Harburg Rudolph W Rudy Harburg Rudy W. Harburg Rudolph W. Harburg Self-regulation pinwheel kite tail US 5183224 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. Type: Grant Filed: May 14, 1990 Issued: February 2, 1993 Inventor: Rudy W. Harburg ========================================== Coaxial multi-turbine generator US 5040948 Also as: WO 1991014868 A1 Abstract: Turbines are suspended coaxially between a hub structure and a pivot. The hub acts to stabilize the coaxial turbine system and it acts as the power take off. The pivot acts to stabilize the other end of the coaxial turbine system. A coaxial assembly of unique flexible turbines convert wind energy into rotational mechanical energy. Driver lines attached to the extremities of the turbines transmit this energy to the extremities of the hub structure. The hub imparts torque to a drive shaft at its center thorough a moment arm and the drive shaft supplies power to a useful application, such as generating electricity. The coaxial turbine system is suspended from tower to tower between existing power transmission lines. Electricity generated by this system is fed directly into the existing power distribution system. This coaxial generator system utilizes a variety of turbine configurations and can be suspended in the wind in a number of ways.
