Abstract: As rotational mechanical devices accelerate or decelerate, they have an opposite reaction against their housing and/or their surroundings in fact to move the earth. This reaction represents wasted energy that is lost to the system. The invention comprises the use of equal and opposite force from an energy source gravity via activated spring, cable, or counterweight applied fresh as acceleration begins or lift and release from opposite or adjacent sides to reset. These methods can conserve as much as three-fourths of the applied energy for motors, machines, and other motion-related applications.

Abstract: As rotational mechanical devices accelerate or decelerate, they generate torque against their housing and/or their surroundings. This torque represents wasted energy that is lost to the system. The invention comprises the use of equal and opposite force from an energy source such as a spring or counterweight to counteract to the torque generating forces in the mechanical device.

Abstract: Devices herein described utilize vehicles that are propelled, braked, and steered by means of a process called Inertial Propulsion Plus. This consists of a "power phase" to extend the weight(s) from the vehicle, alternated with a "null phase" to cancel out the return phase or stroke reactions. This process is made workable by selectively applying a pure external force derived from the pathway and opposing the movement of the weight(s) on the power phase. For non-travel-related applications, the inherent displacement can be harnessed by a treadmill or other ways for a power source to increase available power and reduce pollution.
