Wind Power (v 4.0) learning with pivoting front wheels andOur fourth generation wind turbine kit! Wind is one of the most promising sources of clean, renewable energy available today. With this kit, you can assemble a realistic wind turbine complete with electric generator and adjustable rotor blades that are designed with complex aerodynamic curves to look and work like modern day wind turbine blades. Then, conduct experiments to optimize the turbines performance by adjusting the angle of the blades and
