The one-seater solar aircraft is similar in size to a large plane, but it only weighs as much as a regular car. It is powered by 12,000 solar cells that cover the plane’s wings. They absorb the sun’s energy, and in turn charge batteries that power the 10-horsepower motors that spin the plane’s four propellers.
The Solar Impulse proved itself with last summer when it conducted a 26 hour, 10 minute, 19 second flight over Switzerland. Since then it has also flown between Geneva and Zurich in commercial airspace. Click here to see Solar Impulse wowing the crowds at the Paris Air Show.
