You've probably plugged lights into potatoes during science lessons -- but not on this scale. For this photograph (above), taken for Wired in the summer of 2012, Caleb Charland spent two days wiring 300 potatoes to a lamp, and shot the results. "I remembered doing potato batteries in school," the Maine-based artist says. "It just went from there."
Charland began merging science and photography in 2005, inspired by primary-school books of experiments, but only took his work outdoors in 2011, when he wired a 240-hectare orchard to the lamp used here. "It's not a functional supply of alternative energy, but it suggests that there is this electricity, this inherent energy in nature," says the 32-year-old. Working outdoors, though, is risky. "It's more nerve-wracking. I try to leave as few variables as possible. And it took a lot of time just to find a potato farmer." Charland found his in a bar and drove the six hours to his field. The lamp runs on 3.5 volts and looks brighter in the final work due to its long exposure -- which also allowed Charland to capture star trails. "I was expecting to get a few of those in there, but then when nature has her way... That's her brush-stroke."
In summer 2013, he will return to the same field to try connecting the lamp to a harvest of beets, and hopes to visit a vineyard in southern Italy. "I tried it with a bag of grapes at home," he says. "It took 120 grapes to get 1.5 volts. You do the maths."
