Tether Challenge
Elevator:2010 was an inducement prize contest with the purpose of developing space elevator and space elevator-related technologies. Elevator:2010 organized Space_elevator_competitions, annual competitions for climbers, ribbons and power-beaming systems, and was operated by a partnership between Spaceward Foundation and the NASA Centennial Challenges. History On March 23, 2005 NASA's Centennial Challenges program announced a partnership with the Spaceward Foundation regarding Elevator:2010, to raise the amounts of monetary prizes and to get more teams involved in the competitions. The partnership was not renewed after its initial 5-year term. There were two (out of an intended seven) competitions of the NASA Centennial Challenges which fell under the Elevator:2010 banner: The Tether Challenge and the Beam Power Challenge. There were also the two original competitions. Tether Challenge This competition presented the challenge of constructing super-strong tethers, a crucial com ...

An elevator (American English) or lift (English in the Commonwealth of Nations, Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a Hoist (device), hoist, although some pump hydraulic fluid to raise a cylindrical piston like a Hydraulic jack, jack. Elevators are used in agriculture and manufacturing to lift materials. There are various types, like chain and bucket elevators, grain augers, and hay elevators. Modern buildings often have elevators to ensure accessibility, especially where Inclined plane, ramps aren't feasible. High-speed elevators are common in skyscrapers. Some elevators can even move horizontally. History Pre-industrial era The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes ( – ) built his first elevator probably in 236 BC.
