October 21, 2015. If you are a fan of science fiction, you may or may not remember the seemingly innocuous date dialed up in a DeLorean in the Back to the Future film trilogy (the second film, to be precise). Of course, it was just a film, but just in case: And on a slightly more serious note, one Japanese inventor has made a real-life imitation of the DeLorean from the movie. It can even run on cotton fibers made into bioethanol from old clothes! See here.
