The Zhangjiajie National Forest Park, is protected by UNESCO so the construction of the Bailong Elevator have been a subject of debate.
The Bailong Elevator, also known as the Hundred Dragons Elevator, holds the Guinness World Records for the tallest outdoor lift in the world since 2015 but it seems that it will not be in the Guinness book for long time. The Canadian space firm has patented a 20 km tall (12.4 miles) space elevator, named the ThothX Tower.
Thoth’s Elevator will be twenty times higher than the world’s current tallest building, Dubai’s Burj Khalifa.
ThothX Tower is expected to reduce the cost of transporting equipment and personnel to space stations. The elevator’s roof will have a runway from which spacecraft could be launched.
