The question is not so much how to reduce friction, rolling friction indeed does that, and this Rolamite idea is also very similar to a capstan. What I have shared so far shows that friction forces can nearly cancel each other out (using newtons third law and some basic rigid body dynamics) while generating heat/sound/electricity. But the system still has a tiny force component that decelerates it even if it can be considered 'overunity'. I don't want to deal with critiques that would immediately call such a design and setup fake which the internet has made a good job of in pushing countless fake videos of 'free energy' across the last decade. However it would be much more interesting to design a system that accelerates under friction without needing to extract its power and loop it back through an external motor. Such a simple setup would instantly shut any criticism down. It might be obvious but I am currently blinded to the obvious.
