Bladeless Aerogenerator (Harmonic Oscillation)

Here is my design for a Bladeless Aerogenerator that builds upon the Vortex Bladeless Concept. This aerogenerator has a 3.5m triangulated antenna tower core that suspends a 3m length of 10mm aircraft cable through the center. An ECU runs the stepper motor that controls the tension of the cable similar to tuning a guitar string. This center cable runs through a free floating magnetic oscillator core. The aircraft cable and oscillator core collect a large cross section of available wind power due to the 300mm diameter x 3.4m long fiberglass or carbon fiber outer tube. The wind is able to harmonically oscillate over the entire length of this outer housing due to the balance of this free floating core. In low wind conditions the tension can be reduced to gather as much of the available wind power as possible. As the wind speed increases the tension of the cable is adjusted to match the natural resonant frequency of the wind at that particular speed determined by an anemometer on the top of the mast. The vibrating electromagnetic field induces an alternating current in 5 copper coils. The AC current that the coils generate can travel long distances with minimal power drop. Only a small amount of power is pulled from the output to run all the DC components that synchronize the system to the winds harmonic frequency. This concept should be easy to scale down to a size that would fit in a wind tunnel for testing.
