This tiny solar-powered flyer weighs less than a paper plane
Briefly

Researchers created CoulombFly, a solar-powered MAV with an electro-static motor and light solar panels to provide untethered flight, solving endurance limitations in MAVs.
MAVs under 10 grams face a 10-minute flying limit, but CoulombFly could expand their applications in environmental monitoring and search and rescue missions.
