Solar-powered autonomous UAV AtlantikSolar has broken the world endurance record for UAVs under 50kg — by flying continuously for 81 hours. It is also the second longest UAV flight ever, behind Airbus Space’s 53kg Zephyr 7. “We had to be extremely energy efficient, as we wanted to fly though the night, so we developed large and efficient batteries that supply that energy while flying in the darkness,” says Philipp Oettershagen, 28, one of the engineers behind AtlantikSolar.
