||15031551||John Henry TURNER||John Henry TURNER|
A system for providing electrical power to a facility includes a generator configured to generate electrical power for the facility when a drive- shaft of the generator is rotated. A motor is configured to provide torque to rotate the generator drive-shaft and to be driven by a first power supply. A mechanical energy provider is configured to provide torque to the drive-shaft using mechanical energy generated from an intermittent local power source. The system is configured to defer to the mechanical energy provider to rotate the drive- shaft such that, when the intermittent local power source is active, less power is needed from the first power supply to power the motor than when the intermittent local power source is inactive.

||PCT/CN2015/000106||LI, Tao||LI, Tao|
An Archimedes' screw gravitational power system comprises an Archimedes' screw power wheel (3), a rotating shaft (2) and a supporting frame (1). Two ends of the rotating shaft (2) are arranged on the supporting frame (1) via bearings, and the Archimedes' screw power wheel (3) is fixedly sleeved on the rotating shaft via a hub (4). The Archimedes' screw power wheel (3) is a closed hollow communicating cylinder structure consisting of several identical Archimedes' screw members sequentially joined as rings, and a hollow cavity thereof is filled with a liquid. Curved lines in a cross-section of the Archimedes' screw member are two concentric Archimedes screw sectional lines reversed from the inside to the outside. In a process of rotation of the Archimedes' screw power wheel, a liquid surface height changes vertically with a rotation angle, converting potential energy into kinetic energy. The system does not depend on fossil fuels such as coal or petroleum and the like, has a low cost and does not contaminate the environment.

||13894606||KIMURA MITSUTERU||KIMURA MITSUTERU|
A wave activated electric power generating system is disclosed that is durable even if it is exposed to a rainstorm, extremely simple in structure and highly efficient in power generation. A motion transfer medium rendering the rotary part of an electric generator less liable to produce slipping and a rotation transform member adapted to rotate while fitting with the motion transfer medium in movement are also provided. The system includes a buoy floating on the sea or a lake where waves are high so as to move up and down with an undulation of the waves, and an underwater motion restrainer that is suspended underwater by water resistance (underwater suspension type), or alternatively submerged by its own weight on a floor of the sea or lake (bottom of water installation type), to lie substantially at a standstill. Vertical up and down movement of the buoy relative to the underwater motion restrainer is converted and transferred by the motion transfer medium in the form of an elongate rope vertically moving under the weight of a weight element 7 to operate the rotary electric generator securely connected to the buoy. The system is provided with a guide means which ensures that the rotation transform member for the electric generator and the motion transfer medium may not come off each other even under raging waves. So that they may not slip from each other, the motion transfer medium and the rotation transform member are each formed thereon periodically with a corrugation.
