It was a dream for all people to have a car which can run on water. Especially today, with these kind of gas prices. Well it's not a dream anymore.
Japanese company Genepax claims to have invented a fuel cell system that uses water to obtain hydrogen. It has shown last week two devices, a 120 W fuel cell stack and a 300 W fuel cell system that powered a REVA based minicar. The little car can run at 80 km/h using only a litre of water, but any kind of water, even from the sea. - Continued after the jump...

But it is just a claim for now. Because critics claim that this is impossible because it contradicts the First Law of Thermodynamics, which states that “the increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings”. In other words, the energy that would be necessary to break the water molecules would be higher than what WES would generate for the car’s electric engine, hence the energy would come from somewhere else. A battery, for example.
So there is a good chance Genepax is a big liar. If not, it will have created something mankind has been seeking for a long time: the perpetual motion engine. Since all the car needs to run is water, and since the product of hydrogen reactions in the fuel cells is also water, the WES system could refuel itself with what it generates and could run forever with the same quantity of water. Hopefully Genepax has had a major breakthrough, but that does not seem to be the case for now.
