NOVELTY - A hydrogen reactor has parallelepiped shaped housing (1) and lid assembled together as closed vessel. The housing is made of titanium sheet approximately which is 3 to 5 millimeter thick. The housing/corpus functions as catalyst in generating hydrogen in the reactor. A positive charge is applied to lid while negative charge is applied to housing/corpus. An electrostatic field occurs in reactor in order to process movement of positively and negatively charged ions in different directions. The negatively charged hydrogen ions move towards positively charged lid with hydrogen outlet.    USE - Multifactorial hydrogen reactor used in internal combustion engine for generating hydrogen from water decomposition reaction in e.g. trucks and small vehicles. Can be used in energy sector, automotive industry, home appliances, waste treatment, environment, health, safety and community development.    ADVANTAGE - Multifactorial hydrogen reactor is provided to improve the fuel efficiency and performance of the internal combustion engine, and as well as improve the production of electricity. Enables hydrogen reactor to perform hybrid conversion in internal combustion engines to save on gas. Hydrogen is produced in hydrogen reactor from water unlike fossil fuels. Use of hydrogen reactor lowers fuel consumption and saves on combustion of fuel. Hydrogen produced by hydrogen reactor does not require any storage and it does not require any contained pressure in heavy cylinders like compressed natural (CNG). Achieves huge increase in fuel savings since trips to gas station are reduced when hydrogen reactor is used on trucks and small vehicles. Specific heat of hydrogen can lower the moisture content from 50% to 30% of unburned garbage because hydrogen burns faster and hotter which helps to boost combustion of garbage completely, and if hydrogen reactor is coupled with solar, it will increase the hydrogen production efficiency. Hydrogen reactor is 100 percent carbon free. Use of Hydrogen Reactor solves and lowers hazardous air pollutants and gas emissions of particulates related to coal and diesel. Hydrogen reactor can work with all types of fuel including Gasoline, Propane, Natural Gas, Coal, Clean Coal, Diesel, Biofuel, Bio diesel, Biomass, Ethanol, Solar. Produced hydrogen from Hydrogen Reactor will boost internal combustion engine's performance while preventing smog and damage on the engine. People can benefit from the Tax refunds owed to them by law for using green technology. Multi-process Hydrogen Reactor development will bring new discoveries, new products and services to the market.
