Posted Mon Jan 12 2009: from New Scientist:


	Patent: Tree-hugging wind turbine http://apocadocs.com/s.pl?1231782624 Sridhar Condoor at Saint Louis University in Missouri has designed a hollow, cylindrical wind turbine that has no central hub. Its tube-like form means the device could be placed around a pre-existing feature such as a chimney stack, cellphone mast or even a tree trunk. The outside of the turbine is a cylinder that is incised with inlets to catch the wind from any direction and toothed on the inside to drive a gear that powers a generator. A cylindrical frame within allows the main cylinder to rotate freely and can be mounted around another object -- either vertically or horizontally. That makes it possible to install without needing clear space, and could even provide a way to hide ugly features, the patent says.
