An interesting thought has occurred to me Rick. As the wheel speeds up it will reach a speed where the centrifugal force will begin to cause the water to not want to move back to the center. So that will be a self regulating speed control. As the wheel gets loaded and slows down the water will again flow more freely back to the center and increase the torque of the wheel. I am really looking forward to someone building this and trying it out. I just don't have time myself right now to take on a project of this size.

Great work so far!

Take care,
Carroll
