Thyssenkrupp MULTI

What if elevators could move sideways, instead of just up and down? It’s a question straight out of Charlie and the Chocolate Factory, and Germany-based Thyssenkrupp has a real-life answer: MULTI, a system of elevators that ditches old-school pulleys for the same magnetic levitation tech that enables high-speed trains. The elevator cars can travel in multiple directions and even pass each other within a shaft—features that could not only reduce wait times, but also fundamentally“change how buildings are constructed,”says Andreas Schierenbeck,CEO of Thyssenkrupp Elevator. (Think horizontal offshoots of straight, vertical towers.) Following a successful test this year, the first MULTI is set to debut in Berlin by 2021. —Julia Zorthian
