Laser Guidance Adds Power to Wind Turbines

From Wired.com...

"The wind industry may soon be dependent on a different kind of environmental awareness that has more to do with lasers than ecology. A new laser system that can be mounted on wind turbines allows them to prepare for the wind rushing toward their blades. The lasers act like sonar for the wind, bouncing off microscopically small particulates and back to a fiber optic detector. That data is fed to an on-board processor that generates a three-dimensional view of the wind speed and direction. Subtle adjustments in the turbine blade’s angle to the window allows it to capture more energy and protect itself in case of strong gusts."
