I have been able to improve the design substantialy. The ball is now approaching the entry point on the uchannel at a much higher elevation than in the first video.
Here is the youtube link- enjoy!

I''m sorry to have to break the news for you....but you are light years away from self looping your SMOT.
The elevation is sky high considering the ball having used all it's energy when aproaching the "staircase".

When I first started the elevation between the ball and the top of the uchannel was 2" at the entry point. I have reduced this to  1/2". The ball speeds up when it moves from the connecting uchannel onto the glass plate. It is picking UP energy and NOT slowing down. Another gain of 1/2"
and the ball will enter the uchannel of the SMOT. There is NO GATE at the SMOT entry point
the ball will in effect be sucked up into the magnet configuration and the roll thru will continue.

I have just posted a third video with an additional SMOT to help clearify what is happeneing

all I can say is prove it..... you say its possible, so do it already :) don't get me wrong here, I would love for you to succeed, but you wont succeed convincing people it will work when you haven't got it to work (close loop that is)

It looks to me as there is a weak repulsion force at the entry of the Smot gate!
This means you have two forces to combat before you can get your Smot self running, elevation and repulsion.
I look forward to your next video. Good luck.

There is no repulsion force at the entry only at the exit. The SMOT attracts at the entry point.
Elevation is the challange.

Agree 100% but I thought the group would find the development interesting.

I can't speak on behalf of everyone, but I for one am interested in the development. I too am trying something smot related. When i am done ill post a video.

Elevation is the challenge.

OK, prove this by moving the aluminum carrier well below the Smot entry and then roll the ball
gently towards the entry until it gets sucked in by itself from a clear and visible distance.
The aluminum carrier should not lean in any direction...it must be absolutely horizontal.
You could show this in your next video.

@billmehess: The problem is not only to raise the ball 1/2 inch at the end of the track, but the ball are also repelled by the magnets before it reach the 1/2 inch step, and therfor loose kinetic energy in addition to the friction in the track. Try to raise the track gradually 1/2 inch so the end of it is aligned with the SMOT. Then you can see that it will not be able to enter the SMOT for a second, or possibly endless run.

The ball will be repelled in this area because the magnets are attracting eachother, and it requires energy to enter the SMOT itself. Putting the magnets in repelling alignment will force the ball into the track, but not be able to push the ball upwards because the field are zero half way up the track.

In both ways the ball will gain its kinetic energy due to gravity, minus the attraction to the magnet which slows down the acceleration in the gravity field. So for these reasons you cannot close the loop for a self sustaining SMOT. There is always a reaction to any actions applied to the ball - wether it is magnetic or gravitational.

Wish you could succeed. Good luck!

I understand now why he is so worked up.... what you deny is clearly not the point here... of course it can enter the gate no problem..... the REAL point is that the ball can NOT escape the end gate on a level (hence why he has it go off a drop)... getting it into the start from a level is easy, getting it exit from a level is impossible...

To : Fat Chance, LowQ & Poit

Of course the ball can enter the SMOT. There is NO replusion here, the SMOT eaisly sucks the ball into it. Look at the video with the two SMOTS, the SMOT3 001 video, and you will see that CLEARLY in the second what I called a "down and dirty SMOT" I built it just to show this effect.
Again there is NO replusion only attraction at the SMOT enterance.
Any slowing down is only due to friction!!!!!!
The ball enters the magnetic conf. at a good speed. It exits the scoop at a good speed. What I have done so far has been able to reduce my initial height from about 2" to less than 1/2"
Will I be sucessful in this last hurdle, time will tell.
 Potential energy is not a problem, it is a non factor. As far as the ball not being able to leave the SMOT due to height every video shows it doing just that.

@billmehess:

My 2 cents.

When your ball exit from the gate and fall down, then it lose some energy
in the crash with the bottom; you must to smooth this fall
to gain energy in this phase with a gentle slide. Not too gentle
otherwise your ball don't exit from the gate and not too steep
otherwise your ball wastes energy.

Bill,

Here is something you may want to try.
The track is level.
