Lemon battery - Magical Realist - Sep 19, 2015
I was thinking of sticking a copper nail and a zinc nail into a lemon and connecting an LED between them. Would it be enough to light it? Find out here:

Better yet, create some LEDs with a zinc coated and copper coated lead, then poke them all into the lemons of a lemon tree. Naturally powered christmas decoration!

That would be a good science fair project. I recalled potatoes being used also, and I found a link.

Wow...a potato creates even more voltage. I wonder how much a grapefruit generates? A pineapple?

I found it surprising that it was higher for potatoes than lemons too.
I wonder how long a vinegar or muriatic acid battery would light an LED. Vinegar in a plastic container, for example.
Or maybe a solar cell charging a super capacitor. Would the capacitor store enough charge to light an LED overnight?
