Water-fuelled cars have been a topic of fascination for decades, with the first water carburetor being demonstrated in 1935. However, the idea that water can be used as a fuel source for cars is largely considered a hoax or myth. Despite this, numerous individuals and companies have claimed to have invented water-fuelled cars, often attracting significant attention and investment. While water cannot be used as a direct fuel source, it can be used to produce hydrogen through electrolysis, which can then be burned as fuel. This process, however, requires more energy input than can be derived from the hydrogen produced, making it impractical as a sole fuel source for cars.

What You'll Learn
Water-fuelled cars are scientifically impossible
The idea of a water-fuelled car is not a new one. As far back as 1935, G. H. Garrett allegedly demonstrated a water-fuelled car for several minutes. More recently, in 2002, Genesis World Energy announced a device that would extract energy from water by separating it into hydrogen and oxygen and then recombining them. However, the project never came to fruition, and the company's founder, Patrick Kelly, was arrested and charged with securities fraud. In 2008, Japanese company Genepax unveiled a car it claimed ran on only water and air, but it never came to market.
The usual method proposed for a water-fuelled car is to separate water into hydrogen and oxygen through electrolysis and then burn the hydrogen or introduce it into a fuel cell to generate a current that runs an electric motor. However, this process requires more energy input than can be derived from the hydrogen. While it has been proposed that this energy could come from solar power, the problems with this version of a water-fuelled car have proven too big to overcome.
Another idea proposed by Stanley Meyer was a "water fuel cell", which he claimed could split water into its component elements of hydrogen and oxygen, with less energy than was conventionally predicted or measured. However, these claims were later found to be fraudulent, and his device was found to be using conventional electrolysis.
In conclusion, while the idea of a water-fuelled car is appealing, it is scientifically impossible due to the laws of thermodynamics and the amount of energy required to separate water into its component elements.

Hydrogen fuel enhancement
There have been numerous claims of cars that run exclusively on water or a mixture of water and conventional fuel. In 2002, Genesis World Energy announced a breakthrough device that would extract energy from water by separating hydrogen and oxygen and then recombining them. The company claimed that this technology could power automobiles. However, the devices were never brought to market, and the founder was charged with fraud. In 2008, Genepax, a Japanese company, unveiled a car that it claimed ran on only water and air.
The concept of hydrogen fuel enhancement involves using hydrogen as a supplement to traditional hydrocarbon fuels. This can be achieved through various methods, such as producing hydrogen through electrolysis, storing hydrogen on the vehicle as a second fuel, or reforming conventional fuel into hydrogen. Hydrogen is referred to as a "clean" fuel because when it reacts with oxygen, the only product is water vapour. Additionally, hydrogen has a strong resistance to auto-ignition, making it a safe alternative.
Despite the many claims and innovations, there is still skepticism and controversy surrounding the idea of water-fuelled cars. Many tests by consumer watch groups have shown negative results, and it is argued that the concept violates the laws of thermodynamics. The process of electrolysis, which is often proposed for water-fuelled cars, requires more energy to separate hydrogen and oxygen than can be gained from burning the produced hydrogen. Additionally, modifications to the engine's subsystems, such as the air-fuel ratio and ignition timing, may be required for hydrogen fuel enhancement to have any significant impact.
While the idea of water-fuelled cars or hydrogen fuel enhancement is appealing due to its potential environmental benefits and increased fuel efficiency, it has not been successfully commercialized. The challenges of transporting, storing, and producing hydrogen, as well as the potential violation of laws and negative impacts on engine performance, have hindered the widespread adoption of this technology.

