Japan Will Have a Space Elevator by 2050
The company plans to use carbon nanontubes, which are 20 times stronger than steel, to produce the cables required for the elevator. Those cables will be stretched to a counterweight 96,000 kilometers above our planet, about one-fourth of the distance between the Earth and the moon.
The terminal station, 36,000 kilometers above Earth, will be reached by cars that can carry 30 people and travel at 200 kilometers per hour. An Obayashi official said:
"At this moment, we cannot estimate the cost for the project. However, we'll try to make steady progress so that it won't end just up as simply a dream."
