Steampunk is a subgenre of science fiction that incorporates technology and designs inspired by 19th-century fashion and industrial machinery (including steam-powered machinery, hence the name). Steampunk fiction often explores the anachronistic idea of what would have happened if society built upon steam as a primary energy source and maintained the Victorian visual style.
Steampunk engineering often includes visible gears and screws, as well as analog clocks, steam-powered machines (including vehicles such as airships that often carry flying wooden ships), rotating propellers and dials. Those are always made of metals, wood, or even glass, but never plastics or other modern materials.
