Haven’t had time to poke around here much, but a great idea for a web site:
Explore the wide variety of inventions and ideas of science fiction writers – over 675 are available on Technovelgy (that’s tek-novel-gee!). Use the Timeline of Science Fiction Invention or the alphabetic Glossary of Science Fiction Technology to see them all, see the category that interests you, or check Science Fiction in the News and watch sf come to life.
