Using traditional steel lifting cables, elevators can’t go farther
than 500 meters (1,640 ft) in one vertical run. Any higher, and the
weight of all the cable required is simply too much. Currently in the
world's few buildings that are over 500 meters tall, passengers must
transfer from one elevator line to another, part way up. Thanks to a
new lightweight material known as UltraRope, however, elevators should
now be able to travel up to one kilometer (3,281 ft) continuously.



Another step towards the space elevator.
