Inventors rolled out this prototype of a solar-powered aircraft today. The Solar Impulse will fly for the first time in December and make a 36-hour flight in 2010. And in 2012, a larger verison will fly around the world.

Solar Impulse is the Swiss bid to make the first Solar-powered flight around the world. The prototype is an ultralight single-seater with the wingspan of an Airbus A380, with four sun-fuelled electric motors. According to Solar Impulse co-founder Andre Borschberg, it's lighter and better performing than comparable gliders.

The big challenge will come in Spring 2010, when the solar-powered craft's 36-hour flight will include flying all through the night. Images by AFP/Getty. [AFP]
