PicoTurbine's Savonius Model Wind Turbine Plus kit is a fully function miniature vertical windmill. At wind speeds of 12 mph it produces approximately 3.0V/50mA. The frame is built from high quality craft wood and coated with premium enamel to help protect it from the elements. The kit comes with 4 ceramic grade-five magnets and 4 (220)-turn copper coils. This hobbyist's kit walks users through every aspect of capturing and converting wind power into electricity. Users learn how to make S-foil wind blades that can (unlike horizontal wind blades) capture energy from any wind direction. They build step by step an alternator that will use magnetic induction to produce electrical current. The rotor distance is adjustable to the coil array, allowing users to witness magnetic strength principles. The wind turbine produces alternating current that can be displayed when connected to the bi-color LED. This special LED emits alternating red and green light when voltage switches from positive to
