Breakthrough in Solar-Powered Drones: The ColumbFly Achieves Unlimited Daytime Flight

Researchers at Beihang University in Beijing have developed an ultralightweight solar-powered drone, named ColumbFly, capable of unlimited flight during daylight hours. Weighing only 4 grams, ColumbFly utilizes a solar cell to generate electricity, creating an electric field between oppositely charged plates arranged in a circle. These opposing charges act like repelling magnets, producing enough force […]
