Under the ocean’s surface, tentacle-like stems of seaweed sway with the current, bending back and forth as they get tossed about by underwater waves. These movements are a physical representation of ...

Irish company OceanEnergy has already tested its oscillating water column generators at significant scale in Hawaii, and it's just signed on to a four-year project to test, validate and commercialize ...

As a wave first hits the Waveline Magnet, the system gets a read on the size and speed of the wave, allowing it to fine-tune the power extraction at each generator as the wave moves down the line.

Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 trillion to 80 trillion watts of power worldwide—nearly two to three times the ...

For several years, CalWave has been developing its xWave clean power technology. Now, the company announces the completion of a long-term open-ocean test off the coast of San Diego, during which the ...

A high-tech machine that generates artificial waves is being installed at the Atlantic Park surf park this week, marking another milestone in the project’s construction. A grand opening is planned ...

Combining wind turbines with wave, solar and tidal devices on shared platforms reduces construction costs, improves stability and generates more reliable power, according to researchers from the ...

One key to harvesting the ocean’s clean energy—at least a little of it—may lie in static electricity. A team of researchers in Portugal has now successfully used it to run small generators inside a ...
