A team took home a $900,000 prize for work related to the space elevator. LaserMotive's device used a ground based laser to provide power to the climbing vehicle. Their device was able climb up a 2,950ft cable suspended below a helicopter in 3 mins and 48 seconds. LaserMotive's laser based power used photovoltaic cells to convert the laser energy into power that can be used by remote or inaccessible machines.
Two other teams also entered the competition, but did not succeed in climbing to the top of the cable, KC Space Pirates of Kansas City, Mo., and the University of Saskatchewan's Space Design Team.
