Bessler Wheel Theory by Alex

[fletcher]

Thanks Stefan ..it keels when all the weights [driver & driven] are the same 10 kg's each - it keels when either the driver or the driven weights are changed to 5 kg's leaving the other 4 at 10 kg's - I suggest it will keel with any combination of weights ratio & rod lengths you care to try.

N.B.1. the rods in WM are massless for the purposes of the simulation - if the rods were replaced by rectangles with even a little mass it would still keel but would find a slightly different 'balanced' position i.e. where no torque is produced - if you can't be bothered adding pin friction to everything I suggest you select .... World>air resistance>low pressure    .... as an approximation of some ordinary system losses a real build would encounter [this will slow down & dampen the oscillations].

N.B.2. keeling is an analogy/metaphor for a yachts keel that lowers its CoG, in the process standing the yacht upright at the water line.

I guess its up to you to find a combination that works while Alex & Ralph independently build the thing to cross reference ?!

Okay, here is a picture, of what I mean.
the inner weight is 30 Kg and the outer weight is just 10 Kg.
So via the rod levers you can pull up the 30 Kg weight via the
10Kg weight and the CoM ( Center of Mass) does not go down, but goes to the right side of the wheel,
making it there heavier.
Maybe we still find a solution, so the CoM goes up ?
But I think this will not be found, as when the weights move, their combined
CoM does always go down at least a bit first.
But here in my example movie
alex_harti02.avi
you see, that the CoM goes down and up again
and shifts to the right  side.

Well, I am again then now copying the first quarter weights setup to the other
quarters of the wheel and will study the CoM further...
We will see, if we get then the wheel to shift all of its CoM to the right side and thus make
it heavier there, so the wheel could rotate clockwise...

Stay tuned..

Fletcher and forum members;

I guess its up to you to find a combination that works while Alex & Ralph independently build the thing to cross reference ?!

Due to the amount of interest and the number of members all working on this design,  I wish to set the record straight.

I am not nor will I soon start building this concept.  I will wait until everyone runs their simulations and perchance some real builds are explored.

If you recall, my policy is to build submissions that I deem viable or questionable for those that do not have the resources,  tooling or skills to do it themselves. In this case Alex claims he is capable of building it himself. Therefore I decline.  I am not in the position to be building wheels for those capable of doing their own.

Alex  has publicly given me an OK to build and modify as  I see fit, which I did not have when first reviewing his design.
If a runner is not presented and the present excitement and enthusiasm dies, then I may be interested in seeing what my innovation may provide. For now I have other interests, and will watch this thread run its course.

EDIT:  IMO the simulations displayed here is leading away from the original submitted drawings that I received.

Okay, I uploaded another new movie over  here:

http://www.overunity.com/alexioco/alex_harti03.avi

and the simulation file to it:

As you can see in the movie the
CoM  ( the dotted ball below the axis) moves to the right,
then the wheel turns and then it just keels.

We have to find a way, that the weights will shift again before it keels
again...

But I think, this Alex MT combination can not work this way.
I tried various setups and this was still the best so far.

At least I do know now the WM2D programm much better and
will try now to solve the Milkovic puzzle with it.

Here is a picture for those who have not looked at the movies yet.
You see the CoM ( dotted ball) is below the axis and has shifted to the right
and then the wheel
is behaving like a pendulum
as the weights do not shift anymore inside the wheel
and it just keels.

I guess this only can be overcome if springs will be used, which
are fixed with one end OUTSIDE the wheel and with the other side
to a weight inside the wheel.
But then the syncing of all the spring actions will be very hard to do
purely mechanically...

Regards, Stefan.
