Homework Statement



The coursework I'm doing is about the efficiency of elevators. It's simple enough, but I have to outline some points in my coursework summary and there's nothing relevant to them on the internet.

The Attempt at a Solution



One of the questions is "Outline the problems that need to be overcome when installing elevators in very tall skyscrapers"

There's no resources i can refer to in books or on the internet. I'm really not sure what they're looking for.

Problems with tall elevators:

-cable weight becomes a problem
-cable elasticity becomes a problem
-acceleration vs speed
-wind (pressure difference between ground and top floor will make a lot of it if not sealed)
-too many buttons for me
