In June 2008 Japanese company ''Genepax Water Energy System'' presented an electric ''water-fuel car'' (Reva) claiming that it could be operated by water and air alone and would need only one liter water from any water source for an one hour drive with 80 km/h . The exact nature of the energy source was not revealed by Genepax and the manufacturer refers for its Water Energy System (WES) just to an unspecified "energy generator", which is claimed to be able to split hydrogen from water using some kind of metal hydride and a "chemical reaction". Hydrogen gas is then used as fuel.

In June 2008, a Japanese company by the name of ''Genepax Water Energy System'' presented an electric ''water-fuel car'' (Reva) claiming it could be operated by water and air only and needed no more than one litre of water from any water source for a one hour drive at 80 kms/h. Genepax did not reveal the exact nature of the energy source and manufacturers just refer to an unspecified "energy generator" for its Water Energy System (WES), which allegedly is able to split hydrogen from water using some kind of metal hydride and a "chemical reaction". Hydrogen gas is then used as fuel.

The product of the reaction is again water. This principle would make it a [[Perpetual Motion|perpetual motion]] device. With alkali metals(sodium) hydrogen may be won from water: Alas, this would not only set the hydrogen free; the oxygen would be bound to the metal and could not be used. During operation, the metal hydrid would be used up and serves as the actual energy source. It has to be created by using energy. So, the car is not powered by some wonderous energy from water, it is powered by a primary battery.<ref>http://www.inteldaily.com/?c=120&a=7157</ref> Professional journals like ''Popular Mechanics'' called the alleged wondercar "Rubbish"<ref>http://www.popularmechanics.com/automotive/new_cars/4271579.html</ref> and professional circles ignored it. The website genepax.co.jp was abandoned in february 2009. [[Matthes Haug]] still advertises Genepax as a car which ''drives with water''.
