The prototype for a solar-powered aircraft has been unveiled by two Swiss adventurers and they hope it would fly around the globe in 2011. The project has been aptly christened Solar Impulse. The solar cells have been integrated into the wings, which will collect sunlight and it will be converted into energy. This energy will be used to power the electric motors of the plane. This plane would definitely be a green marvel, and the technology would be one great step towards reducing our reliance on aviation fuel .
