Abstract
An improved sail restraint for Migler's vertical axis wind turbine in which excessive wind speed automatically causes the sails to be feathered, protecting them from wind damage, and, when the wind speed is reduced to an allowable level, the improved sail restraint automatically allows the sails to be reset to their nonfeathered, working position.
