Wind farm technology goes sonic

June 5, 2007 The pressing need for viable alternative energy sources that do more than just supplement coal fired power-stations is driving advances in the development of wind energy. One major hurdle in establishing successful wind farms is the difficulty in attaining accurate site evaluation data and it is this problem that the Triton Sonic Wind Profiler seeks to address. Designed to measure wind-speed at heights of up to 200m without the need for erecting costly and less effective masts, the wind profiler utilizes a technique known as Sodar (sound detection and ranging) that measures sound wave echoes in the atmosphere in a similar way to Sonar detection used by submarines underwater.
