SMOT - Close to closing the loop ,second video-BIG improvement

A magnetic array on the return slope Will absolutely result in a sticky spot. All will be revealed soon, very soon.

@FYI All,

I's like to point out that;
A ball running on rails where all of it's weight is supported on tracks
is a different thing then a ball rolling on it's circumference on a flat
plane.

A sphere will have a "coupling factor" between it's rotational
momentum and it's forward momentum. That coupling factor is
a gearing ratio between the rpm representing rotational momentum
and the forward velocity representing the forward momentum.

So by varying the track width is possible to change the gearing ratio
of the stored energy in the runner within certain limits. This can
cause the ball to act as a flywheel. This is not the same as a runner
always rolling on it's circumference which will always have a unity
transfer function.

Bill,  any progress on closing the loop?

In any case, there should always be a unity transfer function (?). The difference is the coupling factor which determine the forward speed versus the rpm of the ball. In any case the mass in the ball is accelerated to a given rpm which always correspond to its forward acceleration - regardless of the coupling factor X : 1, or if the ball rolls directly on its circumference 1:1. However, in practice, losses are more likely to occour when the coupling factor are very high (high rpm, low forward velocity).

Still working on it daily. That last 1/4" is proving illusive. But since I have made up 2 1/2 " of a 2 3/4" drop I believe the remaining  1/4" will be overcome also.
