Title: Centrifugal overunity...

Anyway , inertia is the first law of mechanics...having so physical reality...and , why not ...not known,strange but helpful,practical effects ?!

Your idea is excellent and with the 2 counter rotating you eliminate gravity as a loss.
Then it is reduced to friction vs centrifugal forces. I did something similar to this but
with a single rotating weight and measured the tilt to the left or right but did not find
that it had OU. However your idea is better. I drove mine with a weight on a string
so that I could measure the input and output visually (mass x distance) so that no
instrument could be accused of being wrong.

I will work on this but have several weeks of other priorities first ie taxes and vacation.
Best of luck.

The error made in this video is common: forces are evaluated in different mixed reference frames, some of which being not even inertial.

Here, the force Fc is evaluated in the reference frame related to the center of rotation linked to the carriage, which is not fixed, while the forces Fa and Fb are evaluated in the referential of the fixed frame. It is therefore not possible to obtain their resultant by mixing them in a simple vector addition.

It's like calculating the force that a car can exert at a certain speed on an obstacle on the road, and thinking that a passenger inside the car, therefore with a speed relative to the car that is zero, could use that force!

Only one reference frame must be chosen to do the force analysis, it is the basis of mechanics. Contrary to what is specified, Fc ≠ m.R.ω² relative to the fixed frame. Force and energy depend on the reference frame.

Hi !
The simplest manner to revel Newton's first law (inertia) is rotation...as a "key" to discover a huge physical  unknown world,yet?!
If you play a balanced rotation , we can enjoy the merry go round or can use ultracentrifuges , capable of generating acceleration as high as 1000000g...( https://en.m.wikipedia.org/wiki/Ultracentrifuge (https://en.m.wikipedia.org/wiki/Ultracentrifuge)  )
If you play an unbalanced rotation ( www.hajtech.hu/vibrator/sceltavibratoree.htm (http://www.hajtech.hu/vibrator/sceltavibratoree.htm) ) , we have a direct access to the centrifugal acceleration ...it can be rotative ( one rotating mass ) or to ways /to and fro / ( two counterotating massess ).
Our intention is to obtain a "clean" one way controllable tractive vector and to use it ...if we employ Di Bella's mechanism /1967(Apparatus for imparting motion to a body ) , but as a quadrupled synchro-arrangement .
So, if we have a "confortable", facile,manageable acceleration , then...let's go back to Newton's laws...
Maybe, to collect the "overunity " we need to rotate a certain assembly in a specific way...nothing more.

This experiment I did with an unbalanced flywheel prooves that any attemp to introduce friction or any kind of energy tapping, slows down the flywheel. It dies the very same as your video.
Look at this video, and see what you can expect from your design in your video. In short: Any attempt to take energy out of this system require energy input to sustain rotation.

I did not understand the point with the first part with the pink centrifugal thing, but I can explain why the second part doesn't work.
The blue wheels wants to roll counter clockwise due to the weights at the left side of them. This will force the green wheel to rotate clockwise.
In the video, the green wheel goes counter clockwise, but the counter clockwise torque from the surrounding blue wheels will prevent it to do so.
Also notice that the red lead weights are repeating the same altitude. That means that these weights does not gain potential or kinetic energy during a complete cycle.
So, it doesn't work.

Hi !
Take a look at : www.freepatentsonline.com/3404854.html (http://www.freepatentsonline.com/3404854.html)
It's easy to say "no"...before to read...
Di Bella's proposal is a double rotated (accelerated) mass with a Viviani trajectory.
With four syncro rotating vectors , we can obtain a linear pulsatory one way translational vector...
