The Solar Impulse 2, a solar plane which we mentioned in an earlier publication took off for the first time today. The solar plane is made to make the round of the world at 2015, but today it took off on its inaugural flight from Payerne to an airport in Switzerland.
This is a larger, upgraded version of the aircraft that flew across America last year with Bertrand Piccard and Andre Borschberg.
The two men want to expand the boundaries for alternative sources energy and they think their plane is a pioneer.
The Solo Impulse 2 weighs just 2268 pounds and has 72-wide wingspan covered entirely with solar cells.
The solar cells are over 17.000 and the builders hope that is enough for his big one taxid. Its creators say the single-seat aircraft is more efficient and generally better built than its predecessor. Solar Impulse 1 made five full-day flybys across the Pacific and Atlantic without reporting any problem.
