A Japanese company named Genepax may have pulled ahead of the competition with a prototype vehicle that runs entirely on water and air. And the best part is that it does not emit carbon dioxide.

Their new “Water Energy System (WES),” generates power by supplying water and air to the fuel and air electrodes using a proprietary technology called the Membrane Electrode Assembly (MEA). The secret behind MEA is a special material that is capable of breaking down water into hydrogen and oxygen through a chemical reaction.

Though the company did not reveal the details, it “succeeded in adopting a well-known process to produce hydrogen from water to the MEA,” said Hirasawa Kiyoshi, the company’s president. This process is allegedly similar to the mechanism that produces hydrogen by a reaction of metal hydride and water. But compared with the existing method, the new process is expected to produce hydrogen from water for longer time, the company said.

With the new process, the cell needs only water and air, eliminating the need for a hydrogen reformer and high-pressure hydrogen tank. Moreover, the MEA requires no special catalysts, and the required amount of rare metals such as platinum is almost the same as that of existing systems, Genepax said.

During a recent conference, Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W—and there are plans for a 1kw-class generation system for use in both electric vehicles and houses sometime in the future. At this point, the cost of production on the water-powered vehicle engine itself is around about ¥2,000,000 (US$18,522), but they hope to drop the price to ¥500,000 (US$4600) or less if they succeed in bringing it into mass production.

Well personally I think that this is really good news to both consumer and the environment. With this car, we won’t be too oil reliant and most importantly, its totally green. Oil being $135 per barrel will be a thing of the past.
