Photovoltaic panels, which convert laser light into electrical energy similar to solar panels, are seen on the bottom of the LaserMotive entry in the $2 million Space Elevator Games at the NASA Dryden Flight Research Center at Edwards Air Force Base, Calif. , Wednesday, Nov. 4, 2009. In a the test of the concept, robotic machines powered by laser beams will try to climb a cable suspended from a helicopter, on a course 900 meters (2,953 feet) high.
