Abstract: A metal air battery having multiple anode-cathode disc assemblies that include a first and second cathode disc flanking an anode disc. An actuator moves at least one cathode disc relative to the other cathode disc, and thereby facilitates the size of the anode-cathode gap. The anode disc has a hole that engages a power shaft to rotate the anode disc.

Abstract: A control system is described to improve all dynamic, multi-cell metal air batteries to ensure load requirements are met while optimizing battery performance according to a range of performance criteria. This control system can be augmented with Machine Learning to further improve both the effectiveness and efficiency of the battery system over time. A dynamic multi-cell metal air battery system design is disclosed to achieve continuous or intermittent high power, broadening the applicability of metal air batteries combined with electric motors to applications traditionally reserved for internal combustion engines.

Abstract: A method and system for improving the fuel economy and lowering the emissions of internal combustion engines by injecting predetermined amounts and ratios of on-board or locally generated hydrogen and oxygen to the engine's air intake and varying the gas addition volume and hydrogen/oxygen ratio as a function of the operating conditions, e.g., in line with the instant engine load.

Abstract: A rocket vehicle and engine including a manned suborbital rocket including a nose cone; a crew cabin operably connected to the nose cone; and a rocket engine employing the German A-4 (V-2) design. The rocket engine includes an injector; a combustion chamber operably connected to the injector; and a nozzle operably connected to the combustion chamber, the nozzle having an ablative liner. The injector, the combustion chamber, and the nozzle employ a German A-4 (V-2) rocket engine design.
