A Seattle team has won a $900,000 prize in a NASA-supported competition to develop the concept of a space elevator. The winning team's robotic machine charged up nearly 3,000 feet of cable dangling from a helicopter. Powered by a ground-based laser pointed up at the machine's photo voltaic cells, which convert the light into electricity, the LaserMotive completed one of its ascents in just three minutes and 48 seconds "“ fast enough to secure the second place prize. The three-day...