Water as a working fluid, not a fuel
Water-fuelled cars are not possible according to the currently accepted laws of physics. Water is highly stable and contains very strong chemical bonds. Breaking those bonds will always take more energy than you can get back.
However, water can be used as a working fluid, not a fuel. Water (in both liquid and gaseous forms) can be used as a working fluid in steam cars. Steam cars use steam as a working fluid, not as a fuel. Steam is produced by the reaction of water with natural gas, which is mostly methane. This process produces carbon dioxide along with hydrogen, referred to as "grey hydrogen". If the carbon dioxide is captured without being released into the environment, it is called "blue hydrogen". The ideal is "green" hydrogen, which is made without any carbon dioxide being produced. This can be achieved if hydrogen is produced by electrolysis, with electricity coming from renewable sources such as solar panels, windmills, or nuclear power plants.
Hydrogen fuel enhancement is another way to use water as a working fluid, where a mixture of hydrogen and conventional hydrocarbon fuel is burned in an internal combustion engine to improve fuel economy or reduce emissions. Hydrogen fuel enhancement does not use water as a fuel but rather as a working fluid to enhance the combustion of conventional fuels.
Additionally, water can be used as a working fluid in hydroelectric power plants to generate electricity that can be used to charge electric cars. This is another way to utilize water indirectly as an energy source for automobiles without using it as a fuel.

Electrolysis and the energy output
Electrolysis is a chemical process that involves using electricity to break water down into its constituent elements, hydrogen and oxygen. This process dates back to the early 1800s and is derived from Alessandro Volta's invention of the battery.
In the context of water-fuelled cars, electrolysis is proposed as a way to generate hydrogen fuel from water. The basic idea is to use electricity to split water molecules into hydrogen and oxygen, and then burn the hydrogen to power the car. The oxygen and hydrogen can also be recombined in a fuel cell to generate electricity directly.
However, the problem with using electrolysis to power cars lies in the energy output. The process of breaking water molecules into their constituent elements requires a significant amount of energy input. In fact, it takes more energy to break the strong chemical bonds in water molecules than can be extracted from burning the resulting hydrogen. This violates the laws of thermodynamics, which state that the energy output of a system cannot exceed the energy input. Therefore, a "water-powered" car in this sense is not truly powered by water alone, as it requires an additional energy source to perform the electrolysis.
While electrolysis-based water-fuelled cars may not be feasible due to energy output limitations, it is worth noting that hydrogen fuel cell cars, which use hydrogen as a fuel source, are already on the roads. These cars utilize hydrogen fuel cells to generate electricity and power the vehicle, and they are considered a more realistic alternative to traditional fossil fuel-powered cars.

Water-fuelled car hoaxes
Numerous individuals have made fraudulent claims about inventing water-fuelled cars. In 1980, Stanley Meyer claimed to have built a dune buggy that ran on water, but he provided inconsistent explanations and was later found guilty of fraud in an Ohio court. In 2002, Genesis World Energy announced a device that could extract energy from water, but the technology never came to market, and the company's owner, Patrick Kelly, was sentenced to prison for theft and fraud. In 2008, Genepax unveiled a car claimed to run on water and air, but it never gained traction.
In 2011, Ghulam Sarwar claimed to have invented a car that ran on 60% water and 40% diesel, promising to eliminate diesel completely by 2012. However, this invention also never materialized. That same year, Agha Waqar Ahmad from Pakistan claimed to have invented a "water kit" that allowed cars to run solely on distilled water. Ahmad's claims fooled millions, but he had no engineering degree, and his "discovery" was exposed as a hoax. He disappeared and was never heard from again.

Frequently asked questions
A water-fuelled car is a vehicle that uses water as its primary fuel source. The water is typically converted into "HHO" (a combination of hydrogen and oxygen) through electrolysis, and then used as fuel.
Water-fuelled cars use electrolysis to convert water into its constituent elements, hydrogen and oxygen. The hydrogen is then burned to power the car.
Water-fuelled cars are often promoted as a zero-emissions design. However, this is not entirely accurate as the electrolysis process requires fuel, which may produce emissions. Additionally, the combustion of hydrogen and oxygen produces water vapour, which is considered a form of emission.
