	a few ideas: 

1)	increase surface area of plates
	more sureface area = more current

2)	switch to a lower current light....
	It may be possible to find an LED that will light with
	0.2 or mA... however the voltage drop will be more.
	Try hewlett packard optoelectronic products... good stuff

3)	pick more dissimiliar metals
	maybe Zinc and Copper

4)	pick more acidic lemons
