Solar Impulse, an aircraft powered only by solar power, prepares for its inaugural international flight. Previously, the single seated prototype, which has the wingspan of a Boeing 777, made history when it became the first solar powered plane of its type to fly 24 hours on solar power alone. Some 11,600 solar cells, situated on the wings, charge lithium batteries, which, in turn, power the engines.
