  The elevator of the future may be just over the horizon thanks to German company ThyssenKrupp.The firm has invented a cable-free elevator (called MULTI) that can go up and down like traditional lifts but the magnetic motors allow it to go side-to-side too.The designers predict that this technology could incrase the carrying capacity of existing architecture by as much as 50%.Plus it looks really neat.

  ThyssenKrupp plans to use light-weight materials to build its elevator ears of the future and the lack of a cable winch(钢缆绞车)will reduce weight as well.The ears wouldn't just move up and down as they do now but would instead go in a circle that allows more cars to slip in fight behind the next.The result is that you might only have to wait 10seconds for the next one to arrive rather than wait for the one you just missed to come back down.

  The technology backing ThyssenKrupp's MULTI elevator is very similar to magnetic levitation(磁悬浮)systems used in high-speed trains.Each car has two magnetic motors-one for vertical movement and another for horizontal.This system can also deliver power to the car's internal lighting and electronics without using wires.

  A traditional cable driven elevator has mechanical components that can hold the car in place in the event of a power-off.ThyssenKrupp didn't go into detail about safety measures in its announcement but it's safe to say the magnetic levitation elevator will have some sort of system to hold it in place if the lights go out.ThyssenKrupp is working on a test tower that will be used to develop the MULTI into a real elevator technology.This should be up and running by 2016but it will probably take at least a few more years before you get to climb inside a magnetic elevator car.
