(1) Gravity assisted mechanical machine that uses a combination of stored mechanical energy plus the downward force of gravity, regulated by a motor and a sophisticated switch powered by a rechargeable battery. The mechanical switch is also assisted by a lever so the motor is more efficient in the use of the battery power. (2) Older types of fuel powered mechanical machines cause greater pollution and need an enormous amount of support to continue operating daily. (3) The gravity assisted mechanical machine can be used without air and operates longer and more efficiently and is less noisy and has no emissions to cause pollution. It will not heat up like a conventional mechanical machine only when attached to a generator for electrical energy. It will work without the need for the enormous weight of fuel to produce electrical energy. It can be used to power some electrical generators, example wind mill generators, for all uses of electrical energy.

A rotation device includes an output shaft, at least one rotatable rotary plate member arranged so that its rotation axis and the output shaft are coaxial, at least one weight member fixed to the rotary plate member, for biasing position of the center of gravity from the rotation axis of the rotary plate member, and at least one clutch mechanism arranged between the rotary plate member and the output shaft, for separating the rotary plate member and the output shaft with each other at a predetermined rotation angle. The clutch mechanism connects the rotary plate member with the output shaft when the center of gravity of the weight member descends, and separates the rotary plate member from the output shaft when the center of gravity of the weight member rises.

An energy storage system comprises a cable (13) and a mass 20 suspended from the cable (13) in a shaft (12). The cable (13) is attached to a winch 11 by which the mass may be raised in the shaft (12) to store potential energy, and the mass is lowerable in the shaft (12) to release the potential energy. The mass comprises at least two sections clamped together around the cable (13). More particularly, the system comprising a plurality of cables (13) and a plurality of multi-section masses each suspended in the shaft (12) by a respective cable (13), the masses being raised and lowered in synchronism in the shaft (12). The multi-section masses fit together side-by-side in the shaft (12) to form an overall cylindrical mass body, the multi-section masses each forming a quadrant of the cylindrical mass body.

A new propulsion mechanism is disclosed that comprises of at least two arms located opposite to each other, each arm has two axes of rotation at its two ends, and a weight that is slidable on each arm. Corresponding axes of rotation of each arm attach to and detach from each other in a cyclic manner by a set of retaining chassis. The connection of the opposing arms supports their position and stabilizes the motion of the system. Each arm rotates around its own axes and carries its weight according to the pattern and time table shown in (FIG. 1) (FIG. 2). The result of this process creates a force in a specific direction. When the ends of the arms are connected, they will act as a support for a structure that is attached to them. The structure moves in the appropriate direction.

A power transmission assembly includes a base, a rotating frame rotatably coupled to the base and configured to rotate about an axis, an output shaft coupled to the rotating frame, a weight selectively repositionable relative to the rotating frame, and a weight actuator configured to reposition the weight relative to the rotating frame to move the weight from a subtraction position located at a first height to an addition position located at a second height. The second height is greater than the first height such that a gravitational force on the weight drives the rotating frame to rotate about the axis and drive the output shaft.

A highly efficient, utility scale energy storage system employs large masses transported uphill to store energy and downhill to release energy. An electric powered cable winch or chain drive shuttles the masses between two storage yards of different elevations separated by a steep incline on rail vehicles supported by track and operated by an automated control system.
