Subject: edible battery to power clock

I need to know how to make an edible battery that has enough voltage to power a 
potato clock.  I cannot use potatoes, fruit, pop, fruit juices, or foods 
containing fruit juices.  I had thought of potato and lemon but cannot use 
either of them.  
Thanks for your help.

That is the instructions on my worksheet from my science teacher.  We can use
vegetables, just not potatoes.  I thought it sounded kind of strange as well.

Let me know if you need any more information.  Thanks for your help.

I cannot use lemons since they are considered to be a fruit.
