Solar Impulse 2 landed only with solar energy

Solar Impulse 2 fulfilled its mission, and as the first ever aircraft to use only solar energy, it circled the Earth.

A year and a half since the start and 42 thousand. The kilometers traveled in seventeen stages, Swiss pilots Bertrand Piccard and Andre Borschberg landed in Abu Dhabi.

Solar Impulse 2 is not a technological breakthrough. It is rather an “impulse” to change the thinking of solar energy. It was an indication that it was a viable alternative to fossil fuels, even with such sophisticated aircraft as aircraft.

The engines and airplane systems were powered by seventeen thousand solar cells placed on the wings and the Solar Impulse 2 hull, at night using the energy accumulated during the day in batteries.

During the trip, during a flight over the Pacific, a record of the time and distance of the flight of the solar plane was broken. Solar Impulse 2 is not a speed demon, its cruising speed is 88 miles per hour (about 140 km / h).

Both pilots had to spend hours in the cockpit of the telephone booth, wearing oxygen-supplying masks at high altitudes, and sleeping up to a maximum of 20 minutes at a time.
