6. The Bond Glasses (The World Is Not Enough)
The other Bond gadget that might be fun to own? You guessed it: The X-ray glasses. Used in 1999's The World Is Not Enough, the special shades let our agent see through clothing to look for hidden weapons and -- ahem -- other "assets."
One caveat: If these ever get invented, please: No one tell the TSA.
7. The Replicator (Star Trek)
You know, I'm in the mood for a steak sandwich. If only I had some kind of contraption that could whip one up in a jiff...
Wait a minute: There is such a contraption. It just isn't in our universe quite yet. I'm talking about the replicator, the Star Trek-series device that synthesizes meals on demand. It doesn't stop with digestible delights, either: The replicator can create almost any object, ranging from breathable air to spare parts for your interstellar vessel.
Scientists have been working on similar technology for us earthlings for years -- and to their credit, 3D printing has come a long way -- but until I can get my on-demand steak sandwich, there's plenty of work left to be done.
8. The Transporter (Star Trek)
Star Trek's most famous gadget may also be its most impressive. The transporter takes you from one place to another in seconds, converting your body into energy and beaming you to a new location. And you don't even have to be named Scotty to operate it.
