BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side view of the core apparatus claimed as the invention.
FIG. 2 is a side view of the apparatus claimed, including solar panel and steam turbine.



DETAILED DESCRIPTION OF THE INVENTION
To obtain the objects as noted above the inventors analyzed established and innovative power generation systems with a view to reducing cost and environmental impact of power production. It was discovered that electrolysis has long been acknowledged to be the choice method where hydrogen and oxygen production are required from water, that water breakdown and reformation is adequate to power gasoline fueled engines, that said reformed water may be conducted back to the electrolyzer for a closed loop fuel production and use system, and that no environmentally harmful emissions will result. The invention is predicated in these findings.
More particularly, the present invention features the method of connecting the electrolyzer to the battery system of a vehicle engine or power plant, the electrolyzer chamber being divided with a central partition extending below the water level. This provides a hydrogen chamber in the cathode section, and an oxygen chamber in the anode section. A chimney at the top of each chamber conducts the gases independently to the intake manifold for the engine. The engine, typical of any manufactured by the world automakers, contains sparkplugs of conventional or optical nature which catalyse the reformation of water from hydrogen and oxygen gas. The resultant gas expansion drives the cylinder pistons of the engine as the gasoline explosions drive the cylinder pistons in conventional gasoline combustion engines. The steam water vapor resulting from this water reformation is conducted from the engine, as the gasoline combustion byproducts are conducted from a conventional gasoline engine. Instead of being exhausted to our atmosphere, however, the water vapor is passed through a steam turbine, generating electrical energy which is fed to the battery system. Exiting the turbine, the vapor passes to a thermostat which routes the water vapor to a radiator if the vapor is of too high a temperature to be fed directly back to the electrolyzer. If the vapor is cool enough it is fed directly back to the electrolyzer. A solar panel system connected to the battery assembly provides additional electrical energy to start and maintain the electrolysis process.
Now, preferred embodiments of the invention will be described with reference to the drawings.
FIG. 1 is a side view of the invention, illustrating the primary embodiment. More specifically, the Figure shows an apparatus, which comprises a battery system 1, containing a c cathode 2 and anode 3. Cathode 2 is connected by wire 4 to hydrogen generating electrode 7. These electrodes 6 and 7 are contained within electrolyzer 5, which is filled with water and a 25% sodium hydroxide mixture to level 25. Partition 24 separates the hydrogen produced by electrode 6 from the oxygen produced by electrode 7. Hydrogen is conducted by chimney pipe 8 to the fuel manifold, and oxygen is conducted by chimney pipe 9 to the fuel manifold. Pressure relief valve 11 is provided in case of engine malfunction. The reun reunited hydrogen and oxygen mixture enters the cylinders inside the engine, and are catalysed to react by optical or conventional sparkplugs, one of which is shown as 12. The resultant water vapor exits the engine, as this is a conventional car engine, and passes into exhaust pipes, one of which is illustrated as 13. Exhaust manifold 14 conducts the vapor to thermostat 15, which directs
the vapor to the radiator 16 if the temperature of the vapor is too high to be fed directly into the electrolyzer chamber from where it originated. If the vapor temperature is low enough, the thermostat directs the vapor back to the electrolyzer chamber for another cycle of water dissassociation and reassociation.
FIG. 2 is a side view of another embodiment of the present invention. The components are identical to those in FIG. 1, with the addition of a turbine 20 located on the exhaust manifold 14. The electrical energy produced by the water vapor steam passing through turbine electrical generator combination 20 is conducted by wire 26 to the cathode of the battery system, and by wire 27 to the anode of the battery system. Solar panel assembly 21, placed on the roof of the vehicle or other suitable location, provides electrical energy to the battery system cathode by wire 22, and electrical energy to the battery system anode by wire 23.
