This looks good in theory.
I see two issues, you would have to have a mechanical way of closing the flaps.
That would cause drag as at a point the springs will overpower the wind as they close, this will create drag.
The second if using wind would work you will have the issues of finding correct shape to always open with minimal effort, so in light wind conditions it wouldn't want to open due to the weight of the vanes themselves.

@dkenny The wind catches the edge of the blade that is rotating away from the 'front', forces it open, and then pushes it (unil it reaches the back) to keep the turbine spinning.

what move the fins back out? its not clear in the video
-
Uh, roof turbines and spinning chimneys do exist. They extend this concept by having 50 or so blades, but angle them, so that one side catches the wind and the other side is aerodynamic.
-
Windmills do not work that way. Good Nite
-
The concept is good but the best way to implement this is using pliable materials that can retract in the face of the wind and open to catch air. Birds do this all of the time. Were you discouraged by your detractors or did you build the unit?

Rube Goldberg material right here folks.
-
Just curious as to how one would overcome the issue of the fins/flaps or whatever staying permanently open due to the centripetal force?

@wuerp I like the idea even better!
