An electric aircraft is a type of plane powered by electric motors instead of a regular engine. Electric motors can be powered by batteries or by a fuel cell that runs on hydrogen. Electric aircraft are much quieter and less polluting than traditional planes because they don't produce exhaust or make much noise. They can also fly for longer distances on batteries because they don't need to carry as much fuel. Electric aircraft are usually smaller and lighter than regular planes, so they are more efficient and use less energy. They are also safer, since there is no risk of a fire caused by spilled fuel.
