What is the Swiss Solar Impulse 2?
The Swiss Solar Impulse 2 is a solar-powered aircraft designed to fly using only solar energy. It was a pioneering project led by Swiss aviators Bertrand Piccard and André Borschberg, with the aim of demonstrating the potential of renewable energy and clean technologies.
How did the Swiss Solar Impulse 2 achieve its solar powered flight?
The Solar Impulse 2 was equipped with more than 17,000 solar cells that covered its wings, supplying energy to four electric motors and charging four lithium polymer batteries during the day. These batteries then powered the aircraft during nighttime flights.
What were some of the challenges faced during the Swiss Solar Impulse 2's journey?
The aircraft had to contend with unpredictable weather conditions, long flight durations, and technical issues. The pilots also had to manage their energy consumption and rest while flying for several days and nights.
