TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The steam introduced to the system is produced as by-product of a method for generating hydrogen and/or energy from a chemical reaction including selecting an electronegative half-cell reaction producing hydrogen, selecting a first electropositive half-cell reaction having sufficient potential to drive the electronegative half-cell reaction, selecting a second electropositive half-cell reaction, and combining the half-cell reactions. The first and second electropositive half-cell reactions selected in combination with the electronegative half-cell reaction produce an increase in hydrogen and/or energy production from water. The enhanced energy production system includes a reaction system of half-cell reactions. The reaction system or half-cell reactions require or are assisted by the provision of reactive or catalytic surface. The reaction system includes electropositive half-cell reaction(s) involving metal organic complex capable of changing configuration to release electron(s) in realization of an increased co-ordination number, or involving the oxidation of species, e.g. Group I or Group II metal, binary hydride, ternary hydride, amphoteric element, electropositive elements in Groups I and II of the periodic table and chelated transition elements, oxyacid of phosphorus, and/or oxyacid of sulfur. The reaction system includes the formation of further semiconductive material or molecule, e.g. composite material or molecule. The enhanced energy production system includes an associated heat exchange system that can be used to transfer heat from an exothermic chemical reaction in the cell or control the rate of exothermic chemical reaction(s). Alternatively, the enhanced energy production system includes a two-part process for generating hydrogen and/or energy. The first part is a primary reaction system including the sub-steps of selecting an electronegative half-cell reaction producing hydrogen, selecting a first electropositive half-cell reaction having sufficient potential to drive the electronegative half-cell reaction, selecting a second electropositive half-cell reaction, and combining the half-cell reactions. The second part includes the introduction of steam produced as a by-product of the first step at elevated temperature and positive pressure into an enhanced reactor, where a portion of the energy added to the reactor system by the addition of the steam is used by reaction systems in the reactor to increase the number of dissociated water molecules at or near a reactive or catalytic surface.
