Abstract
Flag-type wind and/or water power generation features are described. Fluid-filled embodiments are described. The fluid may be employed for pumping effect and/or dynamic physical property change. Leading-edge and trailing-edge mounted flag architectures are described with various applications including flapping flag arrays and Vertical Axis Wind Turbines (VAWTs).
