Cylindrical wings with longitudinal grooves, streamwise grooves and spiral fins are used to clarify the performance of the magnus windmill. Windmill number of revolutions was measured using a wind tunnel at wind speed of 4~20 m/s and a cylinder rotation at 400~1600 rpm. As a result, it was revealed that a spiral fin has a windmill rotation with the lowest wind velocity and a longitudinal groove cylinder has a highest rotation number of windmill.
