From SayPeople,
In order to reach the maximum speed and safety Mitsubishi has used a rope of high-intensity steel strands wrapped in plastic with its bullet-like elevator. This elevator has an additional property of “green technology” i.e. its motors have built-in converters that can regenerate electricity causing reduction in the consumption by 30%. Mitsubishi has used several mechanisms to minimize vibrations and to control air pressure.Shanghai Tower is 632 meter in height and will open in 2014.
