The Solar Impulse 2, a Swiss-engineered aircraft, made history by flying around the world using only solar power—no fuel, no emissions, and purely clean energy. Covering over 40,000 km, the mission began in 2015 and concluded in 2016, making 17 stops across 4 continents.
With a wingspan wider than a Boeing 747 but lighter than a car, it housed over 17,000 solar cells on its wings and fuselage. The aircraft could fly day and night, storing solar energy in onboard batteries for nighttime propulsion.
This mission wasn’t about speed or convenience—it was a symbol of sustainable innovation. Solar Impulse 2 proved that renewable energy isn’t a dream for the future—it can already carry us around the world.
