Garrett electrolytic carburetor Charles H. Garrett allegedly demonstrated a water-fuelled car "for several minutes", which was reported on September 8, 1935, in The
Dallas Morning News. The car generated hydrogen by electrolysis as can be seen by examining Garrett's patent, issued that same year. This patent includes drawings which show a
carburetor similar to an ordinary float-type carburetor but with electrolysis plates in the lower portion, and where the float is used to maintain the level of the water. Garrett's patent fails to identify a new source of energy.
Malcolm Vincent's water powered car In 1973, Malcolm Vincent, of Nelson, New Zealand, was the star of a four-minute newsreel about his claim to have invented an engine powered by water. He had fitted a prototype to a car and said he's driven hundreds of miles at speeds up to 60 miles an hour. Vincent told the reporter that the engine works on a hydraulic principle, using an ordinary electric starter to give it an initial thrust.
Stanley Meyer's water fuel cell At least as far back as 1980, Stanley Meyer claimed that he had built a dune buggy that ran on water, although he gave inconsistent explanations as to its mode of operation. In some cases, he claimed that he had replaced the spark plugs with a "water splitter", while in other cases it was claimed to rely on a
"fuel cell" that split the water into hydrogen and oxygen. The "fuel cell", which he claimed was subjected to an
electrical resonance, would split the water mist into hydrogen and oxygen gas, which would then be combusted back into water vapour in a conventional
internal combustion engine to produce net energy. Meyer's claims were never independently verified, and in an Ohio court in 1996 he was found guilty of "gross and egregious fraud". Originally developed as an alternative to
oxyacetylene welding, the company claimed to be able to run a vehicle exclusively on water, via the production of "Aquygen", and invoked an unproven state of matter called "magnegases" and a discredited theory about
magnecules to explain their results. Company founder Dennis Klein claimed to be in negotiations with a major US auto manufacturer and that the US government wanted to produce
Hummers that used his technology. At present, the company no longer claims it can run a car exclusively on water, and is instead marketing "Aquygen" production as a technique to increase
fuel efficiency, thus making it
hydrogen fuel enhancement rather than a water-fuelled car.
Genesis World Energy (GWE) Also in 2002, Genesis World Energy announced a market ready device which would extract energy from water by separating the hydrogen and oxygen and then recombining them. In 2003, the company announced that this technology had been adapted to power automobiles. The company collected over $2.5 million from investors, but none of their devices were ever brought to market. In 2006, Patrick Kelly, the owner of Genesis World Energy was sentenced in New Jersey to five years in prison for theft and ordered to pay $400,000 in restitution.
Genepax Water Energy System In June 2008, Japanese company Genepax unveiled a car it claimed ran on only water and air, and many news outlets dubbed the vehicle a "water-fuel car". The company said it "cannot [reveal] the core part of this invention" yet, but it disclosed that the system used an onboard energy generator, which it called a "membrane electrode assembly", to extract the hydrogen using a "mechanism which is similar to the method in which hydrogen is produced by a reaction of metal hydride and water". The hydrogen was then used to generate energy to run the car. This led to speculation that the
metal hydride is consumed in the process and is the ultimate source of the car's energy, making it a hydride-fuelled "
hydrogen on demand" vehicle rather than water-fuelled as claimed. On the company's website the energy source is explained only with the words "
Chemical reaction". The science and technology magazine
Popular Mechanics described Genepax's claims as "rubbish". The vehicle Genepax demonstrated to the press in 2008 was a
REVAi electric car, which was manufactured in India and sold in the UK as the G-Wiz. In early 2009, Genepax announced they were closing their website, citing large development costs.
Thushara Priyamal Edirisinghe Also in 2008, Sri Lankan news sources reported that Thushara Priyamal Edirisinghe claimed to drive a water-fuelled car about . on of water. Like other alleged water-fuelled cars described above, energy for the car was supposedly produced by splitting water into hydrogen and oxygen using electrolysis, and then burning the gases in the engine. Thushara showed the technology to Prime Minister
Ratnasiri Wickramanayaka, who "extended the Government’s full support to his efforts to introduce the water-powered car to the Sri Lankan market".
Daniel Dingel Daniel Dingel, a Filipino inventor, has been claiming since 1969 to have developed technology allowing water to be used as fuel. In 2000, Dingel entered into a business partnership with
Formosa Plastics Group to further develop the technology. In 2008, Formosa Plastics successfully sued Dingel for fraud and Dingel, who was 82, was sentenced to 20 years' imprisonment.
Agha Waqar Ahmad Pakistani man
Agha Waqar Ahmad claimed in July 2012 to have invented a water-fuelled car by installing a "water kit" for all kind of automobiles, which consists of a cylindrical jar that holds the water, a
bubbler, and a pipe leading to the engine. He claimed the kit used electrolysis to convert water into "
HHO", which is then used as fuel. The kit required use of distilled water to work. Ahmed claimed he has been able to generate more oxyhydrogen than any other inventor because of "undisclosed calculations". He applied for a patent in Pakistan.
Aryanto Misel Indonesian inventor Aryanto Misel claimed in May 2022 that his invention, called Nikuba, can convert water into hydrogen that can be used as fuel for motorcycles. Aryanto claimed that he only required 1 liter of water for the distance of 500 kilometers. In July 2023, Aryanto claimed that Italian-based automobile manufacturers Lamborghini, Ducati, and Ferrari are interested in Nikuba. He also claimed that he is willing to sell the device to foreign companies for 15 billion rupiahs, while also claiming that he didn't need the Indonesian government and National Research and Innovation Agency as they have "destroyed" him. Indonesian scientists from
National Research and Innovation Agency stated that the device is theoretically impossible. They also stated that there is no interest from Italian automobile manufacturers in Nikuba, and Aryanto was invited by their partners instead of the automobile manufacturers. ==Hydrogen as a supplement==
