Screwy-looking wind turbine makes little noise and a big claim
• http://www.gizmag.com, By Ben CoxworthThe 75-kg (165-lb) 1.5-meter (5-ft)-wide Liam obviously doesn't look much like a typical turbine. It draws on the form of the nautilus shell, and the screw pump invented by ancient Greek mathematician Archimedes of Syracuse.
That form factor reportedly results in minimal mechanical resistance, allowing it to spin very freely and to operate quietly – blade noise is one of the common complaints regarding rooftop wind turbines. Additionally, the design is claimed to keep it always pointing into the wind for maximum yield.
