A horse trailer turned office serves as a base-of-operations. Inside, researchers use a computer connected to sensors on the turbine to detect its performance and changes made by a countless number of tweaks. Cut-in wind speed is 3.6 m/s (8 mph). Shut down speed is 32 m/s (72 mph). The turbine maintains a tip speed ratio (TSR) up to 18 m/s. After that, TSR is adjusted to maintain torque and maximum blade speed.
