I was going to call you a retard, but you just solved the problem: there is no net force acting on the tube in that case since the condition before and after is the same: so no energy generation.

In the case of the balls you actually have the same: at some time t the system will be in the same conformation as at time zero. So in the time span from t0 to t the system will not change energy and no electricity will be generated.
