Space elevator wins $900,000 NASA prize

A laser-powered robotic climber has won $900,000 in a competition designed to spur technology for a future elevator to space. Building a space elevator would require anchoring a cable on the ground near Earth's equator and deploying the other end thousands of kilometres into space. The centrifugal force due to Earth's spin would keep the cable taut so that a robot could climb it and release payloads into orbit.
