Biggest Installation of Silent Urban-Styled Wind Turbines [View All]

[n2doc]

Wind may be picking up faster than any other energy source, but harnessing its power is largely left to remote wind farms that not everyone is crazy about. Keen to see the wind change in the way wind power is perceived on the street, Quietrevolution (QR) has done a makeover on the design of wind turbines, so they’ll look, sound, and work better in urban environments. No storms kicked up over them spoiling the view. No waking the neighbours with that ghastly noise. No worries getting the best out of wind in built-up areas.

Thanks to the aerodynamics of its vertical-axis wind turbine (VAWT) design, Quietrevolution has trademarked that most valuable of commodities in a world dominated by din: near silence. According to their website, those elegant S-shaped rotor blades shed noise and minimise vibration. Compare your typical horizontal-axis wind turbines (HAWTs), which sometimes hit the headlines - denied planning permission due to local opposition.

If the QR turbines are to brighten not be a blight on the urban landscape, its display turbines may have some say on the matter. Though still a product in in its early stages of development, the idea is that as the blades revolve, attached LEDs will light up in sequence, creating a screen that depicts colourful and moving images mid-air. Nifty, no? Well even if advertising here proves less illuminating to onlookers, people should at least be enlightened by displayed messages on climate change, or the turbines spinning as works of art in themselves.
Street cred from neat LEDs? Light Emitting Diodes to create dazzling displays
