PROBLEM TO BE SOLVED: To solve a problem that there is a limit to hydraulic power as a power source of today, that thermal power casts a serious shadow over global warming, air pollution or the like along with exhaustion of resources, and that nuclear power presents safety problems. SOLUTION: In conjunction between a ventilation fan and the so-called air channel, wind pressure which increases in proportion to the second power of wind speed is made a power source of a rotator constituted by blades. Then a plurality of rotation-promoting mechanisms are added to the rotator, and the difference between input and output is increased. As a rotation-promoting mechanism, such additions are made as a nose-lowering flap, a rotation initial condition, an inertial moment, operation of a fluid "wind" which makes the functioning of the blades more effective, eyes by likening the fluid "wind" to a whirl or the like. Since the rotation-promoting mechanisms have a structure of rotating a shaft core from the outer periphery, the operations can be performed with relative ease. COPYRIGHT: (C)2008,JPO&INPIT
