After the first solar night flight flying demonstration using no fuel whatsoever, Solar Impulse has opened up new prospects for energy saving and renewable energy. A way of promoting a different future.

Flying a solar impulse means pushing back the limits of the possible. For Bertrand Piccard and André Borschberg, the challenge is to fly a solar airplane around the world in five steps.
