One More: Much Ado About Nothing!
There goes:
1 is a drum wheel.
2 is pair of broken axles.
3 is inner rim of 1.
4 is a pair of pendulums on either side of 3.
5 are small wheels, same diameter of 3, with their axles on upper ends of 4.
6 are L-shaped lever-arms, connecting 3 and 5 to rotate at same speed.
7 are identical strings.
8 are weights swinging on pairs of 7, on out rim of drum wheel and on ends
of horizontal arms of 6.
The wheels are expected to rotate clockwise, with weights swinging upwards nearer to 2 and downwards further away from 2, weights resetting overall positions every 45 degrees turn.

Described as this concept is, there is little more to ask me.
Methink!
If I just hinted some farfetched idea, withholding details as ideas safeguard, replies would have been forthcoming, maybe overtaking 275 pages.

1 is a flywheel/wheel.
2 is axle of 1.
3 is inner rim of 1.
4 are identical pendulums.
5 are pivots of 4.
6 are bobs/weights on 4.
7 are diametrically opposite pulleys on 3.
8 are levers connecting 6 to 7.
Simplicity of design.
1. The flywheel is the prime-mover.
When wheel turns, in any direction, it activates both pendulums to swing to and fro.
2. A single swing will push and pull flywheel one full 360 degrees rotation, exchanging momentum with rotating flywheel.

raj,
"Simplicity of design" a good title for something that is impossible to function as drawn!
I do hope your real research and designs are not this humorous!

What is supporting it? Surely not the axle?1 is a flywheel/wheel.
Obviously it is meant to turn with the wheel, but it can not do this as we delve deeper in the design.2 is axle of 1.
Fair enough, all rims making up a wheel have an inner and outer.3 is inner rim of 1.
What is suspending them, how long are the rods, they appear to be hung to close together to sync with radius of #2 the axle.4 are identical pendulums.
Everything needs a hook or nail to hang something on!5 are pivots of 4.
Got to have a bob if you want a pendulum.6 are bobs/weights on 4.
pulleys? why pulleys if they are only for connecting levers (#8)7 are diametrically opposite pulleys on 3.
This is the fun part! How do these levers not only cut through the axle, but must also pass or circumvent each other per revolution?8 are levers connecting 6 to 7.
I do hope your real research and designs are not this humorous!

@ Ralph!
This should answer some of your questions.
N.B: my concept build attempt is very poor. My apology.

re: One more: Much Ado About Nothing!
I am, hereby, humbly requesting forum members and guests to spend some minutes and ponder on the concept I am presenting here, on this thread.
The drawing below, is my current masterpiece in simplicity of PM wheel concept.
Two pendulums swinging simultaneously, on separate pivots on separate stands (as in my picture above) and a common pivot on either side of a flywheel/wheel.
The drawing shows the flywheel/wheel in a balanced state, but both pendulums are at rest, trying to swing towards the flywheel/wheel.
Now, when the flywheel/wheel is given a push or pull, it will rotate, pulling on the pendulum downwards, on the ascending side which will provide some force to the wheel, as it swings towards the wheel negating the force the wheel will need to push the pendulum upwards, on the descending side.
As the pendulum on the ascending side reaches its lowest position, the pendulum of the descending side will reach its zenith position, and instantly begin to swing downwards, as the flywheel/wheel continues to rotate, thereby providing some force to flywheel/wheel, to push back upwards the other pendulums towards its starting position and beyond to its zenith position, only to reset the up and down swinging cycles, while PROVIDING continuous angular momentum to flywheel to rotate.

re: One more: Much Ado About Nothing!
This drawing should help you understand the accuracy and ratio of the dimensions of all the parts:
This is how I see this wheel to behave:
1. From start, the flywheel has to rotate any direction, the pendulum on the ascending side will swing downwards to its lowest/balanced position, providing its downward momentum to the flywheel at the same time, while the pendulum on the descending side has to be pushed upwards to its zenith position by the rotating flywheel, thereby losing some of its momentum.
2. From then onwards, the pendulums will be acting against one another, one swinging downwards helping flywheel to continue rotating, the other being pushed upwards to its highest point when, instantly the pendulums reverse/switch their roles.
3. The pendulums will seek their equilibrium and point of rest, but as long as they are helping the flywheel to rotate one after the other, by providing angular momentum to the flywheel, the pendulums will not find equilibrium and their resting points, unless stopped by outside force.
4. A build is the only way to find out if my vision is correct.

re: One more: Much Ado About Nothing!
I'm sure I've got something wrong here Raj - but here goes.
Initial Push is just for 1/4 sec even tho you can still see the directional force arrow thru the sim i.e. it is not contributing in any way.
Corrected now I think. Don't know why the files not showing raj. Haven't got time right now to sort it out.

re: One more: Much Ado About Nothing!
Dear Fletcher,
How do I view your avi files?
AS POINTED OUT above, the flywheel/wheel and the two pendulums are AT REST to start with.
A push or pull of flywheel (By outside force) is required to get them into motion.
At start of motion, flywheel will rotate as per given push/pull momentum.
Pendulum on ascending side, will swing downwards to lowest and resting point,losing 0.2 unit height/P.E,(Check my drawing) while adding its momentum to the flywheel.
Pendulum on the descending side will be pushed upwards by flywheel to its highest point gaining 2.0 height/P.E, (Check my drawing), flywheel losing some momentum, but can still rotate for some time.
After this initial motion of few seconds duration, the flywheel will continue to rotate, the pendulums will continue to swing, one pushing the flywheel, the other being pushed by the flywheel, one gaining P.E and the other losing SAME P.E alternately, and at all time, adding their downward momentum to the flywheel.
The question that needs to be answered, is whether the start/initial
momentum given by the outside force to start the motions, will be lost or will the motion/swinging momentum of the pendulums replenished the flywheel's overall momentum, for continued rotation.
Do we have here, a case of NEAR-Linear momentum of pendulums and angular momentum of flywheel working together, being conserved???

Trying the avi attachment again.
ETA: Looks like some one else will have to make and post an avi for you Raj. Mines just not working for me.

Nope - don't know why I can't see the avi file to upload.
Maybe the rest of you can ?
