Wave Power

CorPower Ocean's wave power-harnessing buoys utilize a geared drivetrain instead of hydrau...

Harnessing wave power can be a tricky business. It's one thing to build a device that simply moves up and down with the waves, but another to build one that's efficient enough to be cost-effective. Swedish company CorPower Ocean claims to have done just that, however. Its wave energy converter buoys reportedly generate five times more energy per ton of device, at a third the cost of other wave power systems.  Read More

The fishing boat, with its four chambers visible at the front

An old fishing trawler has been given new life in Norway, where it's now anchored offshore in the Stadthavet area and serving as a wave power plant. It's part of a project which ultimately calls for larger, purpose-built vessels to convert wave motion into electricity.  Read More

The Odyssée system uses wave power to churn out clean drinking water

Watching on as the waves crashed against the cliffs of South Corsica, France, mechanical engineer Dragan Tutić knew some were already drawing on power from the ocean to generate electricity. But a possible use for all that motion in the ocean that had been largely unexplored, as far as he knew, was turning its salty seawater into the fresh, drinkable variety on the spot. In the following two and a half years, Tutić and his team designed and tested a prototype for a wave-powered desalinator, and now hold hopes of deploying the system in regions where water scarcity threatens the survival of coastal communities.  Read More

WaveNET - a floating, flexible, modular and massively scalable wave power generation idea ...

Scotland's Albatern is putting a new, modular spin on renewable energy generation. WaveNET is a scalable array of floating "Squid" generator units that harvest wave energy as their buoyant arms rise and fall with the motion of the waves. Each Squid can link up to as many as three others, effectively creating a large, floating grid that's flexible in every direction. The bigger this grid gets, the more efficient it becomes at harvesting energy, and the more different wave movements it can extract energy from. Albatern's 10-year target is to have 1.25 kilometer-long floating energy farms pumping out as much as 100 megawatts by 2024.  Read More

A rubber mat forms the 'carpet,' and sits atop a grid of hydraulic actuators, cylinders an...

Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths.  Read More

The Wind Clapper and Power Wing, converting rising and falling waves into energy

Israel's Eco Wave Power (EWP) has just signed a memorandum of understanding agreement with the Ocean University of China to fund and test its first commercial scale Wind Clapper and Power Wing wave energy generation system.  Read More

Wave Glider robots are being deployed as part of an extensive marine life tracking network...

If you’ve ever sat in a beach-side coffee house wondered if there was a white shark in the vicinity, then wonder no more because now there’s an app for that. A team of Stanford University researchers lead by Prof. Barbara Block is deploying a fleet of static buoys and Wave Glider robots to turn the waters off the coast of San Francisco into a huge Wi-Fi network to track tagged fish and animals. This will allow scientists to better understand sea life movements, but the project also includes offering a free app to the public that will allow them to track northern California white sharks on their tablets and smartphones.  Read More

A wave energy project off the coast of Victoria, Australia will comprise 45 PowerBuoys (Ph...

Lockheed Martin has teamed up with Ocean Power Technologies (OPT) to develop one of the world’s largest wave energy generation projects. The 19-megawatt project to be located off the southern coast of Australia in Portland, Victoria, will be built around OPT’s PowerBuoy technology that has previously been trialed by the U.S. Navy off the coast of New Jersey for powering remote sea-based radar and communications systems.  Read More

Eco Wave Power has revealed the construction and testing of a medium-scale version of its ...

Eco Wave Power has reported the completion of a medium-scale version of its Wind Clapper and Power Wing wave energy generation system. The company has released a video showing the system in action and is currently undertaking testing and evaluation before work begins on the construction of the first commercial scale EWP wave power plant.  Read More

Six different float designs undergoing tests in the wave pool of the Institute for Hydrome...

Israel's Eco Wave Power is just entering the second phase of proving its new wave energy harvest and conversion system that's claimed to produce cheaper energy than existing coal-fired power plants. Energy is captured by the influence of rising and falling waves on two proprietary float designs called the Wave Clapper and Power Wing, which are installed on existing, stable structures. The floats are said to be capable of gathering energy from both high and low waves, which is fed through undersea cabling to a land-based power plant for conversion to usable electricity.  Read More
