Doug Selsam's turbine ideas are not just blowing in the wind; they are transforming the wind into power-generating machines. At a cost of $250,000 to develop, the 25-rotor turbine 'Sky Serpent' is said to produce three kilowatts (3000 watts) of power. The Sky Serpent is still in the concept stage, but Selsam has already sold over 20 home-built, 2,000-watt dual-rotor turbines. Some of the multi-rotor wind catcher models are moored offshore and held elevated high in the air by a blimp.
