Abstract
A wind turbine has a visual envelope suggestive of a flame. The turbine has a rotor adapted to rotate about an axis of rotation that is perpendicular to a direction of a prevailing wind. The visual envelope is curvilinear, generally wider toward the root end, and narrower near the tip. A power take off device converts rotation of the rotor into a useful and preferably transmissible form of energy.
