摘要： Systems and methods related to floating powerhouse for hydropower turbine systems are presented. A turbine system may be coupled to floating powerhouse that can include a floating platform. A pressurized water delivery system can be coupled to the floating powerhouse and can accommodate vertical and/or horizontal movement of the floating power house. The pressurized water delivery system can include a segmented penstock coupling the turbine to an intake, and individual segments of the penstock can be free to rotate about a substantially horizontal axis, such that in response to variations in a tailwater height, the floating platform rising and falling does not disrupt fluid flow from a fluid source.

摘要： A flowing water hydroelectric generator is consisted of a motor attached by power cord, an overdrive gear set assembled on the motor's axial and couple fixed axles including a sun gear, several planet gears and a ring gear having a gear hole, a shaft able to be inserted through the gear hole, a housing installed on the motor able to block and seal the overdrive gear set on the motor and an impeller connected to the shaft. The generator can produce more power because of the motor's rotating speed-up driven by the overdrive gear set turned by the shaft spun by the impeller swiveled by flowing water and has a variety of installing combinations and easily be installed or removed. The best power generation efficiency can be achieved due to the generator's prolonged service life, small volume, great capacity and good transmission.

摘要： A generator device for generating an induced electrical power from the movement of a fluid stream. The generator device can include a circumferential casing that houses a stator, a power storage system and a power management system that receives the induced electrical power, and a propeller-rotor assembly located in the central opening of the casing and rotatably coupled to the casing. The propeller-rotor assembly has two or more propeller blades with distal ends opposite the axis of the propeller-rotor assembly to which magnets are attached. The device can also have a tether assembly for anchoring the generator device in a moving fluid stream and positioning the generator device so that the movement of fluid stream through the generator device causes the propeller-rotor assembly to rotate and, thereby, through interaction with the stator, to generate the induced electrical power. The generator device can be portable and easily deployed by a single user.

摘要： A system for storing energy includes a body and a shaft having walls defining an internal volume for containing a fluid, a seal member disposed between the body and the walls of the shaft, and a fluid passage in fluid communication with the shaft. The body is disposed within the internal volume of the shaft for movement with gravity from a first elevation position to a second elevation position within the internal volume of the shaft. The seal member divides the internal volume into a first portion located below the body and a second portion located above the body. The fluid passage communicates fluid with the first portion of the interior volume of the shaft. The system further includes a pump/turbine operatively coupled with the fluid passage to drive a motor/generator to generate electricity upon movement of the body from the first elevation position to the second elevation position.

摘要： The present disclosure first uses a pumping device to retrieve water using an internal power source from a water source. Then, in accordance with a wind parameter and a solar parameter, wind-powered and solar-powered pumping devices are selectively engaged to replace the pumping device. The water is stored in the water storage device in a higher place. As the water runs through an inlet pipe, it is pressurized to drive a first hydraulic generation device. Then the water's potential energy is used to drive a second hydraulic generation device as the water is recycled to the water source. The produced electricity is delivered to the pumping device and, if any remaining, then to a light device for illumination.
