A Seattle-based team has won $900,000 in this year's Space Elevator Games, a NASA-sponsored contest to build machines powered by laser beams that can climb a cable in the sky.
The homemade cable-climber built by the LaserMotive team climbed a 3,000-foot (900-meter) tether suspended by a helicopter at a speed of 8 mph (3.7 meters per second or 13 kilometers per hour) during a Wednesday attempt.
LaserMotive's robot climber managed to get all the way up the cable four times in two days, with a best time of about 3 minutes and 48 seconds (translating to a speed of 3.9 meters per second).
The feat was the best performance yet for a miniature space elevator prototype and qualified LaserMotive to win the lower-level prize of NASA's $2 million Power Beaming Challenge this week at the Dryden Flight Research Center at Edwards Air Force Base in California's Mojave Desert. The contest requires competitors to beam power from a remote source to propel their vehicles up a quarter-inch-thick steel cable dangling from a helicopter.
The 2009 Space Elevator Games are the first in which prize money has been awarded. This year's event was "a very successful competition," said Andy Petro, director of NASA's Centennial Challenges program. "Power beaming is truly a 21st-century technology."
