Chinese researchers have made significant strides in drone technology, with the development of a solar-powered model, named CoulombFly. This aerial robot weighs just 4gm and is powered by tiny solar panels. The CoulombFly, as small as a hummingbird, has so far only been tested under natural sunlight conditions for an hour. Despite this limited testing period, the scientists believe their approach could lead to the creation of insect-sized drones, capable of staying airborne indefinitely.
