    Had an interesting discussion with a bemused top manager of a transportation provider about escalators on 24/7

    After I wrote to T5 about this they now mostly only run escalators on demand

    But for up escalators all the work of lifting people is at an energy cost, if there were down escalators (not the case in question) almost all the energy could be reclaimed.

    But if there were more down escalators than up ones then energy could be generated free of charge form the general public :swingin:

    I think this idea could have 'legs'

    So how do the extra people get up to the top floor to use the extra down escalators? Surely there needs to be equilibrium, where the number of people going up = the number going down?

    Maybe escalators should get replaced with zero energy counterbalanced lifts, where the people going up are moved by the weight of the people going down...............

    My idea is that they walk up some stairs like I do, (I try to never use escalators or lifts)

    two down escalators for every one up one?

    Instead of escalators, down lifts only, operated by a braked system that generates enough electricity to lift the (empty) lift back to the top again.

    Also, brilliant idea this, the 'up' stairs actually drop back a rise from the weight of people going up to generate enough electricity to supplement the return of the lifts. Would mean people would have to run up the stairs to make any headway, but hey, think of the savings on the NHS with a population really fit again.

    What? :neutral:

    Would need to be very low friction, which could make it a very rapid decent.
    I was over 40 before I ran down an Up escalator :bigsmile:

    Wimp! You have to run up the down escalator for it to be worth bragging about.

    No what you need is more people wanting to go down than up. Your suggestion only works if having fewer up escalators encourages people to use the stairs.

    Since people usually gain weight on holiday perhaps best put arrivals on the top floor :-)

    Food poisoning made me loose weight, and that was a trip to Devon

    That's the answer then. Anyone with a BMI >30 should only be allowed to buy food in a special cordoned-off area selling only food that has gone past its sell-by date.

    (And how did you manage to correlate weight loss with a trip to Devon? :confused:)

    How about all the up people walk up say six normal steps first then take the escalator? would that make it balance?
