Elevators planned for a Chinese skyscraper will be the fastest in the world, traveling at 44.7mph. How fast is that, in building terms? Well, the two Hitachi elevators will cover 95 floors in 43 seconds, Businessweek reports. They'll be housed in the 1,738-foot Guangzhou CTF Finance Center, which is due to open in 2016. According to Hitachi, passengers will have a "comfortable ride."
But "when you're traveling that distance, you're going to get pressures on your ears changing," an expert tells the BBC. Hitachi says it will adjust air pressure inside the elevator cars accordingly. Meanwhile, "active guide rollers" will deal with vibration and any "minute warping in the guide rails," the company adds. Brakes will be able to withstand high temperatures. Currently, the world's fastest elevators are in Taiwan's Taipei 101 building; they move at 37.7mph. (China is also home to the world's second tallest building—and two daredevils recently scaled it.)
