What is the Solar Impulse?

A Swiss team of engineers and pilots has developed the Solar Impulse, a spindly airplane that soars on the power of sunshine. Solar panels line nearly every inch of the plane’s passenger-jet-size wingspan, absorbing energy from the sun and storing it in lightweight batteries that power four electric propellers. The plane completed its first overnight flight in 2010, proving that it could harness enough solar power during the day to keep it aloft through the night. Don’t plan to book a solar flight anytime soon, though – the Solar Impulse is strictly a one-seater aircraft, built to be as lightweight at possible. Even the pilot can’t exceed 187 pounds (85 kg).
