You haven't read your theory yet, JL says....

"If, as you say, light bulbs suck up darkness and convert it to smoke which is transmitted (via wire) to a power source for recycling."

The battery is only a bulk pressurised smoke container, it is the darkness adsorbing head lights that convert the dark back into smoke that keep the whole system energised.

Didn't you get to the Lucas 101 classes?
