I'm sure you have heard of how thousands of drivers around the world today are using water fuel cells on their cars and trucks to save on costly gasoline. The popularity of such fuel cells have in fact surpassed that of converting your car to run on compressed natural gas (CNG). And there is a clear reason why - it's much more affordable.

While doing a CNG conversion on your ride may set you back thousands of dollars, water fuel cells can be made from home on your own. All you need is a great set of instruction guides to help walk you through the steps, and a few materials that you can easily get from your garage or local hardware store. All in all, it will not cost you more than $200 for both the instruction manual and the parts.

There are many websites out there offering various instruction guides on how to convert your car to run on water fuel. Some of these guides are designed solely with beginners who have never explored the car engine before, with clear photographic guides on how and where to attach the different parts of the water fuel cell system. This was very useful for me, even though I was a trained vehicle mechanic in the army - after all, I did not want to risk messing up my beloved Mazda.

The process of building a water fuel cell proved not such a daunting task after all. After gathering the materials required (helped with the fact that my instruction guide gave me tips on where to obtain certain parts), it took me approximately just over the weekend to complete the project. And there I was seeing an improvement in my car gas consumption the week after.

How much gasoline was I saving? My gas consumption went up from 13.5km/l to an average of 19km/l - that is a whopping 40% increase in fuel efficiency! While I am satisfied with the current results, I am tempted to try achieve a better result one day, as the system that I learned to build allows me to tweak the settings further.

Here is some advice: While many of the instruction guides available on the Internet are genuine, there are a splatter of scam programs out there to cheat you of your money. So do your research, read the reviews from people who have used the guides on offer, and purchase wisely.

Because most instruction guides are delivered in digital format (meaning you can download it right after the online transaction is complete), you can start building a water fuel cell for your car and start saving money on gas almost immediately.

So what are you waiting for?
