Thanks Ron you have found the patent. It was filed by Hamnid Rahai. Thanks a million
I will be studying it to see if I can replicate the design. Hamid claims this design has about the same lift characteristics as found in HAWT. If this is true it will be a major breakthough in design of the HAWT. Near the end of the artical in the summary he makes the claims. He has tested the design in a wind tunnel proving it to be 40% more efficient than the Benesh airfoil.
