The Space Elevator is a fascinating concept; a way of moving materials (and possibly people) into Earth orbit without the use of rockets. A surprisingly old concept from the 19th century, I first became aware of such an idea in Arthur C. Clarke's novel "The Fountains of Paradise". Now, a Japanese company has announced their intention to have a space elevator up and running by 2050.
The Japanese construction giant Obayashi says they will build a space elevator that will reach 96,000 kilometres into space.
Robotic cars powered by magnetic linear motors will carry people and cargo to a newly-built space station, at a fraction of the cost of rockets. It will take seven days to get there.
The company said the fantasy can now become a reality because of the development of carbon nanotechnology.ABC News
