Silent flights: How owls could help make wind turbines and planes quieter
A newly designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
Hydroelectricity gets an ecological makeover in Norvay
Norway, a country that generates more than 80{f24b02adee2102ff0c5f5079c50862fc8ba5fa53f8615b567037555463da2377} of its electricity from hydropower, has added to its renewable repertoire in the guise of a beautifully Kebony-clad 30GWh plant. The plant is situated deep within the mountains of Helgeland, a hiker’s paradise just below the Arctic Circle. The region is known for its unique coastline and spectacular mountain formations and the architects wanted the plant’s design to be inspired by and reflect the landscape, whilst also functioning as an attraction for hikers in the back country wilderness. The Øvre Forsland power station has been designed to educate hikers about power production by allowing visitors to experience the production of hydraulic electricity at various points throughout the process. From the nearby bridge, the powerful water flow that drives …
