The makers and pilots of a solar-powered plane will try to fly it around the world beginning next month. The plane is called “Solar Impulse 2,” or SI-2. It arrived in pieces recently in Abu Dhabi in the United Arab Emirates. The plane’s material is mostly plastic strengthened with lightweight glass. It is now being assembled and prepared for its journey around the globe. The SI-2 team plans to fly around the Earth in 25 flying days over a five month period. The idea was first tested by Solar Impulse 1 which made several flights. One was from Switzerland to Morocco and another flew across the U.S. The plane’s wings are 72 meters across. They are covered with more than 17,000 solar cells. These special energy storage containers provide power to the batteries that permit the plane’s four electric motors to operate at night. Only one person can sit in the SI-2. In March, the first pilot will take off from Abu Dhabi and fly along the equator, where the sun’s rays are strongest. The plane will land every few days so that the two pilots can take turns flying it. Bertrand Piccard is one of the pilots. He also helped create the project. He says the flight around the world is very exciting, but it also takes a lot of preparation. He said the team needs to deal with very long flights, and there will be a lot of stress or pressure for everybody. Bertrand Piccard says the goal of the project is to show that renewable energy and clean technologies can be used for other projects. He said, “If an airplane can fly with no fuel around the world, can you imagine how this technology could be used everywhere?”
