Photographer Caleb Charland takes pictures of batteries made out of power sources like stacked coins, fruit, and vinegar. But maybe his most impressive trick was wiring up this apple-powered battery using fruit that was still on the tree.
Charland inserted a galvanized nail and a copper wire into each apple to make his live-apple battery. Ten apples wired together produce enough current to light a single LED, and Charland used 30 LEDs (so, 300 apples) for the lamp in the photo. Combine that with the fact that apple orchards are fairly stationary, at least when not populated by Ents, and you start to think that this is maybe not the most realistic alternative energy solution. But it sure looks pretty!
Here’s a video of how Charland put the whole thing together:
