Sure.. Proper use of food!
A pot of beans can also light up a room when properly

Potatoes may be cheap enough, but add the cost of cooking and
replacement zincs, do you really have something worth bragging about?
And it took a university "scientists" to "discover" what has been a
kid's toy to power LCD clocks for 20 years or so?
Doubtless a paper towel or other fibrous material wetted with salt
water or vinegar would work as well....
Not having a source of strip zinc. I made batteries from those
compartmentalized plastic parts boxes using strips of copper and
aluminum flashing bolted together and slipped into adjacent salt water
filled compartments and powered transistor radios in the 60's.
