Calling all pilots and lovers of flight - these wallpapers are just for you!
There is something amazing about the ability of humans to defy gravity and take flight!
An engine or motor is a machine designed to convert energy into useful mechanical motion.[1][2] Heat engines, including internal combustion engines and external combustion engines (such as steam engines) burn a fuel to create heat, which then creates motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others—such as clockwork motors in wind-up toys—use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create motion.
