The positions of each weight have exactly the same force on the wheel irrespective of which weight is where. The condition is that as long as there is a weight in the same place as there was before there cannot be any gain.
We can therefore conclude that if a wheel is out of balance and we move the weights in an "open" path for the duration of the change from one set up of weights to another identical set up of weights we will again have an out of balance wheel. We need to seek a continuously out of balanced state as opposed to trying to put a balanced state out of balance.
An "open" path is only open for 360 degrees. After that, it is closed.
An initially OB state wasn't put in that OB state by gravity. And gravity wouldn't add any overbalance to that initial state. It simply converts the initial energy.

So i had to think about this one for a minute.
In a “closed path� it is a true statement that no work is performed Only IF no additional energy is added. This is why it is important that we consider besslers wheel an open system. Any PM device must have an energy source.
We can debate on what this energy source was but iit does not change the fact that an unlimited source of energy is required.
In a "closed path" no work is performed by a conservative force. A wheel contains a closed path by definition.
IF additional external energy (or matter) is added then it's an open system.
Gravity is both an internal and external conservative force in the context of open and closed systems. IOW, no system can be completely isolated from gravity.
