>Lifts are the disruptive technology. They make energetically efficient cities possible and cheap.
Are lifts really as efficient as escalators? An escalator is constantly moving (unless it's malfunctioning), so there is no wait to continue moving. An elevator on the other hand is not. Maybe it depends on the number of floors? I can see an elevator being faster going from ground to floor 40 rather than zig zagging floors from ground to 40. Does anybody use "express" escalators that skip floors allowing for faster transit to higher floors?
