Abstract
The present device is a vertically oriented wind turbine blade having a rectangular simple curvilinear shaped blade, which includes a top edge, a bottom edge, an outer edge, an inner edge, an inner surface and an outer surface. The blade is curved using a series of bent section to approximate as airfoil shape from the inner edge to the outer edge (relative to the turbine center or hub).
Claims1
An airfoil for use as in a wind turbine comprising:
- a rectangular blade shaped for a vertical axis wind turbine, the blade comprising one or more sheets of material including a top edge, a bottom edge, an outer edge, an inner edge, an inner surface and an outer surface wherein the blade comprises at least three bends extending from the top edge to the bottom edge so that the bent sheet of material approximates an airfoil shape without any internal structure.
