Abstract: A system and method for efficient wind power generation is provided. The system includes a shaft that rotates around a vertical axis, a plurality of blades, and a plurality of arms that couple the blades to the shaft. The blades are configured to have a rounded, symmetrical design which minimizes the effects of lift. The blades are also configured to include a notched portion for capturing wind and using it to propel the blades. The blades may also be configured to include winglets, which reduce vortex shedding, drag, and noise, and could also reduce friction on the bearings caused by gravity.
