The elevator has not changed since the 1800's when it was a rope pulley system. The Elevator is still on ropes, although now it's steel ropes and pulleys. With cities having little space to build and more and more people moving in to the city, builders are thinking of how to utilize the space. Change the buildings? Or change the elevator?

In this video you can see how changing the elevator can change the way buildings are made, how people ride the elevator, and how more people can get to more places in the building faster.

I've also included a video showing how an elevator works, so you can understand the difference.
