"A space elevator is a 65,000-mile tether upon which we can launch things into space in a slow, safe, and cheap way. And these climbers don’t even need to carry their energy as you can use solar panels to provide the energy for the climbers. All this means you need much less fuel. Everything is fully reusable, so when you have built such a system, it is easy to have daily launches. The first elevator’s climbers will travel into space at just a few hundred miles per hour — a very safe speed. Building a device which can survive the acceleration and jostling is a large part of the expense of putting things into space today. This technology will make it hundreds, and eventually thousands of times cheaper to put things, and eventually people, into space. A space elevator might sound like science fiction, but like many of the ideas of science fiction, it is a fantasy that makes economic sense. While you needn’t trust my opinion on whether a space elevator is feasible, NASA has never officially weighed in on the topic — they haven’t given it enough serious consideration. This all may sound like science fiction, but compared to the technology of the 1960s, when mankind first embarked on a trip to the moon, a space elevator is simple for our modern world to build. In fact, if you took a cellphone back to the Apollo scientists, they’d treat it like a supercomputer and have teams of engineers huddled over it 24 hours a day. With only the addition of the computing technology of one cellphone, we might have shaved a year off the date of the first moon landing. Carbon Nanotubes Nanotubes are Carbon atoms in the shape of a hexagon. Graphic created by Michael Ströck. We have every technological capability necessary to build a space elevator with one exception: carbon nanotubes (CNT). To adapt a line from Thomas Edison, a space elevator is 1% inspiration, and 99% perspiration. Carbon nanotubes are extremely strong and light, with a theoretical strength of three million kilograms per square centimeter; a bundle the size of a few hairs can lift a car. The theoretical strength of nanotubes is far greater than what we would need for our space elevator; current baseline designs specify a paper-thin, 3-foot-wide ribbon. These seemingly flimsy dimensions would be strong enough to support their own weight, and the 10-ton climbers using the elevator. The nanotubes we need for our space elevator are the perfect place to start the nanotechnology revolution because, unlike biological nanotechnology research, which uses hundreds of different atoms in extremely complicated structures, nanotubes have a trivial design. The best way to attack a big problem like nanotechnology is to first attack a small part of it, like carbon nanotubes. A “Manhattan Project” on general nanotechnology does not make sense because it is too unfocused a problem, but such an effort might make sense for nanotubes. Or, it might simply require the existing industrial expertise of a company like Intel. Intel is already experimenting with nanotubes inside computer chips because metal loses the ability to conduct electricity at very small diameters. But no one has asked them if they could build mile-long ropes." - Thomas Page

Anyone do any research on building a hill or a mountain high enough to reach "outer space"? - Sue - Friendfeed is best

Lunar space elevator http://en.wikipedia.org/wiki... It is similar in concept to the better known Earth space elevator idea (a cable suspended above Earth, with its center of gravity slightly above geostationary orbit). It would instead be constructed with its center of gravity in a stationary position above the surface of the Moon, providing a controlled means to transport people and/or materials between the surface and lunar orbit. http://www.space.com/13670-l... A new exhibit at the American Museum of Natural History will highlight some of the cutting-edge space technology in hand or under way, from a rover that looks for life on Mars to an elevator that rises into space from the moon. , 8 -15 http://what-if.xkcd.com/7/# - Thomas Page
