  • Do escalators going down put electricity back into the grid?

    Where I work there's a station with lots of escalators to move people up and down as they use the station.

    In the morning this means loads of people going up at the same time, which must use loads of electricity.

    It got me thinking... in the afternoon when there are more people going down, do the escalators convert the downward mass into electricity and feed it back into the power grid?
