Q:
I’interested in altenative energy and I’m trying to invent way to use potatoes and lemons in my inventions so I need a way to get more amps with less potoatoes and lemons and is there a way to recharge them?

A:
These vegetable batteries are very weak power sources, in part because it's hard for ions to move through them. At any rate, the real free-energy input that drives them is from the pure metals used as the electrodes. That's what's used up as the battery runs, and so that's what would have to be recharged.

I'm afraid the best way to get energy from a potato is to eat it, although if it's dried out it could be burned instead.
