According to Sky News, NASA has unveiled an all-electric plane which it has been developing since 2015.
The experimental aircraft, or X-plane, has been designated X-57, and will be known as "Maxwell" for short.
The X-57 has been adapted from an Italian-made Tecnam P2006T twin-engine propeller plane but with the traditional combustion engines replaced with electric cruise motors.
NASA hopes that new electric plane will help fight climate change.
