Science fiction becomes reality. The Japanese company Obayashi has declared its readiness to build the space functioning elevator by 2050. This idea, if successful, will revolutionize space travel and revolutionize the world economy.
ABC News Agency reported that the Japanese construction giant Obayashi is working on the space elevator,a total length 96,000 kilometers into space. Robotic cars for magnetic linear motors will deliver people and cargo to the orbiting space station. Such transportation will be cheaper than using modern missiles. In this, in one direction way only takes a week.
The concept of a space elevator is as follows. Massive platform in the ocean holds one end of the wire is of high strength, and the second – is attached to the space station. Tightrope moves specially designed cabinet, which can deliver the goods, astronauts or, say, space tourists.
As a material for cable Obayashi is considering carbon nanotubes, which is ten times stronger than steel. But the problem is that now the length of the nanotubes is limited to about 3 cm, whereas the need for a space elevator rope total length of 96 000 km. Expected, that overcome the current difficulties possible will tentatively in 2030s, and then begin the practical implementation of the concept of a space elevator. Now the cost of O 1 kg of cargo space is on average $ 22 thousand. After the elevator, this figure drops to $ 200. Obayashi is considering the possibility of creating special tourist cabins, designed to carry up to 30 passengers. By the way, way into orbit on the rope of carbon nanotubes will take seven days, so you have to make the necessary life support systems, supply of food and water.
