List of pseudoscientific water fuel inventions
This article attempts to list pseudoscientific inventions wherein common water is used to either augment or generate a fuel to power an engine, boiler or other source of power. This is not to be confused with legitimate inventions (such as hydroelectricity) in which the kinetic energy of flowing water is used for power.
The electrolysis of water splits water into hydrogen and oxygen, producing a usable fuel. However, the energy required for electrolysis is greater than the energy released by burning this fuel, so this is not a viable way to manufacture energy. Nonetheless, several people have claimed to create devices that do exactly this.
- Francois Cornish, a French inventor whose 1987 US Patent describes how to make hydrogen fuel for a vehicle on-demand with an underwater aluminum wire arc design. See also U.S. Patent 4,702,894.
- Stanley Meyer, who claimed to run a car on water in 1984.
- Charles Frazer, an Ohio inventor who, in 1918 patented a hydrogen booster which claimed to use electrolysis to increase vehicle power and fuel efficiency while greatly reducing exhaust emissions.
- Daniel Dingel, a Filipino engineer who has been involved in water fuel research since 1968. A video interview showed Dingel's Toyota Corolla with an on-board hydrogen water fuel generator. This research career may be curtailed by his recent 20 year sentence for fraud.
- Henry and Charles H. Garrett's electrolytic carburetor.
- Paul Pantone. GEET reactor. 
- Ruggero Maria Santilli's "Magnegas" recyclers, which use an underwater carbon arc to gasify bio-contaminated liquid into a clean-burning gas.
Water is claimed to be transformed into a fuel itself, by the addition of some ingredient. This may be either a highly concentrated addition, or a catalyst (i.e. not consumed in use).
The 1989 experiment by Fleischmann and Pons claimed to demonstrate "anomalous heat production" in an electrolysis cell. This is distinct to the "super-efficient electrolysis" claims listed above. The likelihood of the Fleischmann and Pons experiment is that it was no more than measuring error in determining the energy (and thus heating) supplied to the experiment.
