The plane took its first international flight from Switzerland to Brussels on May 13 and then marked its second international flight to Paris. It has 12,000 solar cells mounted on the wings, which provide momentum for its four electric motors.

Solar Impulse is the first aeroplane designed to fly day and night without requiring fuel and without producing carbon emission. The 64-meter-wingspan (as wide as an Airbus A340) can fly at extremely slow speed and has a weight equivalent to that of an average family car.

Regarded as a "special guest" in the show, Solar Impulse made a historic 26-hour day and night flight without fuel in July 2010.

During the Paris air show from 20 to 26 June, visitors can enjoy a close look at the innovative plane on ground every day and if weather condition permits, flying displays will take place.

According to Paris Air Show organizers, 59 of the top 100 companies in the air industry worldwide will be present. More than 1,800 small and medium-sized companies will be exhibiting their products during the one-week show.
