The idea of a water powered car has been around for quite some time and everyone
must have heard this suggestion in the past. The fact is designs for water
powered engines have been around for 70 years.
The first such car was demonstrated by Charles H. Garrett in 1935, which
reportedly ran for several minutes. The car essentially only had a modified
carburetor that included electrolysis plates in the throat of the carburetor.
This foray into water fueled cars was reportedly relatively unsuccessful for
some unknown reason and research was halted.
The science behind water powered cars is usually through electrolysis of the
water to produce a mixture of Hydrogen and Oxygen (called oxyhydrogen, HHO or
Brown’s Gas). This gas is then combusted to produce energy.
The overall process can be represented by the following chemical equations:
The theory has not only been applied to
water powered cars but also hybrid cars,
which continue to use petrol but use water as a supplement to increase mileage.
Around 1970, Yull Brown developed technology which allows cars to burn fuel more
efficiently while improving hazardous emissions. In Brown’s design, a hydrogen
oxygen mixture (so-called “Brown’s Gas”) is generated by the electrolysis of
water, and then fed into the engine through the standard air intake system.
