Starting with a toy...

......we can evolve it into a self rotating variable leverage , due to gravity fall and inertia , if:


   -we add a rotation restriction for the small stick , so to play variable arm , and "tumble" the torque difference on the same side of the fulcrum


   -we build , the same shape , but with an appropriate (big) size , so to replace the power supply (electric battery potential/current flow  with gravity potential/gravity "fall" of unbalance ).

   Hi  !
Probably,,,"Thor's Hammers" , at :    www.youtube.com/watch?v=vh2a4a6JPM8


The general idea is a continuous gravity unbalance.


You can play it with hammers , pendulums ,or any other masses...if you compose a sensitive unbalance due to gravity , inertia ...and an additional input (wind,.....).
