Any stroll through a school science fair proves that potatoes are a simple source of electricity. But did you know that enough apples, about 300, can power an LED lamp? Time to get planting!
This remarkable image was taken by photographer Caleb Charland, who found that it only took about 10 apples, wired in series, to power each of the 30 LEDs in this lamp he built.
Interestingly enough, the evening he took this photo he had to scare off a herd of deer hoping to feed on the fruit -- for the entire four hours it took to capture this long-exposure shot. So in other words, the glowing results pictured are probably not indicative of how bright the lamp actually was. Now what the heck am I going to do with all these apples?
