Wind Power Kit, Gigo
Build 2 large wind turbines, which are almost 1 meter high! Then use the energy generated by the wind turbine to switch on on a diode or to recharge a battery. Study what the difference in the design of the wings make to the wind turbine.
Then use the motor to build 6 other models, all of which can move.
The guide contains detailed pictures describing how the models are assembled. In addition, the guide (in English) contains explanations of concept and operation, so that you can also gain a greater understanding of the principles of wind turbines.
The set contains 133 parts.
