Space Elevator

Can i have floor 32,000 please?…

It seems Japan have got the ball rolling to create a space elevator. For those who don’t know what this is, it is an elevator… INTO SPACE. Great news for affordable star-seeing and even could be good news for space travel as we know it.

The project will be undertaken by the Obayashi Corp from Tokyo and will be built using Carbon Nanotubes which are twenty times stronger than steel. The elevator will be going up a quarter of the way to the moon which is approximately 96,000 kilometers up. Awesome.

I wonder how much it would be to take a ride. Anyway they want to finish the project by 2050 so there is still time to dream yet.

It may be possible to travel to space in an elevator as early as 2050, a major construction company has announced.
Obayashi Corp., headquartered in Tokyo, on Monday unveiled a project
to build a gigantic elevator that would transport passengers to a
station 36,000 kilometers above the Earth.
For the envisaged project, the company would utilize carbon
nanotubes, which are 20 times stronger than steel, to produce cables for
the space elevator.
The idea of space elevators has been described in several
science-fiction novels. Obayashi, however, believes it is possible to
construct one in the real world thanks to carbon nanotubes, which were
invented in the 1990s, the company said.
Some other organizations have also been studying the development of
space elevators, such as the U.S. National Aeronautics and Space
In Obayashi’s project, a cable would be stretched up to 96,000
kilometers, or about one-fourth of the distance between the Earth and
the moon. One end of the cable would be anchored at a spaceport on the
ground, while the other would be fitted with a counterweight.
The terminal station would house laboratories and living space. The
car could carry up to 30 people to the station at 200 kilometers per
hour, which would mean a 7-1/2 day trip to reach the station. Magnetic
linear motors are one possible means of propulsion for the car,
according to Obayashi.
Solar power generation facilities would also be set up around the
terminal station to transmit power to the ground, the company added.
Whether carbon nanotubes can be mass-produced economically enough
and whether various organizations from around the world can work
together are two key issues facing the development of the space
elevator, according to the company.
“At this moment, we cannot estimate the cost for the project,” an
Obayashi official said. “However, we’ll try to make steady progress so
that it won’t end just up as simply a dream.”
