Japanese Breakthrough in Wind Turbine Design

While energy from wind turbines currently accounts for less than one percent of total power generated in Japan, the new breakthrough in design provides ample reason to ramp up production. Called the 'Windlens,' Yuji Ohya, a professor of renewable energy dynamics and applied mechanics, and his team at Kyushu University have created a series of turbines that could make the cost of wind power less than coal and nuclear energy. The two major concerning issues with traditional turbines have been their general inefficiency and intolerable noise. However, Kyushu's researchers found that attaching an inward curving ring around the perimeter of a turbine's blades increases the focus of airflow faster through the blade zones at two to three times the speed as before. An improvement in safety from covering the outer edges of the blades and a reduction of the dreaded noise pollution of older models is just a bonus.
