Since Roger Billings (honored "hydrogen man"; and "Dr. Hydrogen" by Time magazine 2003) built the very first hydrogen car back in 1965, hydrogen cars have come a long journey. You could simply walk into a store and purchase a:
• BMW Hydrogen 7
• Mercedes-Benz F cell
• GM Hy-wire or a
• Mazda RX-8 Hydrogen RE
However the price tags of these cars are currently way over the reach of the average American citizen. Fortunately, recently scientists have created a "conversion kit" thanks to an nearly a century old patented technology that was under the radars (or that WAS FORCED to stay under the radars). This conversion kit makes it possible for regular cars, vans, SUVs, or even trucks, both petrol and diesel, to be converted to run on hydrogen.
The MAGIC KIT
It's slightly different from Roger Billings' hydrogen vehicle, because these cars don't need a hydrogen storage. This new conversion technology makes hydrogen onboard only when necessary and therefore known as ‘Hydrogen On Demand’ (HOD) technology. Another difference with HOD is that it doesn't power the engine totally on hydrogen, but simply supplements the power of. This technology has been patented over 45 times by various scientists; the very first patent overmore than 70 years old. A few examples are: United States Patent 4,573,435 (Glen Shelton: Apparatus and method for generating hydrogen gas for use as a fuel additive in diesel engines); US Patent 4,380,970 (Roy Davis: Combustion engines); and US Patent 4,256,060 (Donald Kelly: Manifold hydrogen generator units for automotive I.C. engines).
Advantages of conversion
Because there are claims of doubling of mileage in Corollas, 60MPG Ford Escorts so on and so forth with HOD technology!
OBVIOUSLY, I found the whole concept pretty disturbing and hard to believe. But then again, I knew that "everything that sounds too good to be true isn't necessarily fake". In the 19th century, people wouldn't have believed that man will ever go to the moon or would read an article on a computer monitor just like you're doing just now, but did it not happen?
That's why I started to research on HOD and this is a glimpse of what I found:
• President George Bush talking about Hydrogen on CNN
• Fox talking about it
• WYFF4 news item about it
• MSNBC news item about it
• Iceland's buses running on hydrogen
• 2200 Japanese homes are powered by hydrogen
• Denmark has a hydrogen power plant

I am a man of SCIENCE, thus wasn't prepared to believe all the sales pages. The technology was made available in the public domain in 2006 and since there has been a flood of HOD conversion kits to the market. Some are fakes; some promise more than what they can provide; and some work just fine. Water4gas is one such product. Saving as much as 35-45% of the gas costs is possible, but don't believe everything you read. Make a scientific decision, read all about it's SCIENCE with over 20 references and proof, including shocking research from the MIT, US AIR FORCE and statements by NASA on http://www.water4gas-scam.com
