An electric generating precipitation collection system comprising a collection tank, a plurality of pipes, a plurality of valves, a piston assembly, and an outlet. The system is configured to collect a liquid, direct the liquid through the pipes and valves to pressurize the liquid with the piston assembly, and eject the pressurized liquid at the outlet. The plurality of pipes and valves are arranged relative to the piston assembly so that a piston can pressurize the liquid in the pipe connected to the outlet. The system may further comprise a generator that converts the force of the pressurized liquid from the outlet into electricity. Further, a collection basin may be included in the system to collect liquid after passing through the generator.

A water pumping system used for lifting liquids in vertical or near vertical conduits or pipes to a higher elevation at a reduced energy cost. Also, the water pumping system can be used to circulate water between upper and lower elevations to generate hydropower energy at a lower energy cost. The water pumping system includes a water pump, air blowers, an air supply chamber, a lift conduit, a return conduit, a flotation device separation chamber, a plurality of floatation devices, one or more flotation device pushers, a dehydration unit, and two water storage tanks. The lift conduit and return conduit creating a continuous loop in which the flotation devices can circulate and act as a piston in the lifting conduit to elevate the water to higher elevations with reduced energy. The floatation devices include spacer rings and spacer rods. The floatation devices are inserted inside the lift conduit and the return conduit.

Power can be efficiently generated in accordance with the amount of water in a channel by including: a first headrace channel positioned on an upstream side; a second headrace channel positioned on a downstream side; a water wheel on a most downstream side of the first headrace channel and the second headrace channel, the water wheel having a rotation shaft in a direction orthogonally intersecting with a water flow; a lateral movement apparatus that enables the second headrace channel to be moved in an upstream direction or a downstream direction; and a vertical movement apparatus that enables the water wheel to be moved in a vertical direction.

The disclosed hydroelectric power generation system includes a waterwheel rotated by falling water having multiple curved portions. Multiple circular members each having a cover are loaded in a corresponding one of the multiple curved portions, elevated with the cover in an open position to empty the circular member, filled with water upon reaching a top dead point thereof, and allowed to fall freely with the cover in a closed position. The cover of the circular members are automatically opened and closed. A track extends downwardly from a point at which the curved portion of the waterwheel is turned into a downwardly inclined position. The track guides the circular member to move by gravity along the track. A feed track allows the circular members to be supplied back to respective curved portions during rotation of the waterwheel. An output shaft of a gear train drives a generator.

A floating electrical power generator having a three-dimensional (3D) flow passageway configured for increasing the water flow on the paddle wheel to increase the power output.

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.
