Quick Summary

Solar Impulse is a project focused on developing and launching solar-powered airplanes capable of circumnavigating the globe. The project's goal was to create aircraft that could fly using only the sun's energy. The first Solar Impulse plane was completed in 2009, and it achieved a significant milestone by flying for 26 hours over Switzerland, becoming the first solar-powered aircraft to fly through the night.12

The project later developed Solar Impulse 2, a larger aircraft designed for a round-the-world flight attempt. This journey began in March 2015 and was completed in July 2016, marking a historic achievement in aviation powered entirely by solar energy. These aircraft are very lightweight and utilize solar panels to convert sunlight into power for electric motors.12
