The Yokohama Renewable Energy International Exhibition 2010 revealed some visually spectacular new designs for wind turbine technology. The Wind Lens has the potential to triple the amount of electricity produced by offshore turbines according to experiments. Kyushu University professor Yuji Ohya spoke of the merits of the 112-meter diameter structures being able to increase energy output “two or three fold”, as well as being about to reduce the dreaded noise pollution so often associated with wind turbines, and improve safety too.
Ohya’s idea is to create a series of wind turbines which focus the wind’s power, rather than using it directly. A series of them could thus turn a gentle breeze into a massive gust, easily able to power a turbine generator sitting behind a series of these contraptions.
