Abstract
A vertical axis wind turbine with improved safety, production efficiency and greater functional wind speed range. A vertical axis wind turbine comprises turbine blades having geometric characteristics of a “yin yang” symbol when viewed from the top down. The turbine blades are configured to form a scoop portion for catching wind. The surface area of the scoop portion may be dynamically configured to accommodate power production in higher wind speed ranges by dynamically furling the blades to reduce the surface area of the scoop portion as RPM begins to exceed a safe limit. First and second permanent magnet rotor arrays are dynamically positioned above and below an array of stator coils to maximize power generation.
