Solar Impulse 2 completes historic round-the-world trip

The Solar Impulse 2 has become the first aircraft to circle the globe using solar energy after landing in Abu Dhabi on the last leg of its journey.
In its journey, the long-range solar-powered aircraft has travelled 26744 miles across four continents, three seas and two oceans since setting off from Abu Dhabi in March 2015.
Key features of Solar Impulse 2

  • Solar Impulse 2 is a Swiss long-range solar-powered aircraft project. It is first aircraft to fly day and night without consuming conventional fuel in oder to promote renewable energy.
  • Its construction was started in 2011. The first test flight of the aircraft was conducted in the United States in 2013.
  • Structure: Single-seater aircraft made of carbon fibre. It has a 72 metre wingspan and weighs 2,300 kilo grams. It is solely propelled by the solar energy and emits zero Carbon dioxide (CO2).
  • Solar cells: 17,248 solar cells inbuilt into its wings. These cells supply renewable energy to propel the electric motors of aircraft.
  • These solar cells also recharge 4 lithium polymer batteries mounted on aircraft which allows it fly at night.
