The Lemon Jacket uses a “lemon battery” to create electricity for a light. The lemon battery is made by inserting two different metals (galvanized iron and copper) into a lemon. The metals work as electrodes, producing an electrochemical reaction that generates a small amount of voltage, with the lemons providing the necessary acidic environment. Four lemons, copper, iron, and wires can create enough energy for a small LED lamp. The Lemon Jacket thus becomes a portable battery that lights my way when I am out in the woods.
