maybe see the french-section:

cannot say anything about it, because i cannot read french

there was also a german patent dicussed here somewhere in the forum, with a gravity wheel concept with two turning wheights on each end of the lever. didn't found it... the demo unit was housed in a metal barrel. maybe also in the french section... but also discussed in english somewhere...

@all,

does this idea have merrit?  i think it does!!  i just went back and found on the second page of gravity devices,  "the living energy machine"  remember that?  man that thing would fly!  this looks kind of like that only verticle with an outer ring.  that might be interesting, when you think about it.  the biggest question i have in my mind is, how does the outer ring actually move?  and if it doesn't, is only extra friction for no reason.  everyone take a look and let's see if we can establish a way to make this baby roll.

lol

ps: check out the video on youtube.

@Imgoingnuts

Yes you are. Just joking. lol

Really, when you come on the board with a nice design and just ask "will this work", what else do you expect us to say. No explanation on how it's supposed to work, nothing. So we have to look at your design and figure out what you are trying to show.

So here goes.

If your design in made so that the red masses afford more weight on one side then the other in order to push the revolutions, it will not work and you can see this right on the design how the weights will translate in the next movement.

Top right - increase
Center - Right - decrease
Bottom right - decrease
Bottom left - decrease
Center left - increase
Top left - increase....... So the left side wins.

In your design, the mass is in small wheels and this will kill any ability to exert any type of real leverage on the big wheel. Also those red masses would have to be 3-4 times bigger to actually make any real difference on the whole mass of the wheels.

Six wheels with gears means there is at least 2-3 teeth engaged at all times per wheel, so in total you have 12-15 teeth engaged in the system. This alone is a killer.

Also your teeth design shows you need more experience with gears since they do not engage in the angles you have shown. Look up gears, teeth, pitch angle, etc.

Now here's the hardest part. Every wheel in the system would have to be perfectly balanced, including the outer wheel. Also the outer wheel will have to be secured somehow in another sliding mechanism to keep it in place and this will also add to friction.

So all in all, I would say DO NOT BUILD THIS this way. You will need to do alot of homework first and especially when you do one drawing, you have to do many more in different angles to see how the balance ratio is over at least every 2 degrees for at least 45-90 degrees. That's 20 to 40 drawings.

Hope I'm not coming on too hard on you. Having ideas is great, and knowing when to stop is also great. If one of these is out of sync, guys run into problems and all waste time.

My 2 cents Imgoingnuts ...

Any over-balanced wheel is a more mechanically complex version of a simple pendulum rod & bob.

Over-balance wheels & pendulums have a lot in common - they start in balance [CoG/CoM directly below the axle which is the usually the Center of Rotation] where they have zero torque & then must be 'manually repositioned' into a state where they are Out Of Balance [OOB] & have some torque - after release they must be able to move & in doing so they loose some of their Potential Energy from vertical height they started with - their CoG/CoM moves in an arc downwards & towards the vertical line beneath the axle until they have no more torque & have reached their lowest PE, called the 'keel' position because it's like a keel on a sail boat - the acceleration they achieve is related to the CoG offset & the frictional forces slowing them down [drag] & other system losses such as windage - once they have achieved a velocity at the nadir they have accumulated a certain momentum [angular inertia] - after this the momentum will continue the 'swing on' until the momentum is depleted & it stops its upwards climb, thereafter it reverses direction as the gravity force [which has been acting at all times] overcomes the momentum.

In order to create a self sustaining over-balance wheel IMO you need to achieve one of two things 1. accumulate extra momentum on the down swing or 2. reduce the counter-torque on the up swing or as is usually experienced when trying to reposition the internal weights into the OOB position to repeat the cycle [after normal system losses] - if unable to accomplish this the device will oscillate until it settles down in a position of least PE & its CoG/CoM does not produce any further torque, either positive or negative in direction.

If you can look at your design & either see where this extra energy is going to come from to give it extra momentum or you can see how to reposition the weight disks without the normal complement of back-torque then I would proceed with a model build, actually I have seen similar designs animated but initially done on Working Model software using gears.

Just My Thoughts !

Just a suggestion, If I remember right, metric gears are measured from about the middle of the tooth where they mesh and they are much easier to work with because, I believe, the number of the teeth also corresponds with the size. In that case, I believe, what you would need are gears of equal size. If you get there before I do, let me know!  :)

think this can be simulated in working model 2d: http://workingmodel.design-simulation.com/WM2D/download.php
