Solar plane - level 2
A revolutionary plane made its first flight in Switzerland. The plane is as light as a car, and it is the product of 12 years of research.
The plane uses the sun and only the sun to fly. It has 17,000 solar cells on its surface. It collects enough energy to fly during the day and collects energy for the night. The plane can fly day and night. It can fly for weeks and even months.
If tests are successful, the plane is going to fly around the world. The round-the-world trip will take five days and nights in March 2015.
Difficult words: research (study), solar cells (things that turn light into electricity).
You can read the original story and watch the video in the Level 3 section.
