THIS VERY IMPRESSIVE ( assumedly fake ) MACHINE HAS A LOT OF POTENTIAL

This very impressive   'Perpetual Motion'  machine,  in the youtube link below

could be modified at the  'points'  'A'  or  'B'  marked in the diagram below,  to function successfully.

It is claimed that that there is an  Electro-magnet  hidden at point  'A',   in the diagram below.

It may be possible to replace the hidden  Electro-magnet  at point  'A',   in the diagram below,  with some type of  Permanent-Magnet design or device (  or even with a smaller version of this actual device ).   

THE POINT COULD BE THAT COMBINING THE TWO FORCES,  GRAVITY  AND  MAGNETISM,  COULD  'BREAK THE SYMMETRY'  USUALLY PRESENT IN DEVICES RELYING ON JUST  GRAVITY  OR  MAGNETISM

YES, big YES! Not about the machine ,but I'm sure that combining magnetism and gravity will allow construction of various self-running machines.
