Use copper with zinc, and forget the aluminum. I realize that
finding pure zinc in the household environment may be difficult, so try
using a piece of galvanized sheetmetal. Increase amperage by increasing
electrode surface area (bend into a semicircle is one possibility).
Also, connect lemons in parallel. We won't talk about adding a
depolarizer... :-)
