There are many iconic things about Star Trek, from the communicators that inspired flip cell phones to the unmistakable silhouette of the USS Enterprise. However, one of the most iconic elements of Gene Roddenberry's universe are the transporters that "beam" characters from one place to another. This technology is one of the earliest and most high-concept ideas in those early shows. Yet, it was born -- like so much in television production -- out of a need to save money. So, how does the fantastical transporter system work? If someone who wasn't a fan of Star Trek was asked to quote a line of dialogue from the show, they most likely would say, "Beam me up, Scotty."
