You got it brother. And the rebound effect pumping the ball back in toward the hub reduces ball weight drag on the wheel... as the ball gradually falls away into the golden ratio orbital loop for the next cycle.

I know the whole thing is made of solid parts but the wheel in motion is fluid. Think of the balls as being a ball of solid water, the wheel as if it's a stream, because it produces a stream of electricity from the generator.

Stream begets stream.
