The elevator was invented over 160 years ago, and engineering firm ThyssenKrupp evidently thinks it’s time to shake things up a bit. They’ve designed the MULTI: a rope-less horizontal-vertical system that’s drawn comparisons to Willy Wonka’s crazy sideways-moving elevator. And now they’ve brought their designs from paper into the real world at an 807-foot-high test tower in Rottweil, Germany. ThyssenKrupp’s technology allows multiple elevator cabins to run in a loop – “like a metro system inside a building,” according to the firm.
