This is unbelievable for me but this is true. According to Michael Laine the real critical test was on making a string strong enough. He said that the cable they made was rock solid.

This effort was considered a giant leap forward for scientists who are developing the world’s first space elevator.

According to the studies done by the United States based National Aeronautics space administration(NHSA), a space elevator would reduced the costs of sending cargo up into space from US$2,000 per pound down to $400 per pound. This cost reduction would have a great effect based on research, such a telecommunication, energy and pharmaceutical.

Using an outer space elevator instead of rockets would also be safer, easier, and gentler on fragile cargos such as electronics. Having a platform up in space can also provide room for large solar panels, more communication, cameras and hopefully, even people.

A space elevator would need a fixed lined, or cord that stretches from an anchor on Earth to station out in space, the station acts like a counter weight forever held above the planet by the antifungal force from the earth’s rotation.

The cord or shaft will be a carbon nano tube composite ribbon stretching around 99,779 kilometers up into space. The ground floor (anchor) will be a platform anchor in the sea, the elevator itself will be made up of robotic lifters that can climb up and down the ribbon at dizzying speeds without jarring its load, and the top floor will be space platform that also serves as a counter weight that will hold the whole thing upright. Gravity at one end and centripetal acceleration at the other end, will keep the space elevator from falling down on it.

So far so good the physics was the easy part. Science fiction writers had known all along that a space elevator would be possible in theory. The problem was the making of a string using a material strong enough to resist he incredible forces that the space elevator will go through.

But, their problem was solved in the 1990′s.When Carbon were discovered. Carbon nano tubes are many times stronger than steel. And now that carbon nano tubes are out of the lab and commercially manufactured, the few pieces of the space elevator are finally falling into place.
