Wind turbines at Quinnipiac University draw attention to their quiet

From The New York Times: The wind turbines on the York Hill campus of Quinnipiac University in Hamden, Conn., are perhaps the first significant wind installation on an American college campus. The "wind garden" is free of propellers and their objectionable whoosh. Each of its 25 upright cylindrical turbines is encircled by a vertically aligned apparatus that spins slowly and in virtual silence.
