A solar-powered plane its inventor hopes will lead to a non-stop round the world flight was unveiled today.
Solar Impulse has the wingspan of a Jumbo Jet but the weight of a small car.
Adventurer Bertrand Piccard who in 1999 co-piloted the first round-the-globe non-stop balloon flight said: "Yesterday it was a dream, today it is an aeroplane, tomorrow it will be an ambassador of renewable energies."
The plane will have test flights over the next two years, and based on their results a new version will be constructed for the big event in 2012.
The plane will fly day and night using almost 12,000 solar cells, rechargeable lithium batteries and four electric motors. It will not use an ounce of fuel.
