Cosmic elevators we have encountered so far in sci-fi novels, however, the Japanese company Obayashi, is going to move this remarkable structure to the real world and plan to build it.
Construction of the space elevator has been mentioned for many years, but implementation of this project is not possible at present due to lack of appropriate technology. However, if such a thing could be created, it would bring many benefits, reducing the cost of transporting goods and people to orbit, while allowing for the construction of orbital shipyards from which space ships would travel.
So far, the idea has remained only in the sphere of dreams, but the Japanese company Obayashi wants to realize this venture and believes it will be possible to do so by 2050. Tokyo Skytree says the total length of the elevator will be 96,000 km, and at the other end, a counterweight will be installed to keep the cable under proper stress. However, at the height of 36,000 km would be the end station.
The system would be operated by robotic wagon powered by magnetic linear motors capable of carrying up to 30 people. However, the journey to orbit would last about 7 days, so this car would actually have to be a well-equipped hotel to provide passengers with the right level of comfort.
Yoji Ishikawa, head of Obayashi's scientific department, says that the project would be possible thanks to carbon nanotechnology that would allow fibers to be about 100 times stronger than steel cables. At the moment, however, the construction of such a long cable is not possible because in the laboratories it is possible to create nanotubes of only 3 cm in length. Ishikawa, however, believes that it should be possible by 2030.…
