(Phys.org) —Elevator tech has hit a wall, or at least the wrong floor of the person's destination, with limitations that are unable to accommodate the world's tallest buildings. As buildings rise, logistical demands rise with them. The weight of steel cable does not make it easy for elevators to zoom straight to the top. Instead, they reach a limit and that is it. For example, people going up in a 828-metre-high tower, such as in Dubai, need to switch lifts once they have reached the top mark in one elevator, going over for another. Elevators today are also subject to severe strains such as building sway, potentially knocking them out of service under especially poor weather conditions.
