No Punk In This Steam

"Steampunk" is a science fiction/fantasy genre in which steam provides the primary motive power for the technology of the story.  Victorian Britain is a common setting for such tales.  In this article from the March 1941 issue of Popular Mechanics, posted on Modern Mechanix, we learn that the importance of steam was fact, not fiction, just before World War II.  One of the commenters to the post stated that he/she works for a company that still produces steam turbines, and the basic design has not changed since the 1940's.
