@Harvey

A stationary steel ring around the outside edge? Only 2 warnings on this, A Ramp and Friction.

@CLaNZeR
The only hope for this one in this configuration, is a mechanical latch that will grab when low and release when high.

Good luck

What are your thoughts regarding the design?
Is there a difference between magnetically moving a weight vs. mechanically?
Do those difference impact the operation of the Gravity Wheel?
When you first saw the design, what dimensions did you give it in your mind? Why do you think that is?

I think the design is very creative.  But I also see it to be a more complex and therefore friction limited version of a gravity wheel with simple ramps at 6 and 12. 
The difference I see in the way that magnetic mass switches raise the weights is that it is relatively quick.  So each switch magnet is in it's optimal location (close to axel or rim) for the majority of the rotation.  The design you show only accomplishes this at 3 and 9 where at all the other positions the weights are moving away from the ends where they produce the greatest imbalance.
The mass switches reguire all the energy to fire the magnets in a single impulse, causing a cogging effect.  The design you show moves the weights gradually so there would not be that impulse and it would turn smoothly.  But I believe smooth acting magnetic ramps could also be made, so no real difference.  I am not sure if magnets or mechanical can be made with the least amount of loses.
I didn't imagine the design in any specific size.  I only looked at the mechanics involved.  I would say the size is limited by the linear bearing each weight rides on to move radially.  Could use miniature linear slides like in Clanzer's SOG.  I believe I am thinking in this scale due to the economics of building a test unit - trying to minimize cost.

good building clazner u need longer travel for tube magnets

Very good and sturdy wheel
IMO, the displacement of weights by sliding magnets for such a short distance would not make much difference here. Compared to the weight of whole wheel, these magnets won't make any effect (especially while spinning at reasonable speed) because they won't unbalance it much.

What I see is, they barely escape the influence of that strong stator magnet...which only means one thing - drag and stickiness.

Anyway, you must have thought something before cutting the tubes so short, so give it a try and let us know....

My suggestion is to not to build the whole wheel at one go, but to go step by step.
(I made this procedure for myself, but I'm pasting it here for you and for all)

1- Build the wheel only (which you have already done nicely)

2- Balance it perfectly (it should stay still when let go)

3- Put just one tube on it (going from center to the rim) with a magnet in it.

4- Latch the magnet on the rim side and let it go from 12 o'clock. The wheel should rotate to 270 deg on its own (say CW). If it doesn't, its not unbalanced enough and you need heavier magnets.(or lighter wheel). Replace and repeat till its right.

5- Install the first stator magnet at the center of the wheel. Latch the slider magnet at the center end and again let it go from 12 o'clock. The magnet should get pushed to the rim and get latched there and again the wheel should go 270. If this fails, you need a stronger stator magnet. Repeat.
(Don't cut the tubes short to get it latched, because if you do, you will need to make the wheel smaller as well, and the leverage will be lost, but if you do, make the wheel smaller and lighter)


6- Put another identical tube and magnet exactly opposite to the first, so that both are on the diameter. The wheel should balance again.

7- Latch both the slider magnets at the center. (note that the bottom slider magnet is getting attracted to the stator, which is creating a sticky, so shield the stator magnet with mu-metal at the bottom pole).

8- Let go the wheel from 12 o'clock again. The upper slider magnet gets pushed to the rim and the wheel goes 180 deg, when the other slider reaches the top and gets pushed to the rim as well. The wheel balances at this point and will come to rest.
If the second slider magnet fails to reach the rim, while in rotation, your stator magnet is too weak.
If the second slider magnet hits the wall (which will be at 11 o'clock roughly) and fails to reach 12 o'clock, your magnets are too strong.
Replace and repeat.

9- Install an identical stator magnet at the bottom. It must be identical. (Ensure by replacing the center stator and doing the step #8 again)
10- Let go the wheel from 12 o'clock, while keeping both sliders latched at the center. The first slider should get pushed to the rim and turn the wheel by 180. When it reaches 6 o'clock, it gets pushed to the center, while the second slider which is at the top gets pushed to the rim. The momentum of the wheel should be enough to take it past 12 o'clock and re-start. So it becomes self starting !
If it fails to complete 360, well....the momentum was not large enough to break the repulsive wall and the magnets are too strong. Try adding non-magnetic weights on the wheel's rim. Or replace them and repeat.

If it does self start and completes more than 360 degrees, you have shown that it is OU and can stop there. The world will take it over and produce a big generator out of it. No need to invest thousands of dollers on stuff and instruments ... no need to show LEDs glowing ....

Now its a mere engineering exercise to add more tubes and stators along the rim..... any kid can do it.

Its better if you go on recording weights and such and plotting graph while doing intelligent trials (not hit and trials). Because you will get and idea where the sweet spot is when you see the graph. Remember that if there is OU here, it will be very tiny and its absolutely possible to miss it.

You will find that it will take days and months to finally see why it will work or why it will not. Don't give up....At most you will prove that this design is non-working and enlighten everyone....
