The Bessler Wheel, mystery solved.

[Newton II]

The pulley does not perform any work, and if it is massless and frictionless, no work is performed on it.  That is getting away from the issue.   The total energy in the system is the sum of the GPEs of the two weights.  When the GPE of one decreases, the best that one can do with an ideal system is identically increase the GPE of the other.
 

Pulley doesnot perform any useful work adding to the action.  But what about the reactive force in the opposite direction provided by pulley?  Will it not cause any flow of energy in opposite direction?  Heat is produced by frictional force which is  µ*F  which is very less depending on type of surface whereas reaction force is -F which is exactly equal to the applied force in magnitude.

Please reread my post.  I explained the effects of any deformation of the pulley/bearings.  Energy goes into deflecting / deforming, and it comes out of the GPE.

One question from my side my friends. As toys are the key to understanding I have to understand the toys first.

Toys C, D and E are quite obvious.
B is Jacobs Ladder.
What's A??

Oh right, do not imitate it, modifications are needed.
