NOVELTY - The engine for converting hydrogen into mechanical movement, comprises a sodium hydroxide reservoir (1), an aluminum powder reservoir (2), a water reservoir (3), a carburetor with an additional air inlet, an accumulator (4) for electrical pumping of the sodium hydroxide, the aluminum powder and the water, and supplying of an ignition system, a control and operation system, and a propulsion system. The ignition system (12) produces the hydrogen combustion. The control and operation system allows to control the speed of the engine.    USE - Useful for converting hydrogen into mechanical movement.    ADVANTAGE - The engine does not affect the environment during the conversion of hydrogen into mechanical movement.    DETAILED DESCRIPTION - The engine for converting hydrogen into mechanical movement, comprises a sodium hydroxide reservoir (1), an aluminum powder reservoir (2), a water reservoir (3), a carburetor with an additional air inlet, an accumulator (4) for electrical pumping of the sodium hydroxide, the aluminum powder and the water, and supplying of an ignition system, a control and operation system, and a propulsion system. The ignition system (12) produces the hydrogen combustion. The control and operation system allows to control the speed of the engine. A combustion chamber transforms the hydrogen combustion in mechanical movement. The carburetor is used for contacting the sodium hydroxide, the aluminum and the water. The combustion chamber is supplied with the hydrogen, which is produced in the carburetor. The control and operation system regulate the sodium hydroxide, the aluminum and the water in the carburetor, and determine the combustion speed and the engine speed. The combustion chamber generates the mechanical movement from the hydrogen combustion, which is produced by chemical reaction of the sodium hydroxide, the aluminum and the water.    DESCRIPTION OF DRAWING(S) - The diagram shows an engine for converting hydrogen into mechanical movement:    Sodium hydroxide reservoir; (1)    Aluminum powder reservoir; (2)    Water reservoir; (3)    Accumulator; (4)    Ignition system.
