Here we were preparing the sails for a four sail configuration and I wanted to know if the turbine would work with two sails or not so we tried it. I thought it would not work but I was wrong. The rotation was not smoothbut it was rotating. The wavy motion of the flaps will be eliminated once they are manufactured with plastics.

Incredible! What an idea!
