Solar Impulse is a Swiss solar powered aircraft that made aviation history by flying through the night and non-stop for 26 hours. Andre Borschberg, flying from Payerne, Switzerland, flew for 14 hours in sunshine to generate electrical power for its four electric motors (each rated at 10hp, 6kw) and to charge its batteries for the night flight.

The wingspan of 63m (206ft), similar to an Airbus A340, and a large 200sq.m (2,152sq.ft.) wing area, is covered in 12,000 solar cells. The plane weighs only 1,600kgs (3,530lbs), with 400kgs (880lbs) of lithium ion battery packs used for night time flying, providing power for the engines that drive 3.5m (11.5ft) diameter propellers.
According to Borschberg, who practiced yoga to maintain circulation, energy, and stay awake for the mission, "The flight was really zen. It's very peaceful, during this time you have the time to think and to concentrate."

The project aim is to demonstrate clean energy and fuel efficiency is technically achievable and should applied be to aviation and transport in general. They have plans for longer flights and ultimately transatlantic and round-the-world flights in 2013-2014, with a second plane with better aerodynamics, improved power and improved power efficiency and are looking for new partners to provide 20% of the funding needed in its €75 million ($95M) budget.
