When moss photosynthesize, they release nutritious fats, carbs and proteins into their roots to feed colonies of helpful, symbiotic bacteria. In the process of breaking down these compounds, the bacteria release electrons. In other words, the create electricity. Researchers at the University of Cambridge have figured out how to harness these minute electrical charges into an emerging technology called biophotovoltiacs (BPV).
Created by Alex Driver, Carlos Peralta, Paolo Bombelli, the prototype Moss Table produces enough electricity to power a small lamp. According to Peralta, the Moss Table “suggests a world in which self-sustaining organic-synthetic hybrid objects surround us, and supply us with our daily needs in a clean and environmentally friendly manner.” Small devices could be powered by houseplants or backyard gardens, while larger arrays of plants might hold promise as a new renewable source of energy, especially in remote or impoverished communities.
