Originally shared by The Economist
Kone, a Finnish liftmaker, announced that it has devised a system that should be able to raise an elevator a kilometre (3,300 feet) or more. Since the effectiveness of lifts is one of the main constraints on the height of buildings, Kone’s technology could result in buildings truly worthy of the name “skyscraper” http://econ.st/196PsTk
