Space Elevator Test Run

(NO SOUND)  The LiftPort Space Elevator consists of a ribbon made of a very strong and very light material, carbon nanotubes, anchored to the Earth's surface with the other end reaching into space. The video shows a successful 1000 foot space elevator test climb to a tethered 10-foot diameter balloon. It was supposed to be a 1 mile climb test, but the FAA-required aviation orange paint contained acetone, which weakened the ribbon.

By making the ribbon long enough, and attaching a small satellite as counterweight, the Earth's rotation will provide enough centrifugal effect to overcome the pull of gravity and keep the ribbon taut. The Space Elevator will then provide a permanent bridge between earth and space. Elevator cars will be robotic "lifters" which will climb the ribbon to deliver cargo and eventually people to orbit or beyond.    Popular Science article: Space Elavator
