrett, so water powered cars are long overdue.

Another separate U.S. Patent to burn water in cars was issued in September 1976 to an Australian/Hong Kong conglomerate (Details in the Cejka Files, DVD and document CD). 

And yet another Patent for burning water in cars was issued in 2004 to a Canadian group.  The truth is, there are a whole host of these Patents for burning water.  And there are also a number of U.S. inventors that have produced water burning cars, including Stanley Meyer and Denny Klein

In fact, inventor Denny Klein of Clearwater, FL had an invention for burning water that was so interesting that it was taken up with the U.S. Congress, and the U.S. Military were interested in him developing a water powered Hummer SUV for them.

Even the Japanese demonstrate their water burning car on National TV.
