An Encyclopedia of Sci-Fi Technology?
RobotWisdom asks: "Is there a wiki somewhere that I haven't found, dedicated to cataloging all the technological innovations imagined by science fiction writers? So that if someone wants to explore a particular class of innovation like weapons, or medical, or transportation, they can (eventually) easily find summaries of all the major thinking on that topic? And if it hasn't been started yet, does anyone have the wherewithal to start it?" If such a thing isn't available in one place, what sites have you found that catalog the technology of specific sci-fi mythologies?
Some misguided trekkies would send you to Memory Alpha, but that place is strictly bush league. If you want the best in Treknology, all the way down to fictional elements and even elementary particles, you've gotta head to Ex Astris Scientia. When I found this place, it blew my freaking mind.
Engage!
You can't win, Darth. If you mod me down, I shall become more powerful than you could possibly imagine.
Try this: http://www.technovelgy.com/ The site lists sci-fi stuff and real world instances of that tech.
I also suggest Orion's Arm. It's a "reference" for a pretty in depth sci-fi universe and has a nice encyclopedia of tech and social ideas.
