Until now, architects have had to design around the elevator shafts, which can comprise 40 percent of a building's core. Multi could allow them to install elevators almost anywhere, including the perimeter. Strong magnets on every Multi car work with a magnetized coil running along the elevator hoistway’s guide rails to make the cars float. Turning these coils on and off creates magnetic fields strong enough to pull the car in various directions.

After three years of work, ThyssenKrupp, a company synonymous with elevators, is testing the Multi in a German tower and finalizing the safety certification. Zooming up, down, left, right, and diagonally the new elevator was just sold to a residential building under construction in Berlin, and is expected to be sold to other developers soon.

"Multi moves to-and-fro through exchangers, which you can think of as sophisticated railway switches that guide the cars. Bearings called "slings" mounted to every elevator car allow it to change direction—say, move to the left, or even go diagonally—while keeping the car level with the ground. “The cabin never moves during an exchange,” company CEO Patrick Bass says.

Designed to move 1,000 to 1,400 feet per minute, far slower than the 1,968 fpm experienced in Dubai’s Burj Khalifa, the new elevator prioritizes volume over speed. (Speeds over 2,000 feet per minute lead to ear problems and nausea.) Free of the cable...
