Vertical axis wind turbine airfoil

A vertical axis wind turbine airfoil, comprising:

• a leading edge;
• a trailing edge, wherein the distance between the leading edge and the trailing edge is defined as one;
• an upper curved surface extending from the leading edge to the trailing edge;
• a lower curved surface extending from the leading edge to the trailing edge;
• and
• a centerline running from the leading edge to the trailing edge, wherein the maximum distance between the centerline and the upper surface is a thickness defined as 0.5 and wherein the airfoil is shaped to have a thickness at specific distances from the leading edge to the trailing edge according to the following chart:
