so now you have the banana with ends up in the air, but it can only sit up on one side unless you tip it over by hand correct? now you need to have stops on the outside of the machine so it can only tilt around ten inches up or down on each side from centre now you need to have the centre of the rod encased in Styrofoam like surfboard foam, and fill the tube with water to the tag level.

and let it go, what will happen?, now remember the foam is capable of lifting both weights together, ok so the foam lifts the rod to the tag, but there is now more weight on one side of the rocker yes? because of the weights, so it tips over to the other side, but hang on??? now the foam will want to get back out the other way wont it?

actually no, because there is now more foam on one side, and the foam is the driver, so it will stay there wont it? oh hang on??? but the foam is now down and the water surface is up the other side yes??? no the water finds its own level, but the path of least resistance is still the curve up on the other side and with roller bearings you can't hold the foam down against the water buoyancy??

so will this rock back and forwards forever?

No, it will not rock back and forwards forever.  An object floating due to buoyancy does so by displacing its own weight in water.  You are disregarding the weight of the displaced water.

But I am just a crazy dickhead right??? There you go, absolute g'teed to work. and you know if one works, then you can be sure all six work.

What if one doesn't work?  By your logic, that would mean that they're all bunk.

The error was mine, i did leave out that it needs a crawler, the is the inside of the bottom of the tube must have cog serations and there must be two cog wheels one on each end, what you missed was the inner rod and outer tube were not connected, the outer tube is simply lighter than the rod.

Newtonian math says that any perfectlty formed item that has equal balancing halfs will balance on a fulcrum, yet even in a vacum this is not true, for physics defies the math in real life, even if this item were machined by god himself to be perfect it would still not balance? what is it?

Two circles can never balance on each other, you can remove the top half of the circle to get your semishpere or banana, but even though in this case i agree the math says two equal halves hsould balance, not even NASA can do it, and when the flcrum circle is smaller it gets even worse, the point where maths and physics do not work, and again so much for math.

and yes you forget the tubes are longer and there is no weight fo water on one side as it always finds level

Oh, I see....  now chet speaks for archer!   Learn how to quote, chet.

It doesn't matter if you add gears and cogs.  The thing will just sit there, or at best slosh about for a few seconds after being tipped.

 ZERO Not having performed this experiment [as you must have] im not qualified to comment on your findings    PLEASE teach me how to quote your soooo. good at it thanks   Chet

Yeah I know - why did I care enough to post if I think it's garbage?

But, I admitted that thinking about this stuff is a fun and creative excercise, and props for all of the clever ideas people come up with.  And I can imagine say a high school physics teacher using this stuff as excercises for his class to disprove.

In further thought I wondered why, if perpetual motion is in fact possible, evolution hadn't happened upon it as a limitless source of energy for an organism.  Think of the incredible advantage that organism would gain over every other form of life!  Yet I'm almost certain that no organism uses it (If they did, they would surely be the dominant life form on the planet).  So I'm suggesting that you creative thinkers come up with some biological mechanism that would seem to convey perpetual motion or overunity or whatever you want to call it.  I would imagine it would be chemical in nature, but could possibly involve 'mechanics' of a sort involving protein structures.  Then, if this is as easy as some say, let's build that uber-organism with genetic engineering!
