Photo captures electrical power of an orange

Photographer Caleb Charland specialises in photographs that mix science and photography. Recently he has been working on photos showing alternative sources of electricity and his latest image is one showing the energy contained within an orange. The light seen in the frame is coming from an LED light held at the center of the orange slices. All the electricity comes from the orange itself: the nails inserted into the wedges react with the citric acid within them, and copper wires direct the generated power through the light. Charland writes that unlike his previous images, he wanted to shoot one that involved only a single piece of fruit: "Recently one Sunday I spent the day at the kitchen table playing with oranges, copper wires and galvanized nails. My hope was that I could make this on going project work with a single piece of fruit. I tried cutting it into slices and wedges but that ever present voice in my head reminded me the simple the better. It only seemed logical to use the orange’s natural wedges as the cells for the battery. The wedges are held up-right with an armature of small wooden skewers."Source: Fresh Plaza
