Abstract
A wind turbine is provided which consists of novel vanes horizontally oriented about a rotating hub connected to a vertical shaft. The vanes are free to pivot about two horizontal hinges such that two vanes connected to each other open when wind force is applied, and close when there is little or no wind force such that there is a minimal amount of resistance to the travel of the vanes when the vanes are against the wind.
