ADVANTAGE - The aluminum-alkali hydroxide recyclable hydrogen generator provides safe and efficient hydrogen source that does not require the expensive infrastructure of compressed or liquid hydrogen, controls the reactant-limited chemical reaction between aluminum, alkali metal hydroxide and water to produce hydrogen gas when and where needed by a consuming apparatus, and safely delivers its hydrogen on demand as needed at atmospheric pressure.    DETAILED DESCRIPTION - The aluminum-alkali hydroxide recyclable hydrogen generator (100) comprises an aluminum source (102), a hydroxide source, a water source (108), a reaction chamber (102) for producing hydrogen from the aluminum, hydroxide and water in a reactant-limited chemical reaction, a flow control mechanism for controlling a flow rate of the solution, a binder release mechanism used to release the binder from a mixture, a control mechanism for controlling an amount of aluminum, the hydroxide or the water in the reactant-limited chemical reaction, a heat source to speed the initial rate of reaction, a heat exchange mechanism for receiving heat produced by the reactant-limited chemical reaction, a thermoelectric generator that receives heat from the heat exchange mechanism and produces electricity, a hydrolysis cell that receives electricity from the thermoelectric generator, a waste reservoir (118) for receiving a waste solution from the reactant-limited chemical reaction, a precipitator that precipitates aluminum hydroxide from the waste solution, an alumina generator that heats the aluminum hydroxide to generate alumina and water, an aluminum generator that uses the Hall-Heroult process to produce aluminum from the alumina, a pump such as a flow pump or a pressure pump, a combustion engine that receives the hydrogen and produces steam, a condenser that receives the steam and produces recovered water, and a water filter that filters the recovered water. The hydrogen is produced when and where it is consumed by a consuming apparatus. The reaction chamber comprises an inlet for receiving aluminum, hydroxide or water. The aluminum, hydroxide or water is provided to the reaction chamber prior to the reaction chamber receiving the aluminum, hydroxide or water from the inlet. Two of the aluminum, hydroxide and water are mixed before received by the inlet. The hydroxide source and the water source are solution, which contains 74 grams of sodium hydroxide and 100 ml of water. The aluminum source and the hydroxide source are the mixture, which comprises a binder that keeps the aluminum and the hydroxide in a desired ratio. The binder prevents water from reacting with the aluminum and the hydroxide. The binder release mechanism comprises heat and water soluble solvent, and requires the heat to be at a temperature greater than the boiling point of water. The binder comprises an anti-caking agent, a flowing agent, a talcum powder, diatomaceous earth, a silicone-based binder, a thermo adhesive, a petroleum distillate, rosin, a lead-based binder, an indium-based binder or a wax. The solvent comprises an alcohol, a petroleum distillate, acetone, a chlorinated hydrocarbon, a detergent, an organic solvent, an acid, a cyclic hydrocarbon or a polycyclic hydrocarbon. The aluminum is in the form of paste, gel, pellet, powder, wire or rod. The heat exchange mechanism comprises an open vessel containing a heat exchange fluid, or a metal structure. The aluminum is added to the waste solution of the waste reservoir to produce hydrogen. The hydroxide source comprises the precipitator. The alumina generator receives heat produced by the reactant-limited chemical reaction. The water source comprises the alumina generator. The aluminum generator provides electricity generated from heat produced by the reactant-limited chemical reaction. The reactant-limited chemical reaction is controlled in accordance with the use of the hydrogen. The reactant-limited chemical reaction is performed using alkali metal, where the amount of produced heat corresponds to the alkali metal. The heat generated by the reactant-limited chemical reaction is provided to a heat pump that is used to cool an interior of a building, a body of water, a cabin of a vehicle, an interior of a tent, an interior of a temporary structure or an engine. An INDEPENDENT CLAIM is included for a method for generating hydrogen.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a hydrogen generator having a chemical reactor.
