Abstract

Windmill comprising a number of propellers of different diameter coaxial to the power take-off shaft and connected to it by appropriate kinematics to create greater velocity ratio the smaller the diameter of the propeller and in general optimal transmission ratios and direction of motion depending on uses and environmental characteristics. <IMAGE>
