Abstract: The invention is directed to a wind turbine normally located in a vertical position in operation to provide a propulsion energy force. In general, the wind turbine consists of a central rotor unit having a plurality of spaced, longitudinally extending scoop-like collector blades joined together so that no air can pass through them, to rotate a central power take off shaft when engaged by air currents. The air is directed to the rotor blades by straightly extending vertical air guide panels which intermittently surround the rotor unit and direct air currents to the rotor unit for rotation by the wind. The air guide panels are closed at the top and bottom by horizontally extending guide panels which are canted in complementary directions. The upper panel is tilted downwardly as it progresses inwardly and the lower panel is tilted upwardly on its inward extent to thereby increase the velocity and pressure of the wind as it is directed to the rotor unit.
