A wind turbine is provided to overcome the low conversion rates of existing thermal wind turbines, which are unable to meet the growing demand for power. A wind turbine tower (7) is provided with a shaft (3) that extends vertically from the bottom or the middle of the tower to the top of the tower. The top end of the shaft is connected to the rotation shaft of a generator (2). A flywheel (4) is provided at the bottom of the shaft (3). Air inlets (8) are provided about the tower wall at the bottom of the tower and are oriented upward. A screw flight (31) is provided about the shaft, spiraling upward from the bottom to the top thereof. The wind turbine reduces loss of wind power, makes full use of wind energy, and achieves wind-to-power conversion rates of at least 85%. |
