In 2015, an exclusive patent
for the creation of an elevator to space received a Canadian company Thoth
Technology Inc.. The tower ThothX Tower will be 20
kilometers - is almost 25 times higher than the tallest building in the world,
the skyscraper "Burj Khalifa" in the United Arab Emirates. The upper
area of the tower will host the start and refueling of spacecraft; they would not
require energy-intensive run vertically, which will save up to 30% of the fuel.
