Abstract

The wind mill has conical shape, and is constructed from a vane ring resting on rollers (S) standing on brackets. The ring is supported at the central point (P). Vertical stringers meet at the apex of the cone, and the wind vane blades are located across the stringers at an angle to the base. The airflow (V) passes through the cone and catches the blades on the reverse side to help rotation.
