Eco-friendly air travel is possible, and the proof is in this solar-powered plane. Within a decade in development, the Solar Impulse project has delivered some truly groundbreaking results, underlining some pretty exciting implications for the future of flying.
Over 17,000 solar cells cover the entire top of the Solar Impulse 2, harnessing enough energy from the sun to keep it flying overnight and in overcast conditions. Even with the hi-tech composition of this sustainable aircraft, its weight is comparable to a family car, making it an efficient ride all-round. To ensure that it keeps stable, this solar-powered plane has been equipped with a wingspan of 72 meters. All of this cutting-edge technology is being put to the test in a five-month global journey that will take the Si2 around Europe, Africa, North America, and Asia in one trip.
