How do you know it's salt water?
And I always thought 'salt water' wasn't salty enough for any sort of useful battery. I know about galvanic corrosion and all that, but that seems a bit short on juice. Maybe enough to keep a cap charged up for a burst of juice when it wakes up? Might be an interesting thing to try out someday...
