Hi Guys,

Think about a kid swinging on a chain swing in a schoolyard.  -- Here comes the theory--

Say the kid weighs 100 pounds.   If he kicks his feet out when the swing is at its apex he will go higher and higher with every kick to a certain point.  He can do this for hours on end without much effort on his part just by shifting his 100 pound weight.  He can even do it forever should he live that long at the same weight of 100 pounds.   ALL DONE ONLY BY SHIFTING HIS WEIGHT ( LEG KICK) AT A PRECISE TIME.

This is the perfect example of a perpetual swinging  pendulum operating the same way as the very last illustration I posted.


Now lets focus on two kids shifting their weight around on a schoolyard see-saw.

The see- saw will go up and down determined by where the real weight is.  
That weight shift is akin to the kick the kid gives to the swing to make it go higher and higher on the pendulum swing.

The runner ring magnet if properly positioned on top of this articulating device will provide the extra kick as the kid does on the school yard swing at its highest point.

This kick happens on "BOTH" sides of the pendulum swing apex !!!  Lots of power!!!

The force of gravity pulling the runner down the balance beam supplys both the weight shift and pendulum kick.

The real trick is to have the runner magnet distance adjusted to fall to the lowest position just a split second ""AFTER"" THE PENDULUM HAS REACHED ITS HIGEST POINT in the arc swing.  If the runner hits the lowest position "BEFORE" that time the pendulum effect will slowly deteriorate.

That runner magnet will never crash around  from side to side as both end magnets will provide the needed repel/bounce cushioning to keep that from happening.

Well what do you think of this theory guys? Shoot holes in it if you think it wont work. Are we going to make this self runner device operational or what?

Its easy to construct.   Worth a try.

I am going to do it.

Hi Guys,

Just to lighten the whole illustration you see above I found that stacking many small rectangular neos together works.    My runner ring magnet measures 3 inches thick.

I made a small powerfull bar magnet that measures 3 inches long. I stacked twelve 1/4 inch thick grade 50 neodymium magnets together and formed a 3 inch bar magnet that  does the same repelling job as the large fixed end ring magnets you see on the illustration.

Its way smaller and much lighter than the fixed end ring magnets. Just as powerfull if not more so. Much easier to mount.

Ok here is something that I would like a person that likes math to figure out:

If I measured the weight of the whole balance beam, beam magnets, minus the weight of the frame what  math might you use to determine the weight of the pendulum itself and the lenght, weight of the pendulum rod? 

Something that would put me in the ballpark constructing this device.  Realize that the weight can be adjusted by screwing the weight up or down on the pendulum rod.

The longer balance beam is illustrated with magnetic (repel) ends not yet mounted on the beam. Next I will make the support frame. Plastic sides neeed to be installed to keep the runner from rolling off the beam.   Need to play with the runner weight verses the pendulum weight. Then comes the exact moment when the ring runner bottoms out ( bounces) on  repell cushioned forces mounted on both beams ends. 

That split second timing is the key or holy grail that will determine if this device works as planned.   In that split second is the extra bouncing kick the pendulum needs while at the top of "ALL" arc swings to keep it swinging forever.

you rule tom,

i guess i forgot to tell you, it's like balancing a chair on two legs.  good luck though!!!  i just figured it out myself.
