This month more than 300 LED lights were illuminated by the Dutch company Plant-e in a new energy project called Starry Sky." Although the bulbs were ordinary, the electricity running through them derived from a new process that harnesses the power of living plants. "Starry Sky" and a similar project an hour's drive away, near Plant-e's Wageningen headquarters, are the two first commercial installations of the company's emerging technology ... fueled by the byproducts of living plants. Plant-e's co-founder and CEO, Marjolein Helder, believes that this technology could be revolutionary. For decades, middle schoolers have been engineering clocks made from potatoes, which run on a similar principle. Plant-e's technology is the first to produce electricity from plants without damaging them. Both projects that lit up the Netherlands this month involved native aquatic plants that were supplied by local greenhouses. The process involves plants growing in modules-two-square-foot plastic containers connected to other modules-where they undergo the process of photosynthesis and convert sunlight, air, and water into sugars. The plants use some of the sugars to grow, but they also discharge a lot of it back into the soil as waste. As the waste breaks down, it releases protons and electrons. Plant-e conducts electricity by placing electrodes into the soil.
