	A typical LCD digital watch will run for over a year on a 60 maH silver
oxide cell.  That works out to a current of around 7 microamps.  Most of
the watch circuits quit working when the voltage drops below about 1.1,
so you might need a couple of potatoes in series.  Of course, they'd dry
up or rot long before the year was up.
