This is a model 14" diameter x 18" high to experiment with wing design for the rotor. The wings of the rotor are giving lift and not just pushed. The rotor is under power from lift or drag almost all the way around. An actual machine would need to have a 24" diameter rotor and 4 feet high to be useful. I plan on making kits available soon. They will be cnc cut and easy to assemble like IKEA furniture.
The rotor blades are airfoils that have their length nearly parallel to the wind. Much like an airplane with slight wing incidence. On the back side of the rotor the airfoil is reversed and so lift is always a tangent to the center of rotation. There is quite a bit of drag force as the wing turns downwind, but no drag coming upwind due to vacuum.
