This blade design was no accident. It was arrived at in maximizing the airflow deflection that results in the blade driving force, otherwise known as "lift", and minimizing the profile drag. The string that can be seen in the corner of the photos was there to keep the rotor from starting up while the photo was taken. Startup is not a problem here and it will even start against a load. Other views I have posted show the blades running at high speeds similar to the small horizontals. It lights the LED lights from its direct coupled axial flux generator. Unlike the Savoniuses, this can be readily scaled up both in blade length and rotor arm diameter.




(Only one blade pair is fully assembled while the other three were just hung on their arms for the photo.)

No one has ever claimed that blades like this have been tried anywhere else to my knowledge. Most everyone seems to feel they don't work until they see it start up and run.
