The Truth about Water for Gas: The Principles Behind The Fuel from Water Process And How It Works.

So exactly how does the water for gas or fuel for water system really work? The basic principles are so simple that I could teach a teenager how to build one on a lazy Saturday afternoon.

What is does Water for Gas mean?

Water for gas is very modern term describing a process that is very old. Water for gas is in part a process of water electrolysis. Invented by Englishmen, William Nicholson and Anthony Carlisle about 1800, water electrolysis has been used to separate plain H2O into its component parts (hydrogen and oxygen) for a over a two hundred years.

Basically you install a prebuilt kit or make one yourself that using your car’s electrical system to separate the hydrogen and oxygen into what is called HHO or Brown’s Gas. This gas is then mixed in with the normal air flow of your vehicle and compressed with gasoline. The ignited gas combusts at lower temperatures which allows the car to burn less gas and save you money by increasing the mileage.

Who invented the Water for Gas System?

Since this process has been around longer than the internal combustion engine, it is safe to say that a whole lot of folks may have had a hand in developing the prcess. But two the pioneers were William Rhodes, an American inventor, who in the 1960s was the first to patent the water electrolysis process into a compact, portable electrolyzer (which he used as an oxy-hydrogen welder).

But the man who gets the most credit is a Dr. Yul Brown from Australia. He also patented a oxy-hydrogen welder but being the better marketer of the two inventors, his design became popular with mechanics and hobbyists worldwide.

And it’s the “Brown’s Gas” or HHO generator that forms the core concept in most the water for gas or fuel from water car kits and designs available on the market today. Brown’s Gas is by volume two parts hydrogen and one part oxygen. This is different from the normal H2 gas available from gas bottlers.

How does it Work?

In a normal 4-stroke engine you have 4 phases (intake, compression, power and exhaust). Air is pulled into the car’s combustion chamber along with a preset spray of gasoline. Together they are compressed, and then ignited with an electrical spark in the power phase, The whole mixture combusts (in a controlled explosion) which powers the car. The carbon byproducts are then released from the chamber during the exhaust cycle.

With the water for gas system, the HHO gas is introduced into the combustion process, mixed in with air. The new gas (air + HHO) is compressed with the gasoline, but since HHO has a lower flashpoint it allows the combustion process to use less gas and this in time saves you money.

Is This Process Safe?
As mentioned before water electrolysis has been in use for over 200 years and is frequently used in tabletop demonstrations in classrooms and science labs around the world. If used properly, a water for gas system should be safe, clean and fuel efficient.
