On the one hand, true. On the other hand, bollocks.

Escovator

Escalators for Elevators

Escalators for 1 or 2 floors is ok, but for several floors, its impractical. So lets design one for several floors.. lets get a long long conveyor belt to move vertically up. Obviously it will move down when seen from the other direction. Lets attach buckets or rather elevator cabs to this moving belt, and they start moving up too (down when seen from the other side), so when our elevator cab gets to the top floor, let is go around over the belt to the other side so that it can go down. when the desired floor is reached, the cab detaches from the belt and slides onto a landing platform, without having the belt to stop (also applicable when the cab attaches to the belt to go down).. Passengers can press the botton to select their floor, in other words, which floor the elevator cab has to detach from the escalator. something similar to the Paternster lifts only difference is that the belt is continous and instead of people, the whole elevator cab rides the belt. Sort of a giant wheel (conveyor) of elevators.. inside a building. hey the elevators on the other side of the belt also act as counterweights...==> reduces power consumption

       This is already exactly how a paternoster works. (Yes, the open cab rides the belt, not just the people).

       A paterwhat?   

       Goodness. Such a name.

       I'd agree that it's widely known to exist. Weird things they are, too - I've never dared ride one, for fear of what happens if you're still in the car at the top. I'm told it's safe, but I've horrible visions of being mangled or upended or something.

       it said in the link that it stays upright even as it goes down the other side

       [jutta] The difference here is that the occupied cab detaches/attaches to the belt instead of riders stepping off and on moving cabs, increasing safety.

       Fair enough, thanks for explaining.
