To solve a problem such as arguing a problem of CO2 reduction and radioactive pollution in a global scale, since the global warming and environmental problem recently gain prominent attention, though electric power is conventionally hydraulic, thermal and nuclear power generation and these impart cultural life to the Japanese people.

An artificial rapid stream and an artificial waterfall (6) are made in a corner of a river, and are formed as heavy blow water, energy is made by a water turbine (5), and a central part is fixed to a shaft (7), and is received by a high speed bearing (8). High speed power generation is performed by a generator (12) by increasing a rotating speed by connecting a pulley (9) and a generator side pulley (10) by three belts (11). Newly-made electric power is gathered and transmitted by a transformer station (14). When creation of not impairing a scene is made in a belt-like flow area of rivers, and several tens or several hundreds of power generation devices suited to uses are installed, electricity can be sent to a factory and many residents of an apartment house or the like of the area. When a two-stage power generation system is made for coping with failure such as power failure, a globally-friendly generator for permanently continuing power generation is provided.
