Swiss adventurer Bertrand Piccard has unveiled a prototype of the solar-powered plane he hopes eventually to fly around the world.
The initial version, spanning 61m but weighing just 1,500kg, will undergo trials to prove it can fly at night.
Dr Piccard, who made history in 1999 by circling the globe non-stop in a balloon, says he wants to demonstrate the potential of renewable energies.
He hopes to fly a later version of the plane across the Atlantic in 2012. |
