来自瑞士的“阳光动力2号”本周一在阿联酋首都阿布扎比出发，展开为期5个月左右的环球之旅。全程将“不使用一滴石油”。“阳光动力2号”将由“阳光动力”项目的联合发起人贝特兰德·皮卡德和安德烈·博尔施伯格轮流驾驶。

A Swiss solar-powered plane took off from Abu Dhabi early Monday, marking the start of the first attempt to fly around the world without a drop of fuel.

Solar Impulse founder André Borschberg was at the controls of the single-seater when it took off from the Al Bateen Executive Airport. Borschberg will trade off piloting with Solar Impulse co-founder Bertrand Piccard during stop-overs on a journey that will take months to complete.

The Swiss pilots say their aim is to create awareness about replacing "old polluting technologies with clean and efficient technologies."
