You might have read about innovative UK consultancy XCO2's innovative quiet revolution urban turbines. Well, they have another trick up their sleeve in the form of their ground-breaking display turbines.
These turbines rely on the theory of persistence of vision – our brains ability to fuse many fast, static, images into a single moving image.
The theory is simple. The wind turbine blade has embedded within an array of light-emitting elements – high powered L.E.D's for example. These are coupled to an embedded processor, which controls these L.E.D's. For multi-coloured displays, the outputs of a red, green and blue L.E.D can be fused by the eye into a single coherent image.
When we finally start to invite wind turbines into the city, they might carry advertisements and information as we've never seen them before.
More after the jump.
