<P>PROBLEM TO BE SOLVED: To rotate a plurality of vertical shaft wind turbines in synchronization with each other to drive one power generator by the plurality of vertical shaft wind turbines, to efficiently drive the power generator. <P>SOLUTION: A plurality of vertical type drag wind turbines with two blades are connected with gears to drive a single power generator. At this time, the neighboring wind turbines are disposed so that planes (reference planes) passing an axis of the wind turbine and in parallel to wind receiving faces of blades are different from each other to have a fixed angle. In particular, when the difference is set at 90 degrees, "an increased number of wind turbines" can be arranged in the same installation space, by applying elliptic gears. <P>COPYRIGHT: (C)2011,JPO&INPIT |
