Abstract

Vertical axis windmill turbine assemblies, as well as methods, systems and components related thereto. In one illustrative embodiment, a central shaft is supported by upper and lower bearings allowing it to rotate. Upper and lower support plates are disposed on the central shaft and support a plurality of vanes that extend therebetween. Each vane may have a closed leeward side formed from at least two planar members that join at a central ridge and an open windward side. Generators may be operatively connected to the central shaft at the lower end and the upper end. Multiple vertical axis assemblies may be disposed on a planar platform. Where multiple assemblies are present, they may be positioned to optimize production based on prevailing wind directions and may include windmill and turbine assemblies optimized for different wind conditions. In some systems, the assemblies may be disposed in a linear array.
