Photographer Caleb Charland, based in Portland has expanded his series of powered batteries to include pomelos and grapefruits. Caleb uses copper wires and galvanized nails to harness energy from the citric acid in the fruits that he chooses.

Caleb has previously used oranges and vinegar where each food acts as a natural cell for the batteries he creates. However, the light created from these batteries are so low they required a 14 hour exposure to capture the illumination.

Caleb seamlessly fuses art and science by capturing beautiful images of these projects and reminding us of the power of the things we see every day.
