Laser power beaming keeps drone fully charged
Wireless power transmission, a notion whose principles were pondered by Nikola Tesla and Arthur C. Clarke amongst others, may soon be put to practical use as a means to extend the flying time of unmanned aerial vehicles (UAVs).
A demonstration of "laser power beaming" by Lockheed Martin and LaserMotive has proved that a laser situated on the ground could act as an energy source for an operational UAV in flight, and recharge its on-board power cells.................... http://optics.org/news/3/7/31
