ABSTRACT:
A wind turbine journaled on a support for rotation about a substantially vertically positioned axis and employing trough-like vanes spacedly positioned around the axis and extending longitudinally thereof. A windshield is rotatively mounted on the support for surrounding and shielding at least a part of the vanes, which windshield is adjustively positioned relative to the wind to compensate for high wind speeds and resulting wind damage to the turbine.
