The Solar Impulse 2 is a second generation airplane powered completely by the sun. The first generation Solar Impulse had many successful flights and the team used the experience and data from these flights to design the Solar Impulse 2.
About the Plane:
- This revolutionary single-seater aircraft made of carbon fiber has a 72 meter wingspan (larger than that of the Boeing 747-8I) for a weight of just 2,300 Kg, equivalent to that of a car.
- The 17,000 solar cells built into the wing supply four electric motors (17.5 CV each) with renewable energy.
- During the day, the solar cells recharge lithium batteries weighing 633 Kg (2077 lbs.) which allow the aircraft to fly at night and therefore to have virtually unlimited autonomy.
