An Ashland company has found a new use for duckweed; it can light your home. Pacific Domes of Ashland, a company that makes geodesic domes, has teamed up with an east coast engineer who has figured out how to generate cheap, clean electricity from duckweed, which grows on ponds and other still or slow-moving bodies of water. They say their patented system is capable of producing a megawatt of electricity for the same price as coal or nuclear energy and significantly cheaper than wind or solar.  The systems can power a single home or be expanded for a municipal utility.
