A wind turbine for converting wind energy to useable energy having a plurality of overlapping sail members. The sail members extend radially outward from a vertically disposed shaft in three columns positioned equidistantly around the shaft. The overlapping sail members hang downwardly in a naturally biased, vertical orientation so as to block rotational movement of each other in one direction. This configuration allows the wind to engage with the sail members on one side of the shaft to rotate the shaft, and blow past the sail members on the other side of the shaft. Rotation of the cylinder is thus achieved while wind resistance is greatly minimized, regardless of the wind direction. A generator can be rotatably intercoupled with the cylinder to thereby convert the kinetic energy of rotation to useable energy. Each sail member is preferably positioned such that a gap resides between the sail member and the shaft, the gap being at least as wide as the sail member. Each sail member includes a rigid frame having a geometric centroid and a center of mass which resides above the geometric centroid when the frame is hanging downwardly.
