Paddlewheels churn, water circulates (in foot-deep, oval “raceways”), and sunshine fuels countless millions of tiny photosynthesizing organisms (all of the uniquely suited species Nannochloropsis salina) in a greenhouse at Touchstone Research Laboratory’s experimental algae farm at Cedar Lane Farms near Wooster in northeast Ohio. The facility hosted an open house this past Wednesday. Algae produced here will be turned into biofuel. OARDC is a partner on the project. More here and here.
