Vertical Axis Wind Turbine
A vertical axis wind turbine is disclosed, including an axle and a plurality of blades circumferentially spaced about the axle and coupled to the axle. Each blade can include an outer surface and an inner surface, the outer surface and inner surface meeting at a leading edge and a trailing edge. Each blade can include a leading portion extending from the leading edge along the outer surface and the inner surface, the leading portion having, in longitudinal cross-section, an airfoil shape. Each blade can include at least one transverse channel located rearward of the leading portion. Each blade can include a trailing portion extending rearward from the channel to the trailing edge. Each channel can enhance wind turbine power output.
