No, the change in distance between the tracks and the change in radial distance from the orbit center is necessary for the track to engage the balls at a different distance from their center as they move and allow them to follow a perfectly circular path (respectively), and from this the torque differential arises. If you are speaking from knoledge gained from watching the animation in a previous thread, then I should point out that the anomolous weight distribution (more balls on one side) is a result of the torque differential induced by the track and is not the source of the movement, but merely a convenient, and oddly unavoidable, result of the true driving principle, torque differential. It's really hard to explain without a diagram, I'll see what I can't do...

: I don't think I have. Yours may be different but from what I sw of Colishaw's the track change wastes energy.
