This unofficial Lego Education SPIKE Prime eBook presents the building instructions (using a single SPIKE kit) and the code of a Wind Turbine.  The model has 2 versions. The first one uses the motor and changes the rotation speed of the blades according to the ultrasonic values. The second one does not have a motor and the rotation speed of the turbine is controlled by hand or wind. The code provided in the second case creates a graph that represents the rotation speed in the timeline.
