Our project is a mini windmill that uses wind energy to generate electricity. This process is achieved by creating a propeller and connecting it to a motor. This motor lies on a free rotating base that rotates above a stand (truss) that supports the whole mill. Rotating the base to face the direction of the wind is achieved by connecting a back rudder to the base. • How does it work? Electric energy generation starts when the wind rotates the propeller
