Voyager "Year of Hell":
JANEWAY: It's beautiful.
CHAKOTAY: Nineteenth century, mechanical movement. It's a replica of the chronometer worn by Captain Cray of the British Navy, His ship was hit by a typhoon in the Pacific. Everyone back in England thought they were killed, but eight months later Cray sailed his ship into London harbour. There wasn't much left of it, a few planks, half a sail, but he got his crew home.
JANEWAY: I appreciate the sentiment, but I can't keep this. Recycle it. We can't afford to waste energy on nonessentials.
CHAKOTAY: Kathryn, I replicated this months ago. I've been saving it. I wanted you to have it.
JANEWAY: That watch represents a meal, a hypospray, or a pair of boots. It could mean the difference between life and death one day.
Wouldn't' it take energy to recycle something? If all they're looking for is raw materials, meaning matter, there's tons of wreckage all over the place. If all Janeway needed was metal which is what the watch is made of it was all around here. I was confused by this concept. Is replicated material special in some way once it's completed?
How does "recycling" this watch in some way benefit them?
