The venturi Tamer Wind Orientation problem is solved here.
Think of an old style military parachute.
The tamer is already designed like an old style military parachute that catches the wind!
The apex of the Tamer is the narrow end of the tamer. The wide open end that catches the air is attached to the pole and allowed to pivot around the pole in which ever direction the wind is blowing... correctly allowing the wind into the larger end of the tamer, thus setting up pressure differentials for the venturi effect to do its thing and spin the blades like a banshee...
If you don't get it then visualize this... The correct wind orientation will work just like a parachute attached to a vertical pole.
Now we have a venturi Tamer.... Named it for you to, I accept stock, cash, or money order...
Just thinking outside the box for our Tamer friends.
