ABSTRACT:
A swivel on a string is attached to the windward face of a pinwheel turbine. The other end of the string is attached to the aft portion of a kite thus creating a kite tail. Wind against its veins and leeward parts stabilize the pinwheel's orientation and cause it to spin. The pinwheel is light but tends to produce drag proportional to the velocity of the wind, thereby, stabilizing the kite in both low winds and high winds. A multiplicity of pinwheels can be attached in series on one kite tail, and one or more such kite tails can be attached to a kite to provide directional stability. This self-regulating tail can be used to help keep a kite airborne in an extremely wide range of wind speeds.
