    Another advantage of the helical twist is that the blades generate torque well from upward-slanting airflow. This is negligible in open country, but tall buildings and cliff faces generate a bow wave which directs airflow up and over them. Turbines mounted on building rooftops or clifftops are exposed to significantly slanting flow, and the Turby can extract more useful energy from it than a propeller-type turbine can.

    Wish we had a few thousand of those on the divide in Denver.

    Gliders use that effect to stay aloft for hours at a time.
