Communities around the Chesapeake Bay are already suffering the effects of climate change and rising sea levels. Places such as Virginia Beach are highly dependent on coastal tourism and aquaculture and will lose up to $8 billion from dying ecosystems, eroding beaches, and flooding due to climate change. Cities like Norfolk are regularly flooded, threatening people's livelihoods, closing schools, and damaging infrastructure. Tangier Island will be completely underwater and cease to exist due to sea-level rise and erosion. To fight these issues, I propose ‘BIOWATT,’ a cost-effective, three-pronged approach for shoreline protection, ecosystem regeneration, aquaculture, and power generation. Unlike conventional solutions, BIOWATT rebuilds beaches while creating new marine habitats and generating renewable power. BIOWATT uses readily available, already-existing components and technologies. To construct BIOWATT, I will use off-the-shelf electronics, floats, sheet steel, and rebar, eventually scaling up to large-scale manufacturing. I am currently running a test installation in the Lynnhaven River, studying the effect of BIOWATT on oyster growth in the Chesapeake Bay. Moving forward, I plan to work with environmental organizations such as the Chesapeake Bay Foundation, Virginia Institute of Marine Science, and Global Coral Reef Alliance to implement BIOWATT in areas where seawalls would be harmful or undesirable.
