That was sort of what I was thinking, y'know maximum or dallas used to make some great little charge pump devices, you could maybe glue something together to maintain a small nicad, who knows how large a device he has under water, I know Zinc is really reactive with other metals, if it is of any size it could make pretty good current for quite a long time. I do not know it's salt water. I guess it might be a lake somewhere, 500 feet is pretty deep. Speaking of current, maybe there is water current harvestable to make power.
Problems cannot always be solved with in the box answers, I figured 500 feet was too deep for solar
