Bertrand Piccard is piloting the sun-powered plane, ‘Solar Impulse,’ across America in legs. This video is of his flight from California up to San Francisco and then down to Phoenix, AZ this weekend. He used only a third of his battery power on this leg. Airplanes are currently a source of carbon pollution, contributing to climate change (though they pale in importance in this regard before automobiles, trucks, and coal plants). Sun-powered flight is the future, and Piccard is demonstrating that the future is here.
The next leg will be flown next week, from Phoenix to Dallas.
