All the batteries? Then you'd better do that before Friday!

To fabricate a cell with dissimilar metals + salt water electrolyte you
simply search in the sand for different bags of dubloons--and hope they
came from batches of alloy sufficiently dissimilar to generate a worth-
while potential difference. If not, then jump the next pirate who comes
ashore and steal his sword: it's iron or steel. Use that as one of the
electrode metals for your battery. But you can't escape the island in
the pirate's rowboat, that would be against the spirit of adventure ....
