The definition of a water-fuelled car is a vehicle that runs on a motor that is fuelled without any other energy source than water. The compound of water is made of two parts hydrogen and one part oxygen. The use of water to make a fuel has, up to this point in time, been simply a science fiction dream.



A common belief of water-fuelled vehicles is that a form of this is a steam engine. This is not true as the steam engine uses wood or coal to heat up the water to form steam. That fuel source is then the wood or coal not the water.

Water is not an easy substance to convert into fuel, as it is a waste product not a substance that can be burned. Substances that can be burned, such as wood or petrol, emit energy from the burning. That change from unstable bonds to stable bonds cannot be applied to water, as water is already a stable bond.

The only two ways that water can truly become a fuel is either by adding a high-energy compound to it or by electrolysis. Adding a high-energy compound to water allows it to be converted into energy through releasing its bonds. Electrolysis is a change of water to energy by introducing electricity to the water.

This electrical charge placed in the water separates the bonds. The hydrogen in the bond is then used as the energy source. It would take quite a bit of power to separate enough water bonds to create energy.

The size and power of a battery powerful enough to run a vehicle from the electrolysis of water is so immense that it is not a probable solution. The efficiency of the conversion using electrolysis is between 50-70%, however the power of the hydrogen would be only about 30%. Therefore, it would be more efficient to simply run the vehicle from the power of the battery.

The first and second laws of thermodynamics have barred many inventors' ideas from becoming reality. These laws have reduced many inventions into the classification of perpetual motion vehicles instead of true water-fuelled vehicles. In addition, many have discovered the true fuel behind the so-called water-fuelled vehicles were actually other sources, due to the two thermodynamics laws.

Many men have tried many different variations to overcome the power of the thermodynamics laws. However, each has failed. Within these failures, two very notable men claimed to have discovered the truth behind water-based fuel.

Stanley Meyers' creation has gone down in history books as a hoax. He had claimed to invent the first true water-fuelled car but it was discovered that he hadn't invented anything new. His "patent" subtly overlooked describing how water was the fuel of the vehicle.

The machine he created was simply a perpetual motion machine and nothing more. Henry Garrett on the other hand had created a vehicle that was run by water. However, his invention was not the engine itself but a carburetor, therefore the actual energy source was the battery.

There have been reports in many magazines and newspapers about a Japanese invention that is a water-fuelled engine. It does not have a patent as of yet. Once the patent is given, then it will be discovered whether this is a true water-fuelled engine or just another reinvention of the wheel.
