The double pendulum in dynamic motion generates chaotic movement. The current invention integrates two double pendulums with electronic controllers to control the chaotic movement, and a transmission set to use the controlled motion to spin a shaft. The electronic controller provides impulse to each double pendulum and controls the frequency of the oscillations to generate a constant swinging bi-directional motion of the double pendulums. The upper ends of the double pendulums are coupled to a reciprocating transmission set that transforms the swinging bi-directional motion of each double pendulum into a unidirectional spinning motion, transmitted to a horizontal shaft, generating a constant speed as output.

A pump jack controller is provided that can harness the potential energy generated during the operation of one pump jack amongst a plurality of pump jacks located at a well site and convert that potential energy into electrical energy that can be used to provide electrical power generated by the pump jack to power the other pump jacks located at the well site.

The present disclosure relates to a swing bearing and a wearable device. The swing bearing includes an inner ring, an outer ring, and a plurality of rolling elements, a plurality of first grooves arranged at intervals along a circumferential direction being formed on an outer circumferential surface of the inner ring, a plurality of second grooves arranged at intervals along a circumferential direction being formed on an inner circumferential surface of the outer ring, each rolling element being disposed between the corresponding first groove and the second groove, and the rolling element, the first groove, and the second groove being configured to restrict relative rotational movement between the inner ring and the outer ring and allow the inner ring and the outer ring to produce shaft axis deflection movement.

An energy storage system includes a crane and a plurality of blocks, where the crane is operable to move blocks from a lower elevation to a higher elevation (via stacking of the blocks) to store electrical energy as potential energy of the blocks, and then operable to move blocks from a higher elevation to a lower elevation (via unstacking of the blocks) to generate electricity based on the kinetic energy of the block when lowered (e.g., by gravity). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the power grid.

This invention is a mechanic machine that works by gravity using vibration. It consists of a hanged Pendulum in the middle, above which two gears are fixed which are the movement generator for all gears in both sides in order to generate clean, consistent and free power. In bottom of Pendulum, attached a dissonant magnet and in bottom of machine there is another dissonant magnet to secure consistent movement of Pendulum continuously, in addition to two iron curved brackets, each is almost quarter circle carrying all parts of this invention, vibrating with Pendulum movement whose bottom is heavier than its head, in addition to some diversified gears and mechanical fixations to increase speed, multiplate movement and control movement in single direction. This machine could be minimized and maximized as needed, and we can replace magnet with a small hydraulic piston in a side. There are 2 dynamos for power generation in both sides. Robot can be employed to operate this machine. Refer to FIG. 2
