A student at the Massachusetts Institute of Technology is developing a system in which an unmanned aerial vehicle (UAV) can perch on a power line to recharge its battery.
PhD candidate Joseph Moore hopes to equip UAVs with magnetometers so that the aircraft can identify the magnetic fields created by power lines, according to an article by Business Insider.
Pending some number crunching to further develop the software needed to make a drone perch like a bird, Moore's system can potentially allow UAVs to fly unlimited distances, as long as power lines are readily available.
In a demonstration, the system was able to direct a hand-thrown glider within centimeters of a mock wire.
