    The Energy Generated from A Single Orange: A Citric Acid Battery by Caleb Charland



    By Christopher on November 15, 2012

    This orange battery was built by photographer Caleb Charland (previously) as part of his ongoing alternative energy photographs using fruit, vegetables, and other objects to create light for his long-exposure photographs. The electricity powering the lightbulb inside the orange is generated through a chemical reaction between citric acid and the zinc nails inserted into each wedge. I think this is by far the most lovely piece he’s done in the series, but before you start work on a bunch of orange lights to keep on the nightstand, the light generated was so dim this particular photograph required a 14 hour exposure.

    I've heard about this before. I think my high school science teacher said that it was possible...of course, this was 10+ years ago.
