German company ThyssenKrupp is proposing a self-propelled lift that can travel both horizontally and vertically through large buildings and skyscrapers.

The system operates without cables and uses magnetic levitation technology similar to that used on some train networks.

The proposed system is made up of multiple cabins travelling in a loop at about 5m per second (about 11 mph, 17 km/h), allowing passengers access to a lift cabin every 15 to 30 seconds.

BBC Click talked to the company's chief executive Andreas Schierenbeck about their proposals to change the way we move through tall buildings.
