A better water wing to harvest tidal energy

The eternal ebb and flow of tides — 24 x 7 x 365 — 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.”

PROVIDENCE, R.I. [Brown University] — When it comes to raw power and absolute reliability, it doesn’t get much better than the tides. That’s why tidal power is such an attractive option as a renewable form of energy. But designing a device to gather tidal energy in shallow water, where the ebb and flow move fastest and the energy potential is highest, has proven problematic. (more…)
