  • Patent number: 5100642
    Abstract: A fuel composed of water, a compound in which free radicals have been generated and a solute that stabilizes the free radicals while the fuel is in the liquid state but which releases the free radicals when the fuel is sprayed (vaporized) so that the free radicals then dissociate the water to form hydrogen gas in sufficient concentration to support combustion. The most readily available compounds in which free radicals can be generated to provide the fuel are hydrocarbons and carbohydrates. Free radicals may be generated in solids (e.g., sugar) by charring and grinding the sugar then mixing with acid. Free radicals may be generated in liquids by adding an acid. Polar liquids such as alcohols, aldehydes and ketones have been found to be the most effective stabilizers.

  • Patent number: 4625681
    Abstract: A method of obtaining mechanical energy utilizing H.sub.2 O-plasma that is generated in multiple steps. The general field of art of the invention is that of producing a reactive thrust by using plasma. The mechanical energy provided by the invention is produced by explosion of electrically conductive plasma which is generated by dissociating H.sub.2 O. At the first step H.sub.2 O (gas) produced by a gasifier is reduced to a plasmatic state by electrical discharge. At the second step the plasmatic gas is treated by a further and stronger electrical discharge and by high-frequency induction heating, and the energy level of the plasma is raised to a point at which a plasma jet is ready to be produced. At the third step, the plasma jet is generated by periodically modulating the high voltage for the second electrical discharge, and a high-pressure thermal explosion reaction is caused by synchronizing the generation with compression of the plasma jet.

The improvements also provide for a first auxiliary fuel dissociator to dissociate the ammonia utilizing the exhaust heat of the engine and a second auxiliary fuel dissociator to dissociate ammonia until the engine generates sufficient heat for the operation of the first dissociator.

  • Patent number: 4458496
    Abstract: The invention relates to the charging of pressure gas containers used for the storage of hydrogen, on the basis of a gas/solid matter reaction. In the method the container (1) is supported from the outside both on filling and compressing of the storage material (2) and on subsequently charging the material (2) with hydrogen. By this means, deformations of the container wall through expansion of the storage mass or its introduction into the container are inhibited, and the use of larger more economic containers is made possible.

  • Patent number: 4458634
    Abstract: A control system for maintaining a desired water level range from electrodes spaced thereabove in a layer of oil where alternating current discharge occurs from electrode down to and through water to another electrode, with the electrical discharge occurring between electrodes disposed at all times in the hydrocarbon oil layer. With the situs of reaction being confined to the oil and the interstitial boundry between the oil and water, dangerous conditions of hydrogen generation are generally obviated over most state-of-the-art methods of producing hydrogen with a highly efficient production process. Hydrocarbon gases and vapors are also produced from the oil with a cracking process occuring to some extent incumbant with the A C discharge from the electrodes through the oil to the water. This has also been found to gradually upgrade the quality of the oil remaining while some is at the same time consumed in the system.

  • Patent number: 4454850
    Abstract: Process and apparatus for liberation of energy by controlled nuclear fusion reaction involving isotopes of hydrogen gas. Highly ionized hydrogen gas containing a higher proportion of deuterium than in naturally occurring hydrogen is pressurized, together with an oxidizing gas within combustion chamber of reciprocating piston and cylinder engine. An electrical discharge within the combustion chamber causes generation of heat by atomic dissociation and exothermal recombination of hydrogen atoms and electrical excitation of ionized gas. Ionized deuterium in the hydrogen gas undergoes a nuclear fusion reaction with consequent liberation of heat energy and remaining hydrogen gas burns in the oxidizing gas to provide control on fusion reaction. Apparatus for producing ionized hydrogen gas in appropriate form by treatment of normal industrial hydrogen gas is disclosed, and also gas mixing apparatus for mixing the ionized hydrogen with atmospheric air as the oxidizing gas.

  • Patent number: 4442801
    Abstract: A combustion engine is provided with a fuel supplementation system in which water is broken down by electrolysis into hydrogen and oxygen which are then added to the fuel delivery system. The electrolysis takes place in a chamber in which a pusher gas rises through perforated horizontal electrode plates to sweep the hydrogen and oxygen from the plates as it is generated, thereby preventing the accumulation of these gases in the chamber. In addition, the electrolyte can be circulated, passing it through a filter, to increase the turbulence and agitation within the chamber. The rate at which the water is electrolyzed is varied, as by modulating the voltage applied to the plates, in accordance with the throttle position of the engine. Since gases do not accumulate in the chamber, variations in the rate at which these gases are yielded are affected substantially instantaneously. Lignite activited water can be added to the electrolyte to inhibit the formation of sludge.
