Aircraft that goes by means of solar energy

Solar Impulse, the first aircraft that operates entirely on solar energy, successfully performed a 18-hour trip from California to Arizona.
Phoenix was the first leg of the flight, which will lead plane, run by a Swiss pilot, across the United States without using fuel, but only energy from sunlight.

"It took a lot of preparation and an enormous commitment on the first flight. We have time to work on this thing and I do not believe that the first part ended, "said Bertrand Piccard, pilot.

Piccard adventurer touched down about midnight, and this is another of the Solar Impulse particular, the fact that using solar energy can fly as day and night
   Flight from Northern California was conducted at an average speed of 49 kilometers per hour. Piccard and copilot, Andre Borshberg plan to divide tasks making long stops in Phoenix, Dallas, St. Louis and Washington, before the final landing in New York next month.

The aircraft in question has wings of a 747 passenger plane, but the weight of an average car. He collects the sun's energy and stores in a battery, which enables even during night flights.

  But the greatest speed he can reach, since only 70 miles per hour, makes the necessary stops.
