PROBLEM TO BE SOLVED: To provide a pumping machine and a system capable of performing hydraulic power generation anywhere by recirculating water without specifying an installation location. SOLUTION: An upper water tank and a lower water tank are provided in a power generation system and height difference between the water tanks is defined as water head, potential energy of water is used for power generation. The upper water tank, a hydraulic turbine and a generator, the lower water tank are arranged in an order. Water passing through the hydraulic turbine is guided to the lower water tank, and is pumped up to the upper water tank by the pumping machine connected to the lower part water tank. The pumping machine has a cylinder structure and pumps up water by applying Pascal's principle. Water pressure, air pressure, oil pressure, solid movement, magnetic force or the like is used as a method of generating driving force of a piston in the cylinder to drive the piston. Power generation can be sustained by repeating a process in which water in the cylinder is pumped up to the upper water tank and is recirculated. Pumping height can be adjusted by changing piston drive force and power generation quantity can be easily adjusted. The system can be introduced at any place where the upper water tank and the lower water tank can be installed without specifying a place. COPYRIGHT: (C)2007,JPO&INPIT
