@ Hans:

I just got back from reading the peswiki link that you gave earlier.  There are some pretty nice replication attempts there.  Thanks for posting it along with the information.

Interesting idea you have there for cutting out the middleman (electricity) in performing work directly.  The old machine shops ran this way. (Think Wright brothers machine shop)  They used mechanical energy as mechanical energy.  With this line of thinking, I can envision a central "power plant" in a modern home where generating electricity is but one of its many functions.

I just hope Lawrence does not see your topic or he will be telling us how you are "leading out" gravitational energy as he has predicted all along.  Hey, do you think this device might one day power a flying saucer? (Just kidding)

Seriously, I believe this device to be the most promising thing I have seen here on OU. com, or any other site.  I would wish you luck but I know that engineers do not depend on luck.

Please keep this topic going even if it gets bombarded by naysayers and the like.  As I said before, this will be difficult to replicate but the concept is so perfect.  This device must get built.

Anyway, take care and I will raise a glass of beer to your success.

Be well my friend.

Bill

Cool design  !!!
But is someone building this ? or is it only on papers ?

A good collection of replication attempts is shown here :

As stated by AB Hammer there are no runners yet but it looks like some of the attempts could be modified with the information Hans has created that at least would try out his approach.

@ AB Hammer,

Go for your life Alan. This is not my thread it belongs to us all. Any comments or designs are welcome, the more the merrier.

@ Omega_0,

Yes we are preparing to build. I am still having a few problems to get the control mechanism sorted out. There are a number of options, what I am still looking for is a simple rugged and precise mechanism that does the job. Progress is being made though. The engineering drawings are being prepared right now for the wheel itself which is much modified from Pop Keenie's layout. This can then be built already and the control mechanism can be added later.

@ am1ll3r,

I can see what you are trying to do here but where is the power coming from to drive the mechanism?

@ Bill,

Yes I can see how Lawrence is going to try to get the credit for this.

I hate you Hans,    You are causing my mind to work overtime  Or at least what is left of it.. 
Pretty soon I am going to think about this morning, noon and night. 

As I am trying to understanding how this might work I am grasping the net gain in the systems is the difference in the leverage points between the inner weight and the outer weight.
I think I have an idea of how to make this work without the lever arm and without a lot of additional mechanics. I really stink at drawing so let me verbally explain using your drawing.
Take a copy of your drawing and remove the level arm and spring system.
1. Now take the view of the inner rotor being allowed to continuously rotate clockwise and the outer one was rotating counterclockwise continuously. There would have to be some 1:1 gearing on the output shaft so lets say the inner rotor is fixed to the output shaft and the outer rotor rides on a bearing over the output shaft. This outer rotor has a gear attached to it that drives another 2 gears that interface to the inner rotor. The purpose of the gearing is so when the outer rotor goes down the inner rotor goes up an equal amount. Should be simple enough.
2. Now make your outer rotor twice as wide.
3. Now make the slots deeper into both the inner and outer rotors so that 2 weights will be able to be side by side. In fact make it extra wide. Put one weight on the outer rotor and one weight on the inner rotor with about on weight width between the two weights..
4. Now what would happen if you just bolt one equal weight on the outer rotor and bolt one on the inner rotor at the 9:00 o'clock positions across from each other ? .

The question that I need an answer for before I continue is if the outer weight will go down while the inner weight will go up because of the difference in lever arm length from the common shaft to the weight positions ? My mind thinks the outer weight will go down to the 8:00 position and the inner
one will go to the 10:00 position or until the weights line up with each other on the left side. Is there a software program to test this out ?

5. If this works then all you need to do is to leave the lever arm off. Instead insert an solid blocking bar from the 5:00 oclock position to the 10:00 oclock position so that when the weight shifts from the outer to inner rotor it is trapped in the inner rotor until the it reaches the 10:00 position. Have the slot more like to buzzsaw tooth so at the 10:00 position it releases slightly sooner than the 5:00 oclock position to give in a slight edge.

What do you think ?

@ hydrocontrol

I'll give your ideas some thought.

One of the things though you must remember that fixed gearing ratios don't work. They do not alter the relationship between the geometry of the inner wheel in relation to the geometry of the outer wheel. That is why a reciprocal movement is paramount.

Good luck to you !!
And please keep us updated.

That old rusted model looks interesting and I wonder why someone would build such heavy wheel. My advice is to start from a small model and go upwards in scale later.

That's the sound of progress......
