Centripetal force cannot accelerate a vehicle as once this centripetal force reaches a vehicles ‘net force resistance’, the resistance of a physical object to any change in velocity, the centripetal force becomes tangential. This Angular Momentum Engine centripetal force can only equal a vehicles ‘ ’ net force resistance, therefore acceleration is left to the exiting propulsion system, such as a series or parallel automotive hybrid systems, as an example. Centripetal forces are exponential, as its force is proportional to the square of the speed, while acceleration forces are linear giving this patent design an exponential edge over existing propulsion systems.

US11021854B2	Liquid desiccant vapor separation system An atmospheric moisture harvesting system, in which water vapor is separated from the air using a liquid desiccant subsystem.
