battery made from pomelo and grapefruits by caleb charland
portland, maine-based photographer caleb charland has expanded his series of food-powered batteries with his latest piece using pomelos and grapefruits.
charland manipulates copper wires and galvanized nails to draw energy from the citric acid present in slices of grapefruit and pomelo,
with earlier iterations including oranges and vinegar, where each foodstuff acts as natural cells for the battery.
though the light projected was so faint that it required a 14 hour exposure to capture the illumination,
charland manages to fuse science and art to create striking imagery - reminding us of the power of nature and raw materials.
