A solar has been developed and its mission is to try and fly around the world.
The plane is called the Solar Impulse 2 and has a huge wingspan of 72 metres – equal to that of a Boeing 747 plane.
However, the plane is very light, weighing about the same as a large car.
The plane gets its energy from the sun using 18,000 solar cells that are on the wing.
The cells convert sunlight into electricity to power its motor and to store in its batteries.
The global flight is set to take off next year. The Swiss team behind the project has already flown a previous solar plane across America.
