Document Type and Number:
WIPO Patent Application WO/2019/125628
Kind Code:
This invention provides output gain by rotating a solid wheel from the center of mass as an input and connecting a lever to the edge of the same wheel at 180 degrees apart to each other. Each lever is connected at 180 degrees apart at the input rotating wheel with a common fulcrum located near the output side. This lever, acting as a mechanical lifting device, drives one side of output gain driven by the ratio of the length of lever to and from fulcrum between input and output while the other side is provided by another lever at 180 degrees apart. A unidirectional rotor converts the lever motion of up and down to a rotational motion. Weight of materials in a system is recycled back as an input to a hydraulic lever that generates hydraulic pressure driven by the movement of the system weight as it bounces off the surface.
