Kereta menggunakan air kini diusahakan oleh banyak syarikat dan negara merupakan kereta alternatif kepada kereta yang menggunakan bahan bakar konvensional dan mesra alam. Terbaru sekali Jepun telah berjaya memperkenalkan kereta air yang paling praktikal melalui syarikat Genepax dengan menghasilkan kereta yang menggunakan air sepenuhnya.
Dalam demonstasi awal yang diadakan di Osaka pada 12 Jun, dua hari sebelum diadakan Kumcakan Kumpulan 8 (G-8/Amerika Syarikat (AS), United Kingdom, Jepun, Perancis, Jerman, Itali dan Rusia) di bandar raya yang sama untuk membincang isu krisis bahan bakar dan makanan, kereta Genepax bukan saja dapat mempromposi dengan jaya, tetapi menjadi tamparan kepada negara-negara maju Barat itu. Ini kerana walaupun teknologi kereta air itu sudah lama ditemui dan banyak syarikat di negara-negara maju berkenaan telah membuat pelaburan besar-besaran terutama di AS, tetapi keteta air mereka tidak praktikal untuk digunakan oleh masyarakat kerana komplikated dan menyusahkan.
Tetapi kereta Genepax selain jimat dan mersra alam, ia juga mudah untuk digunakan. Malah jika membanding dengan kereta air negara-negara lain, ia adalah yang paling mudah, praktikal dan tercanggih kini.

1- Japanese Firm Demonstrates Car That Runs On Water
Friday June 13, 2008
If you’re tired of spending money like water on gas, maybe you’d just rather spend money on water, period. That’s what you’ll be doing if a Japanese firm has its way.
A company called Genepax, dedicated to finding ways to turn water into power, has unveiled what it calls the first practical car to run solely on H20. The firm claims putting just a litre of water from any source – tap, rain or river – is enough to keep its automobile going for 60 minutes at a respectable speed of 80 kilometres an hour. And forget about finding a gas station when you’re running on empty.
“The car will continue to run as long as you have a bottle of water to top up from time to time,” Genepax CEO Kiyoshi Hirasawa told a local Japanese broadcaster after demonstrating the test vehicle in Osaka. “It does not require you to build up an infrastructure to recharge your batteries, which is usually the case for most electric cars.” According to the company, the water gets poured into a tank at the back of the car and uses a generator to break it down and convert it to electrical power.
It’s a completely different approach from the big automakers, who are looking at fuel cells that run on hydrogen as the next power source. Ironically, they emit water from the exhaust, not use it to run the vehicle. Genepax can’t say yet when you’ll be taking one of their cars for a spin but like all these future fuels, their arrival seems to be off in the distance. They’ve just applied for a patent on the system and can’t say when – or if – it will ever actually hit the showrooms.
But they’re in talks with Japanese automakers about the idea and hope it will one day water down your need to ever visit a gas station – with its non-stop climbing prices – again.
2- Running a car on water has been the holy grail for car manufacturers for some time now, but it appears that a Japanese company named Genepax may have pulled ahead of the competition with a prototype vehicle that runs entirely on water and air. 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.
Not surprisingly, Genenpax has kept the exact details of their technology under wraps, but they did say that their new process, while based on existing technology, is expected to produce hydrogen from water for longer time than any method currently available. Furthermore, WES does not require a hydrogen reformer, a high-pressure hydrogen tank, or any special catalysts to get the job done.
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.
3- If there just isn’t enough oil to go around, then let’s turn our energy needs to something that is overly abundant on the planet. Water seems like a good choice for an energy source, and many have tried. It looks like Genepax Co, a Japanese company, has been able to get a car to run on water.
The engine gets its power by supplying water and air to the fuel and air electrodes. What’s really happening is that this is nearly a hydrogen powered car, but you don’t need to find the one or two lonely hydrogen refueling stations. Genepax has created what they call a “membrane electrode assembly” (MEA) that is able to break water down into hydrogen and oxygen using a chemical reaction. I’m not sure how it works exactly, and Genepax isn’t saying, but they claim their process can produce hydrogen for a longer time. My favorite part about this little car is that you don’t need to have a pressurized hydrogen tank sitting in the back of your vehicle.
Forget about how difficult it would be to refuel, why would I want a bomb in my trunk? I’m far more comfortable with a few jugs of water that get split up during the driving experience. It’s really too bad that being in the northeast eliminates many of these smaller, energy efficient, cars from practical use. Although I did see an electric car yesterday…I’ll have to make a note to ask those people how it handles come the blizzards in December. The cost of the engine itself is around $18,000, which puts this little car on the impractical list.
But Genepax hopes that if it can go into mass production the cost will reduce down to as little as $4,600. Kiroshi Hirashawa, head of the company GENEPAX said: “The main characteristic of this car is it will continue to run as long as you have a bottle of water inside for you to ad from time to time.”According to the Japanese company, one litre of water keeps the car running for about an hour at a speed of 80 kilometers an hour
