One of the workshops I attended was an author panel and one of the questions asked, "Why do you believe steampunk is so popular today?" came up. One author said something along the lines that the Victorians were dealing with financial difficulties, as well as social and ethical questions and linked it to what we are going through now. I had never really thought that through before but as soon as she spoke I realized she was correct. People are looking into the past to try and figure out what to do about the future. The Victorian period was such a large and very fast growth of not only technology but social and ethical thought.
Today we've seen the music industry go from cassette tapes to CDs to MP3s. The book industry hasn't gone through as much transitions, but it has gone through a major shift to include electronic books. We can now take people who are not astronauts into orbit and have wireless networks built into a jet. What else might come to pass?
Tesla developed several designs of generators that people could build and operate without a lot of money, the radio and even a device the size of a small box that could shake his whole house and then the neighborhood.
