     It can be a starting point,to think and test a gravity motor.

     All that we need:

       -to make it bigger (to "release" the gravity power).

       -to  limit the motion of small stick (180 degrees),so to get easy ,a "small arm-great arm" switch.

       -to attempt self-acting (continuous rotation of the big stick,hanging then self-tumbling of the small stick ),due to the fact that, the torque difference is on the same side of the fulcrum.

      Before to make a test,it's better to hope than to lose hope...
