Oysters from Chesapeake Bay, Library of Congress
Oysters are little nutritional bombshells. They're packed with vitamins, minerals, protein, fatty acids, and particularly of note during Covid: Vitamin D and Zinc. More than 80% of hospitalized Covid patients were found to be lacking Vitamin D, and those with low zinc levels tended to fair worse with the virus than those with healthy levels.
Solar Oysters has designed a solar powered barge that will farm oysters vertically through the water column in the Chesapeake Bay area. Elizabeth Hines is the Vice President of Maritime Applied Physics Corporation engineering firm that's working on the design.
While solar panels aren't usually the best option for electricity grids, due to their intermittency and need for fossil fuel or nuclear backup, off-grid solar panels produce clean, free energy once built and installed. Oysters are a sustainable source of protein and nutrients that require little inputs.
