The zero-emission electric and solar airplane, capable of flying day and night without fuel.
The Solar Flight is on a total of 21 days of flight travelled round the world
Solar Impulse 2, a lightweight aircraft with the wingspan of a Boeing 747, has just completed a 27,000-mile (about 43,450-kilometre) journey
around the world. It is entirely powered by sunlight through 17,000 solar cells built into its carbon fibre wings, with no fuel or polluting emissions.

The journey took Piccard and Borschberg from Abu Dhabi, the departure and arrival host city, to India, Myanmar, China, Japan, across the United States from Hawaii to New York, Spain, Egypt and back to Abu Dhabi.(ens-newswire.com)
The Swiss-made plane can reach an altitude of some 30,000 feet, flying at a top speed of about 70 kilometres per hour. After 12 years of intense research and development, on March 9, 2015, the Solar Impulse 2 began its attempt to fly around the world with no fuel.
As with all great firsts, there was no pattern to follow. Strategies had to be invented on the wing to allow Solar Impulse 2 to fly across the Pacific for five consecutive days and nights, and become the first solar airplane to accomplish an oceanic crossing.
This historic and record-breaking flight from Japan to Hawaii was achieved by Borschberg in July 2015, who says the team has proved that clean technologies can accomplish incredible things.
