Giving wind turbines a “spider sense”

Okay, the “spider sense” part is a bit of a stretch, but being a Spider Man fan I had to throw it in. Actually, what I’m talking about is a new type of LIDAR (Light Detecting and Ranging) device that’s designed to integrate into the nacelle of a wind turbine. The laser system, developed by a Manassas, Virginia-based company called Catch The Wind Inc., projects three beams up to 1,000 metres in front of a wind turbine. The colour frequency of the beams change when dust particles pass through them, and the colour is directly proportional to the distance of the particle — and thus the wind. Using this approach, based on the Doppler principle, the three beams work together to calculate both the speed of the wind and its direction.

Why is this important? Continue reading Giving wind turbines a “spider sense”
