    I have to start with some negative points. This unit was first listed at a ridiculous 4200W, but later reduced to a claim of 500W. This is still overstated. The kinetic energy in the wind at the rated speed of 11 m/s is 521 watts, but the laws of physics (e.g. Betz law) limit this to 309 watts recoverable, even if we use an "ideal" machine. A more practical estimate would be 200W at 11 m/s. The global average wind speed is about 7.4 MPH (11.84 KPH), that is about 3.3 m/s. Power varies with the cube
