invented tech

I'm trying to put togerher a fake "shopping list". Not sure what I'll use it for, maybe a game prop, maybe a prop at Orycon.

I've got the first two items, I'd love suggestions for other made up tech from SF movies and TV. I'd prefer parts or "modules" to entire devices.

Anyway:

1. Flux capacitor (From "Back to the Future")
2. interocitor (from "This Island Earth")

Not sure if Iwant stuff like dilithium crystals.
