Wow! Thank you all for your great replies. Low-Q and excessAlex, your diagrams are great! It's so good to see all of your ideas. I am taking in and processing your comments and insights. In addition, I am putting together an animation to illustrate the implementation which I have been imagining.

Here is the operation of the magnets - how I imagine it would work. Green path activates the top magnet. Red path activates the other magnet. A cam on the wheel lifts the left side path into a 60 degree alignment.

The vertical path is always fixed. The other path is fixed only when the magnet is sliding back and forth.

Here is an experiment of magnetic cancellation. I used speaker magnets. The two bottom magnets are fixed - not moving. The upper magnet is freely sliding on the table. Look at the small gap between the "free" magnet and the other two magnets, and still there is no sign of attraction. A guide prevents the "free" magnet to fly into the blue magnet. This is total cancellation - just what we want.

I did now the 60 degree escape experiment with guides. Problem found!
The two magnets will not escape the center magnet. The attraction between both magnets and the center magnet is greater than the repulsion between the escaping magnets. Two attractions vs. one repulsion so to speak. The attraction wins and will make sure the kinetic energy that is gained in step one will cancel out by the required energy to make the 60 degree escape.

So basicly we can say that this design will not work. This is bad news

The 60 degree vector will allow attraction in step 3, while there is no attraction in the 90 degree vector in step 2.
So what made me blind was the cancellation BETWEEN the other red magnet and the center magnet, while I forgot the attraction in the 60 degree angle where the movement in step 3 actually is.

Well, never mind the explanations. It will not work $:-\$

Vidar,

Here's my attempt at making the attraction and repulsive forces equal. Let me know what you think. Maybe you can run a simulation of this. The gray in the image represents a ferromagnetic material, and the green is a non-ferromagnetic material used as a spacer, such as plastic. The back-side has a greater repulsive force, while the front-side has a greater attractive force. They should cancel each other. The only downside is the small edge effects with the ferromagnetic material. This could be minimized by not over-saturating the ferromagnetic material, and to leave a greater distance between the ferromagnetic material and the two approaching and departing magnets. Also note, the small gray areas located between the poles of the magnets on the side-view can be dis-regarded, that was due to me using that color as a stroke color while drawing.

Thanks,

GB

Edit: After second thought, this won't work either. Solving one problem creates another problem, LOL.

Just what I was thinking too. You will change the conditions in step 2 also. I honestly think that Nature is hard to fool. But we never give up, right?

I think the "zipper motor" is worth a try too. I "know" it won't work, but I would really like to know what exactly do prevent the zipper motor to run forever.http://www.overunity.com/index.php?topic=10417.msg275686#msg275686

I'll buy some "rubber magnets" which I can cut into triangles and see if the right part in the picture (in the link), will separate as I think it will. If it does, I must try to complete the cycle with shieldings on the left side.
