NASA plans to build a prototype of space elevator that can lift up from the Earth to the space. According to CNN.com, NASA offered up for anyone who can build a prototype of an elevator able to crawl up a kilometer-high tether while hauling a heavy payload and this week in the Mojave Desert, three teams of engineers are competing for $2 million.Most models for an elevator into space which is presented by those scientists involve attaching a cable from a satellite, space station or other counterweight to a base on Earth's surface. Scientists say inertia would keep the cable tight enough to allow an elevator to climb it.
The inspiration of this idea based on some science fiction story such as on 1979 by Clarke on his Novel titled "The Fountains of Paradise" where he writes about a scientist battling technological, political and ethical difficulties involved in creating a space elevator.
In the years that followed, Clarke, who died last year, remained an outspoken advocate for researching and funding the elevator. However, the scientists say that currently not available strong enough material o make the cables that will support heavy loads of passengers or cargo into orbit. According to NASA research, the space elevator cable would need to be about 22,000 miles long. To make it real, a super-light material is needed but must be at least 25 times stronger than today’s material available.
With all the obstacles, can this mega-project with high technology adapted be realized in short time? Do you think it’s real or science fiction only?

wah ga bawa kamus he..he..
ehm its good make me know more to get info like this ,dah saya follow sob kalo mau follow bali ya..thnxs n good luck
how many matterial will they use to make an elevator to space. i can't imagine it!
wuiiihhh keren kalau beneran ada tuch...... tapi masak iya bisa jadi kenyataan..... kayaknya science fiction dech.
