So I do not have a self accelerating flywheel.
What I do seem to have is a constant velocity interaction.
I will label the two main parts as a drive disc and a reaction disc. The reaction disc is free to spin while the drive disc is NOT engaged and when the drive disc IS engaged there is a constant velocity between the two discs.
The testbed at present has the drive disc held by an external component and so is not free to spin and it is on bearings to its shaft that is the same shaft that the reaction disc is on and the reaction disc is also on bearings.
The external constraint for the drive disc when the system is engaged is holding against a constant force from the drive disc, it is pulling on the constraint. When I accelerate the reaction disc the drive disc will slow it down and when I slow down the reaction disc the drive disc will accelerate it, these actions will bring the velocity between the two discs back to there constant state and the external constraint reacts appropriately to those changing conditions.
From this I am assuming that if I were to bring the whole system up in RPM that the relative velocity between the two discs will remain at its constant rate and that the drive disc will still be applying its constant force against whatever it is connected to, aka a motor shaft that is spinning the whole system up to some RPM and as such it would be supplying that shaft with a torque which should then reduce the input from the motor.
The system as it is consumes a lot of energy in the form of work done to both create and maintain the velocity between the two discs, right now most of that energy is dissipated as heat. In other words I am dumping electrical energy into my system (approx. 9W) and in the process of converting that energy into heat the system is creating a constant force, not that this is a heat engine, so far this appears to be a one way trip for the input electrical energy.
As time permits I will build the setup needed to mount all this on a motor and test for a drop in input while the system is engaged and see if that drop maintains itself over time. This will be to make sure that it is not a storage and usage of momentum and is a constant.

this is interesting.
This is a single unit that I simplified a more complex system down to. I was looking to make sure I understood where some spikes were coming from and where and when the energy transfers were happening. Then I made a change to some of the settings and this is what I got.
The question is: Where is all the energy going?

I have made some mods to my printer,, nothing big there.
What I just noticed is interesting to those whom use PLA.
What I have been using as a glue is DAP Rapid Fuse all purpose adhesive. It works fairly well for general gluing of parts but I just used some isopropyl alcohol to clean up the excess glue around a bearing,, I was not so happy with the fit of the bearing as far as alignment goes,, I tried to tweak it a little bit and nothing really moved but about 1 minute after I cleaned up the excess I tried again but this time the plastic and glue all acted kind of like a liquid and allowed me to reposition the bearing alignment so that it is much better.

I have in simulation a mechanical gain device. https://www.amazon.com/Plastic-Clackers-Klakkers-Makers-Favors/dp/B003415LOMhttps://en.wikipedia.org/wiki/ClackersThis toy can be very inspirational,, as well as a Newtons cradle since they are basically the same thing. I started with a basic change to the toy. This does not include any of the other stuff and is only a change to start with. This simple mod can itself be "tweaked" and change the behavior of the system. I would also point out that going from this simple starting point I supplied numbers from the sim interacting with the whole system in at least 2 different ways. What I am trying to point out is that I might of found a method but it is in no way the only method and is most likely not even the best method. <TIC> Those that are skilled in the production of mechanical gain devices might be able to infer what all the missing parts are and how they interact

Strange thought.
If I have a round tank of water and a plunger in the center and I run the plunger as such that I create a standing wave.
If the sides of the tank can move, make the diameter larger or smaller,, then as this standing wave pushes on the sides they move out lowering the water level so the plunger moves down to accommodate.
The frequency of the plunger would also need to change but the effect of a standing wave stays constant.
As the tank grows in diameter the waves would change and I think the standing wave would get shorter and then the pressure on the sides of the tank would get smaller but the surface area they are pushing on gets larger due to the increase in diameter.
In essence then the tank has stored the change in frequency,, if it is a resonant system and you are creating a standing wave the input energy stays the same but the frequency changes and the resonant growth is zero so the cost does not increase either,, meaning if there were no other losses the input cost would only be the increase in frequency and the resonant relationship would give back the energy costs to drive the system so the input then would be the same as if you just expanded the diameter,, so it is like you push the water down and expand 2 steps and the water gives back one step and then your next push is 2 steps,,
I know it is stupid,, but you have just made a resonant system that has a changing frequency,,, and as the frequency goes up the input cost per cycle goes down,, less push distance per stroke, less return distance,, blah blah blah,,

While playing with my testbeds I had a thought
Why not combine an electrostatic motor with a generator?
An electrostatic motor is a variable capacitor,, so if you made it very large and then combined that with a high voltage induction coil\PM generator,,
So the motor plates are connected to the coil so that when the PM is far away the plates have very little overlap, low capacitance, then as the PM moves towards the coil core the plates also move to a higher overlap, higher capacitance, then when the plates are at full overlap and the PM is over the core you dump the charge out of the plates.
The low capacitance will limit the flow of charge thus reduce the amp-turns from the coil, the plates will maintain a voltage between them and the coil will fill in the charge needed as they move to a higher overlap or higher capacitance, also the plates will attract,, and so as they charge up they will offset some of the counter force from induction presented by the coil to the PM.

So far the results from the spiral generator are going slow but in a good direction.
I have had test results that indicate that the counter force is due to the amps moving through the coils and that I can control things as needed to meet my concept.
I am changing things as I go along to try and keep the build simple and make the best choices of compromise so that even this very testbed demonstrates my concept,, even if this exact one has to many frictional losses and such to self run.
After I have finished with this setup I will move on to my next version which should work much better and have much fewer losses but may be more "complicated" to build and setup.

I have totally changed the rotor design.
I realized that the level of complexity in adjusting the rotor the way I was doing it made it very difficult to "tune" to the desired effect,, so I changed it into a much more simple design.

Due to the abuse of the TOS by a few people I have decided to take this site down from public view and make it mainly a members only site.
I was trying to be open and sharing in the hopes of making a good change to this world that we live in, a world we must all share.
It is very hard to share when a few choose to abuse for their own desires without thought or consideration of others.

Simple Coiled Rotary Entrained Water Device. Archimedes,, but I found that what I discovered was something that has been discovered many times,, many many times 2 versions

Dual Rotor Useless Motor,,
I needed to waste some time so I built this.
It has no case reaction whether you are spinning it up or down unless you put some kind of resistance on only one rotor.

I built this because I could not find one

I built this one to make a slightly different style of motor.
