Solar airplane Solar Impulse is almost ready to perform his first big flight: the flight from one U.S. coast to the other, using only solar energy.
The company works on a single-seater aircraft since 2006, with trials in Europe and Africa. The latest version of the aircraft (wingspan of 80 meters, with 12,000 solar cells on the wings and fuselage, which operate four motors) can reach speed of 64 kilometers per hour and can stay in the air 36 hours. However, it is unable to make the trip with hust one flight, so several stops will take plane: in Phoenix, Dallas, Missouri and Washington, to New York.
The project of the solar aircraft began in 2003 as a study at the Swiss Federal Institute of Technology, where a flight around the world on a plane that moves thanks to solar energy by improving the efficiency of solar cells.
Hopefully, the flight of the Solar Impulse will begin on May 1, while an attempt for a trip around the world will take place in 2015.
