Engineers say they have carried out the first-ever flight of an electric airplane with no moving parts. Researchers at the Massachusetts Institute of Technology, or MIT, recently shared video of the successful test flight. They also reported their results in the scientific journal Nature. An airplane usually requires fast-turning turbines to create the necessary thrust and power to lift the plane off the ground and stay in the air. But MIT researchers say they have created a new air vehicle that powers itself without this kind of engine. In fact, the plane was designed to have no moving parts at all. Engineers say that developing and expanding such technology could greatly change the future of flying. It could lead to the creation of planes that are safer, quieter and easier to take care of. Such planes would also not produce emissions that harm the environment.
