NOVELTY - An electrical current is produced in closed system by splitting first substance into by-products via first electrochemical reaction in reservoir (102) containing electrode(s) (106, 110), introducing by-products into reactor vessel (118) such that each by-product enters the vessel at separate locations, transferring by-products past a first generator positioned in reactor vessel to generate first electrical current, and recombining by-products to form first substance via second electrochemical reaction.    USE - The method is used for production of electrical current in closed system by electrolysis of water (claimed); or for electrolysis of oxygen rich methane to produce carbonic acid, or liquids to form other liquids.    ADVANTAGE - The system can produce enough electrical current to sustain itself, and additional current to be converted and/or transformed for consumption by an outside source.    DETAILED DESCRIPTION - Production of electrical current in closed system comprises:    (A) splitting first substance into by-products via first electrochemical reaction in reservoir (102) containing electrode(s) (106, 110), collecting each by-product in separate chambers, and introducing by-products into reactor vessel (118) such that each by-product enters the vessel at separate locations;    (B) transferring by-products past a first generator positioned in reactor vessel to generate first electrical current, and recombining by-products to form first substance via second electrochemical reaction; and    (C) transferring recombined first substance past a second generator positioned in return path between reaction vessel and reservoir to generate second electrical current, and reintroducing first substance into the reservoir.    An INDEPENDENT CLAIM is included for a closed system for producing electricity comprising:    (1) reservoir with first chamber including first electrode and first exit pathway (112), second chamber including second electrode and second exit pathway (114), and input port, where an electrolytic solution containing a fluid substance is contained within reservoir;    (2) reaction vessel having first input port, second input port and output port;    (3) water column having first end operably coupled to output port of vessel and second end distal the first end operably coupled to input port of reservoir; and    (4) paddle wheel positioned within water column between first end and second end.    The first exit pathway is operably coupled to first input port, and second exit pathway is operably coupled to second input port. A first gas is produced from electrolytic solution in first chamber and enters reaction vessel at first input port. A second gas is produced from electrolytic solution in second chamber and enters reaction vessel. The first gas recombines with second gas in reaction vessel to reform fluid substance, and fluid substance exits reaction vessel at output port into water column past paddle wheel, causing the paddle wheel to rotate.
