Google patented a technique to enhance tracking accuracy of its flying wind turbines.
Google has been working on wind turbines for some time now, since its purchase of the energy company Makani Power in 2013. These wind turbines can access stronger and steadier winds at higher altitudes to generate more energy with fewer materials. New patent tracks the wind turbine tethered to a ground station as it flies around a substantially circular path. The tracking helps the tether termination mount to avoid twists in the tether. Tether twisting can have an adverse effect on performance.
