Windmill used to generate electrical energy and located in the central reservation of a motorway, has propellers mounted on vertically extending spaced shafts and driving generators

摘要

The propeller has blades, the length of which in the direction of the shaft is greater than the width. The generator is coupled with more than one shaft, on each of which a propeller is fitted. The shafts have a mutual intermediate spacing and are placed in a line, fulfilling a separating function. The mills are positioned one behind the other and are placed in the central reservation on a protective rail of a motorway.
