.....namely the Kojin motor , you can watch on youtube , at :

...if we solve two problems :
-to synchronize the angular velocity
-to introduce a variable length ( draw-tube telescope...) leverage, so to keep a continuous gravity unbalance .

.....if we take a look at a similar proposal (2008) :

.....then introducing Kojin's motor simulation (2013 ):

.....with a "different" synchro rotation , but playing the same continuous gravity unbalanced leverage.

After reading this content. It made me realize many things that I never knew before. It is a very useful knowledge.
