Scientists develop 4g solar-powered drone that might fly forever
科学家开发了一种4克重的太阳能无人机，它可能会永远飞行
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.
中国研究人员在无人机技术方面取得了显著进展，开发了一种名为CoulombFly的太阳能模型。这款空中机器人仅重4克，由微型太阳能板供电。CoulombFly体型小巧，与蜂鸟一样大，迄今为止仅在自然阳光条件下进行了一小时的测试。尽管测试时间有限，科学家们相信他们的方法可以引领创造出昆虫大小的无人机，能够无限期地在空中飞行。
