ABSTRACT:
A vertical axis wind turbine having a plurality of blades spaced from a rotatable around a rotor shaft vertical to the ground. The plurality of blades are arranged in a helical pattern about the rotor shaft. Each blade is flexible to move in response to wind and has a top, bottom, leading edge, and trailing edge wherein the leading edge is in the shape of an airfoil. A hub having a plurality of blade attachment rods radially extending from the rotor wherein in one blade is secured to one of the attachment arms. The hub has a plurality of attachment rods radially extending from the rotor wherein one blade is secured to one of the attachment rods near the center and wherein the top of each blade is closer to the rotor than the bottom of each blade.
