The key element towards bringing the “Space Elevator” dream to life is in the works.
Until now, the idea seems like a sci-fi fantasy but since the discovery of CNT by a Japanese engineer in 1991, progress towards its creation is getting faster.
Basically, a cable made from carbon nanotubes (CNTs) measuring 96,000 kilometres long will form the base of the journey’s route. CNTs were discovered by a Japanese engineer way back in 1991, and are the only material appropriate for such a feat.
The space elevator cable, which will stretch through the Earth’s atmosphere, will carry materials and people using wheeled lifts called “Climber”.

The Space Elevator Construction Concept will take place over multiple stages.

The allure is that once the space lift is built, it will be less expensive to go into space and more sustainable as there is no fuel or toxic chemical waste.
At a launch speed of 150km/h, the Climber will reach an altitude of 400km, where the International Space Station is located, in about 2.5 hours. That is almost the same as travelling between Tokyo and Osaka – the two major cities in Japan – by bullet train. Each launch will probably cost around several million yen or a few thousand dollars, according to Obayashi Corporation’s calculations.
Construction is set to start in 2025, and, if all goes to plan, we could be ‘pressing an elevator button’ to reach space by 2050.
Watch this space.
