Harnessing marine hydrokinetic energy proves viable in Mass Maritime test

Wicked Local News

Massachusetts Maritime Academy at Buzzards Bay is taking another step toward becoming a veritable renewable energy center for Southern New England.

MMA officers and staffers huddled at State Pier Tuesday morning (Aug. 9) along the Cape Cod Canal to inspect and gauge a first-in-the-nation oscillating hydrokinetic turbine technology that has been reliably tested in the waterway’s swift currents.

On the Taunton River, Brown researchers pursuing future of tidal energy.

Providence Journal

ABOARD THE ORCA — On a converted pleasure cruiser in the middle of the Taunton River, engineers at Brown University are testing a device that they are betting on to transform how the flow of water can be harnessed to produce electricity.

Suspended below the hull of a vessel that students found on Craigslist and christened the “Orca” — an homage to the trawler in “Jaws,” quips doctoral student Michael Miller — are posts fitted with sleek wings that move up and down as the boat cruises through the choppy waters, generating a constant stream of power.

Capturing A River’s Energy With Wings

RI Public Radio

Humans have been harnessing energy from rivers for thousands of years. Think water wheels from Ancient Greece and modern hydropower plants, like the Hoover Dam. Brown University engineers have a new take on a hydropower device that could harness enough energy to power communities in remote locations or along fast-flowing rivers.

Brown harvests energy with water wing

Brown University News 

The eternal ebb and flow of tides makes them a dependable source of energy, but how to harness all that, especially in shallow water? Shreyas Mandre and colleagues at Brown have developed an efficient water wing and optimized its performance with a “secret sauce.”
