Vertical Axis Wind Turbines

摘要

Abstract A vertical axis wind turbine (1) is described. The wind turbine (1) can include a top ring (84), a middle ring (82) and a lower ring (84), wherein a plurality of vertical airfoils (81) are disposed between the rings. For example, three vertical airfoils (81) can be attached between the upper ring and the middle ring. In addition, three more vertical airfoils (81) can be attached between the lower ring and the middle ring. When wind contacts the vertically arranged airfoils (81) the rings (84, 82) begin to spin. By connecting the rings (84, 82) to a center pole (105) which spins an alternator (90), electricity can be generated from wind. 1-2 200 r-300 400 ALTERNATOR ---- ONTRyN BATTERY
