When most people think of fruit they envision delicious juicy treats with succulent flavors. Yet fruits have another commonly overlooked trait: viable sources of electricity. Photographer Caleb Charland experimented on a large scale with this philosophy and about 300 apples from an apple orchard in Newburgh, Maine. In fact he then discovered that he only needed 10 apples to supply enough energy to light up the 30 LEDs inside his lamp.

Interestingly enough some fruits and vegetables can provide a current strong enough to act as a battery or rather the exchange of neutrons between the 2 electrodes produces the electricity.
But what foods produce electricity?
- Foods high in acidity or potassium
- Citrus fruits (oranges, grapefruits, limes and lemons) act as an electrolyte that conduct electricity.
- 1 lemon can produce 7/10 of one volt of electricity
- Raw potatoes (potassium)
- Tomatoes (potassium)
- Carrots (potassium)
- Sweet potatoes (potassium)
- Cucumbers (potassium)
- Pickled Foods – such as pickles, conduct electricity due to their salt content
- Salt is high in ions and conducts electricity
- Foods high in salt content will produce electricity
- Electrical power increases as you connect more fruits
