t is disclosed herein a wind generator composed of four rotary blades (1,2,3,4), one vertically positioned rotary shaft (5), two independent horizontal axles (6,7), four ball bearings (8), and four stoppers 9. Under air pressure, the one blade acquires a transverse position, while the opposite one is setting lengthwise the airflow. The vertical shaft is brought into rotational motion due to the great difference of the aerodynamic resistance created between said blades. At the same time, beingin a neutral state, the remaining blades do not exhibit any resistance to the rotary motion of the vertical shaft 5. |
