Orange Powered Battery Photo From Caleb Charland
Caleb Charland writes on his blog that while playing with oranges, copper wires and galvanized nails. Now using only the natural wedges held upright with armature of small wooden skewers as the cells for battery, he made the LED work, though he required 14 hours of exposure to do it! This citric acid battery is definitely a treat for the eyes. All thanks to Caleb, who is a famous photographer with work displayed globally.
