Solar Impulse 2 will return to Abu Dhabi after a five-month journey with stops in Oman, India, China, Hawaii and New York, travelling 35,000km.
Abu Dhabi - A plane powered by the sun will attempt an unprecedented flight around the world next month, the project’s founders said, seeking to prove that flying is possible without using fossil fuel.
Solar Impulse 2 is set to take off from Abu Dhabi and its route, which was unveiled on Tuesday in Abu Dhabi, includes stops in Oman, India, China, Hawaii and New York. It will cross the Pacific Ocean and fly across the United States and southern Europe to arrive back in Abu Dhabi.
Although groundbreaking in its distance, the trip will not be undertaken at a lightning pace.
On its five-month journey of 35,000km, the engines will be powered only by solar energy. The two Swiss pilots will take turns at the controls in the tiny cabin for five consecutive days and nights in the air.
“Miracles can be achieved with renewables such as solar power. We want to show we can fly day and night in an aircraft without a drop of fuel,” Bertrand Piccard, one of the pilots and the project’s co-founder, told reporters on the sidelines of the World Future Energy summit currently underway in Abu Dhabi.
The plane, which has the weight of a family car (2,300kg) and a wingspan equal to that of the largest passenger airliners, will take off in late February and return by late July. Its journey will span approximately 25 flight days at speeds between 50 and 100km per hour.
Feasibility studies, design and construction have taken 12 years, said Andre Borschberg, the second pilot and co-founder.
“It is not the first solar airplane, however it is the first able to cross oceans and continents,” he said.
Piccard said of the challenge: “It is simply the unknown. It is a question of technical reliability, of human weather and it is the challenge of discovery.”
If something goes wrong, they will build another aircraft and continue the journey, he said.
“There’s a will in humankind to make a better world and find solutions to climate change.”
The plane is the successor of Solar Impulse, a pioneering craft which notched up a 26-hour flight in 2010, proving its ability to store enough power in lithium batteries during the day to keep flying at night.
