(Uses for silver)
There a quite a few:
- traces on PCBs as well as contacts for superior conductivity
Can't say I've ever seen a silver-plated PCB. I've seen tin-plated and
gold-plated, though.
- batteries
Ah, good old silver-oxide watch batteries. Forgot about those. The
slightly longer-life alternative to alkalines that nobody seems to stock
(LR44s are everywhere but SR44s are considerably harder to find).
Also as a permanent germ killer (silver is rather
unhealthy to a lot of
germs, while quite harmless to humans).
*searches the Wiki*
Huh. Forgot about that one too.
Silver tableware? Although that's on the boundary line between ornament
and tool...
