A group of students in Denmark developed a drone capable of recharging from high-voltage power lines by using energy from their magnetic field. This was reported by Mario Nawfal, founder of IBC Group, Froothie, WeAreGrowthHackers and Optimum. The device is equipped with sensors and cameras to locate the lines when the battery level drops. "It doesn't plug in like your phone — it literally siphons energy from the magnetic field around the wires. So next time you see a drone diving toward a cable, don't panic — it's just 'filling the tank'," Nawfal noted.
