| 20090266706 | HIGH ELECTRIC FIELD ELECTROLYSIS CELL - A High Electric Field Electrolysis (HEFE) cell is provided for electrolyzing water to transform it into Free Radical Solution (FRS) water for cleaning, deodorizing, and sterilizing. The HEFE cell is comprised of a pair of flat electrodes attached (or coated) onto a flat proton ion exchange membrane enclosed in a corresponding structure that accommodates the electrodes and the proton ion exchange membrane. The structure is comprised of at least one inlet channel for receiving purified water and two outlet channels for output of electrolyzed FRS water and hydrogen rich water. The HEFE cell further provides a mechanism for recycling of hydrogen rich water for re-use or electric power generation. The quantity and the quality of FRS water production is controlled with an external control circuit that automatically monitors and maintains appropriate parameter values for the production of FRS water. | 10-29-2009 |
| 20100206721 | ON DEMAND HYDROGEN ENHANCEMENT SYSTEM FOR INTERNAL AND EXTERNAL COMBUSTION ENGINE - The objective of this invention, on demand hydrogen enhancement system for internal and external combustion engine, is to develop a continuous non pressurized water electrolyzer from clean water (not pure water or distil water) generator system. The mixed hydrogen gas and oxygen gas called “Oxyhydrogen”. Oxyhydrogen use as catalyse for internal and external combustion engine to increase fuel flame speed. It can use with variety fuels such as Ethanol, Methanol, Gasohol, Gasoline, Diesel, Bio Diesel, LPG, CNG, and LNG. This system can reduce fuel consumption, increase fuel efficiency, increase torque, reduce emissions, and reduce engine temperatures. The system required no cooling fan and electrolytic solution circulating pump. The system has less heat loss and very low electrical consumption. Oxyhydrogen will produce on demand as the engine RPM and load of generator. The control unit detects signal frequency from the alternator. Gas production rate low at low RPM and use less current and gas production will high at high RPM and use higher current. This can save lot of energy for the electrolysis process. In the past, water electrolysis use direct current (D.C.). In this invention the inventor uses D.C. with Frequency Modulate (FM) pulse width modulator (PWM) instead of Amplitude Modulator (AM) to control the electrolyzer (FMPWM). This circuit had current detector for automatic current adjustment and over current protection. | 08-19-2010 |

| 20120222953 | Systems and Methods for Producing Pressurized Gases from Polar Molecular Liquids at Depth - A system for producing pressurized gas(es) from polar molecular liquids without the need to compress the gas(es) through outside mechanical forces or through the use of electrical energy or otherwise. The system incorporates an electrolysis cell positioned at depth (greater than 16 feet) within the liquid. The electrolysis cell includes a bell shaped enclosure defining a gas generating assembly that is positioned at depth within a fluid such as water. The gas generating assembly includes first and second electrodes positioned in spaced relationship and a bell shaped collection vessel arranged above the electrodes. At least one collection vessel includes at least one gas port configured to connect to gas conduits to carry the pressurized gas(es) to the point of use or storage. At least one electrical conductor extends from a power source to at least one of two electrodes positioned within the gas generating assembly. At least one gas collection and storage tank is preferably positioned at the surface to receive and store the produced pressurized gas. Positioning the gas generating assembly at depth immerses the electrodes within the polar molecular fluid, and operation of the electrical power supply establishes an electrical potential between the electrodes resulting in an electrolytic breakdown of the polar molecular fluid into its constituent components. The gas thus collected at the surface may be stored or used immediately in a number of different applications. | 09-06-2012 |
