Tidal currents occur in conjunction with the rise and fall of the tide. The vertical motion of the tides near the shore causes the water to move horizontally, creating currents. When a tidal current ...

Berkeley engineer Evan Variano explains how underwater kites could expand the world’s renewable energy portfolio ...

It uses lift generated by tidal flows to fly patterns faster than the currents, harvesting renewable energy. Solar energy is the bedrock of most renewable energy grid plans – but lunar energy is even ...

DOE says the funding opportunity represents the "largest investment in tidal and river current energy technologies in the United States." Over the past few years a number of projects related to tidal ...

As the tide rises and falls, is it worth generating electricity on a large scale from its movement? It’s a question engineers have studied for one particular part of Great Britain since the 1800s—and ...

Tide levels can vary by almost a meter across a single bay, according to a new study that uses decades of satellite images to measure tides at the scale of individual beaches. Researchers at ...
