New fallout from Fukushima, except this is a good thing. Wind lenses. Japan’s reconsideration of its use of nuclear power has given a boost to a technology developed at Kyushu University. Their wind lens is a ring added to a turbine that creates a pocket of low pressure in front resulting in a pressure differential that concentrates wind flow and increases the speed and power output. Prototypes exist on campus in Fukuoka. Take a look at this video to see a real-time test and the really cool design concept for floating these turbines in the ocean.
I discovered there are other wind power enhancement systems with videos on YouTube, although some of them do harm to their cause with the quality of their video. (Thumping dance music anyone?) This one came across OK:
