A wind power generator comprises a shaft operatively mounted in a support frame for rotation about a substantially vertical axis. A wing arm is fixedly mounted on the shaft and extends radially outward therefrom. Finally, a windtrap assembly is disposed proximal an outer end of the wing arm. The windtrap assembly includes respective upper and lower windtrap panels pivotably connected to the wing arm. The upper and lower windtrap panels are capable of folding together to cooperatively assume a low-drag configuration when the windtrap assembly is moving in an up-wind direction, and further capable of opening away from each other to cooperatively assume a high-drag configuration when the windtrap assembly is moving in a down-wind direction.
