Abstract: This invention relates generally to an article that includes a non-wetting surface having a dynamic contact angle of at least about 90°. The surface is patterned with macro- scale features configured to induce controlled asymmetry in a liquid film produced by impingement of a droplet onto the surface, thereby reducing time of contact between the droplet and the surface.

Abstract: The invention relates to a method for detecting icing and other loadings on blades of wind turbines. Advantageously, the method utilizes existing wind turbine actuators, for example pitch actuators, far excitation of blade vibrations. Vibration sensors on the blade such as strain sensors or accelerometers measure the blade vibrations excited in response to the actively excised vibrations. By comparing the measured response with previously obtained reference responses, it is possible to determine if blade icing is present.

Abstract: A hydro-pneumatic system generates power from wind energy transferred to a hydraulic flow, which in turn enables production of electricity by actuating a hydraulic motor/turbine. The wind hydro-generator works efficiently and at higher capacity utilizations at lower and higher wind speeds than conventional wind turbine technology. Conceptually, the invention represents a wind hydro-generator that uses a wind rotor to generate a torque, rather than to simply convert the wind power into a rotary motion and exploit the velocity. The torque is converted directly by a hydraulic generator into a water flow whose pressure is stabilized by a pressure vessel using compressed air to amortize the variances of the gusts of the wind. This stabilizes and steadies the power delivered by the water flow to the hydraulic motor over reasonable periods of time.
