Solar Impulse Achieves First Fully Solar-powered Flight

Swiss-based Solar Impulse has achieved the maiden voyage of its solar-powered aircraft. From here on, the question will no longer be whether solar-powered air travel is possible, but how efficient are the technologies allowing it to compete with combustion-powered air travel.

The craft in this video is extremely lightweight and cannot carry passengers, but now that the combination of technologies necessary to achieve solar-powered flight has been consolidated, researchers across the world can more clearly see what needs to take place to make such a fueling system viable for safe, long-distance collective human transport.
