around the world with no fuel Solar Impulse was not built to carry passengers, but to convey messages. An adventure that shows change is possible. The future can be written in . A challenge we can all take part in together. the zero fuEL around the world

A bold challenge and an incredible adventure attempting the first solar flight around the world and laying down a benchmark for the future.

INSPIRING THE WORLD POWERED BY THE SUN 35,000 KM 25 FLIGHT DAYS 500 FLYING HOURS OVER 5 MONTHS exploration an EPIC to change in s ta g e the world s A wild idea to fly an airplane day and night, using no fuel, only powered by the sun. An inspiring journey to show that it is possible to save our planet by using clean technologies.
