Apparatus for harvesting power from the wind, mounted on a vertical support or pole, has two linear “power harvesting devices” arranged in V-shaped configuration with the apex of the “V” mounted for rotation in a horizontal plane about the vertical support. The two power harvesting devices move under the influence of incoming wind to orient themselves such that the apex of its “V”-shape structure always faces the incoming wind. The power harvesting devices are each provided with blades attached for movement with a linear endless drive conveyor. With the apex of the “V” facing the wind, the blades are oriented to intercept this wind and to cause movement of the conveyor drive to which they are attached.
