This 4ft diameter involute spiral-vaned vertical axis wind turbine (VAWT) weighs less than 30 lb for the entire turbine above the base, including rotating 20ft mast, tension wires and guy cables! Wind goes inside the turbine, pushing and lifting on the non-constricting spiral vanes directing it through the entire 3-dimensional contours of the turbine. The many advantages of this design can be learned on my webpage, www.fundamentalform.com/html/involute_wind_turbine.html

The visual pulsing is due entirely to the three-fold balance of the vanes. We are used to 4-fold symetry. Yes, I am building an alternator to hook? up to a battery and LEDs on the turbine ~ should look cool!
