Yale Environment 360: A new type of coating for wind turbines inspired by the shape of owl wings may dramatically cut noise associated with onshore wind farms, according to research from the University of Cambridge. The scientists found that an owl's flight feathers have a microscopic down-like covering and numerous other intricate design details that smooth the passage of air over the wing, scattering sound as the owl flies. To replicate the structure, the researchers looked at designing a covering that would scatter...
