telecom,
 
The second design was to keep the "B" sprocket stationary and have the generators mounted on "C" as before.
When "B" is mounted stationary then "A" cannot rotate by torque on "C".

If this was not true, then we could simply apply a torque to "C" with a spring to a connecting arm (steam engine) and the device would run forever since the spring would apply torque but never unwind.
 
Because the torque is applied into "B" from "C", then it should also be possible to use "B" as the generator drive and nothing else changing. Simply a torque increaser.
 
I show all the designs because sometimes it is the reduction in design that also induces a reduction of operation.
One can always backup to a previous design to see what changed.

Hi Lumen,
this sounds more preferable in terms of wiring the generator being stationary, rather
than rotating like crazy.
May be you can draw a picture of this setup as well, if this is not very hard to do?
It would be interesting to run some calculations of a possible output for certain
rpm and the weights.
Thank you!

telecom,
 
Before you get too far into this, I plan to do some testing on this because something is missing.
Suppose "B" was rotating the same as "A" but with increased torque. Couldn't one then just place a connection between "B" and "A" and it would power itself?
I would think not since a connection of "B" to "A" would just simply make a flywheel.
This is where something is not understood. Does this apply to all the different designs, or just this one?

Hi Lumen,
IMHO you can't bypass the weight attached to C, which actually works as a torque
increaser under the centrifugal force.
But since this is not a textbook concept, everything is possible.
It would be really great if you can find some time to test this exciting concept!
Thank you.

telecom,
 
I have another project to finish this week, but hope to be building one of these sometime in January. I first need to decide which one to build.
 
I do like the concept of trying to build a gyro that runs itself from centrifugal force. It would seem interesting if a gyro could supply more stability than the torque required to operate it.
 
I think this could easily be tested with just a gyro and a drive system that provides all the rotating energy up through the pivot point.

Hi guys,

I tried a version of this idea after watching this physics lecture by Walter Lewin (https://www.youtube.com/watch?v=XPUuF_dECVI). Near the end he demonstrates a gyro suspended in 3-axled gimbled arrangement as you might find in an old style aviation gyro. By placing a weight on the end of the gyro's axis, he demonstrated the resulting precession of the outer frame. As he puts it, "The spin angular momentum is chasing the torque." So it seemed to me the precession torque could be tapped from a drive shaft connected to the lower bar of that outer frame.

There is indeed a precessional torque to be gained by placing the weight on that axis when the gyro is spinning. However, apart from the argument that the axis is actually "dipping" slightly and if prevented from doing so the precession stops; there is a more serious problem which prevents power from being tapped from this process. That can be seen the moment you physically resist the movement of that outer frame, which is exactly what hooking it up to a generator under load would do ... The gyro immediately responds by flipping downward. That is, it reacts as if more weight has suddenly been added to the end of the axis. There is an equal but opposite reaction occurring, and again it almost needs to be seen to be believed since despite it making perfect sense to "nature", it appears non-intuitive. Unfortunately, it rendered my hope of a gravitational gyro drive mechanism unworkable.

Had Professor Lewin gone one step further in his demonstration to show this effect it would have save me the trouble, and it would have added one more sense of wonder for his students.
