The plane, Solar Impulse 2, touched down in the United Arab Emirates capital at 0005 GMT on July 26. It first took off from Abu Dhabi on March 9, 2015, beginning a journey of about 40,000 km (24,500 miles) and nearly 500 hours of flying time.
Bertrand Piccard and Andre Borschberg, the Swiss founders of the project, took turns piloting the aircraft, which has a wingspan larger than a Boeing 747 but weighs no more than an average family car. "More than an achievement in the history of aviation, Solar Impulse has made history in energy," Piccard, who piloted the plane on the last leg, told a large crowd on landing.
He said the technologies used on Solar Impulse 2 could be used on the ground in daily life to halve emissions of carbon dioxide, the main greenhouse gas blamed for climate change. The propeller-driven aircraft's four engines are powered by energy collected from more than 17,000 solar cells built in the wings. Excess energy is stored in batteries.
