3D Printed VAWT - Experimental Compromise

A look an airfoil that is a compromise between the Lenz2 style and the purely lift versions of the turbine. My hope was to design a turbine that would turn in low winds like the Lenz2 but have lower drag and spin a little faster in moderate winds. The result is inconclusive because our winds have been so light or from the wrong direction for the past few weeks. I tested it using the car, and it appeared to behave as expected.
I did not have magnets in the rotor at the time of this video. Eventually, I want to mount the magnets and include a joule thief circuit to light an LED while running at lower RPMs.
