Where does the energy come from to lift the chain inches higher than the lip on the beaker?

It is caused by velocity.
Negative Velocity to be exact.

The weight attached to the bottom of the chain stops falling, but the velocity continues then causes the negative velocity to go back up the chain. :)

------------------------

Can velocity be negative?
Yes, velocity can be negative. Velocity is directional speed, so if the object is moving opposite to the direction defined as the positive direction, it will be negative. Two objects with equal but opposite velocities have the same speed, but are just moving in opposite directions.
