PROBLEM TO BE SOLVED: To provide a Francis turbine power station, a Pelton turbine power station, and a bevel gear propeller power station in a power generation mother ship by mooring a large-sized power generation mother ship at a right angle to the current by an anchor by utilizing the current of a Kuroshio flowing along the Japanese Islands. SOLUTION: An opening part of a large-sized power generation mother ship is provided with a Kuroshio inflow port, just under the Kuroshio finishing the power generation for a Francis turbine power station 12, a distributing steel pipe is projected by 11 meters, and there is provided a Francis power station for pulling with suction force with 3 normal atmosphere by the tide of the Kuroshio in the steel pipe. Inboard both sides are provided with a Pelton turbine, there is provided a worm gear fitted with a power station 3, which is adapted to generate power by rotating a worm 7, and further there is provided a bevel gear power station which is adapted to rotate a bevel gear fitted with a power station by the rotating force of the propeller 4.
