UAV Helicopter Flies 12 Hours Charged By Laser 83

garymortimer writes "LaserMotive (who last year won $900,000 in the NASA Power Beaming Challenge, one of the levels of the 'Space Elevator Games') have teamed up with Germany's Ascending Technologies to create an indoor flight record for electrically powered multicopters. The flight took place at the Future of Flight Aviation Center in Mukilteo, WA. LaserMotive is a Seattle-based company developing laser power beaming systems to transmit electricity without wires, for applications where wires are either cost prohibitive or physically impractical."
