15 Secs: Are 'Willy Wonka' lifts possible
A German firm is proposing a lift that can move like the fictional "glass elevator" in the children's book Charlie and the Chocolate Factory.
ThyssenKrupp says its lift could potentially pick someone up in a car park and navigate the contours of a building to take them to their office floor.
It estimates it could move lifts through a lift shaft every 15 to 30 seconds.
