Wave Power

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

bioWAVE is a wave power system, inspired by the swaying motions of kelp plants

Anyone who has ever been scuba diving in a bull kelp forest will tell you - the stuff does not stand still. The marine aquatic plant consists of a long skinny-but-tough stem (or stipe) that is anchored to the sea floor and topped with a hollow float, from which a number of "leaves" (or blades) extend to the surface. The result is a seaweed that extends vertically up through the water column, continuously swaying back and forth with the surging waves. The researchers at Australia's BioPower Systems evidently looked at that kelp, and thought, "what if we could use that swaying action to generate power?" The result was their envisioned bioWAVE system, which could soon become a reality, thanks to a just-announced AUD$5 million (US$5.1 million) grant from the Victorian Minister for Energy and Resources.  Read More

LEAP Autonomous PowerBuoy deployed off New Jersey (Image: Michael Smith, Rutgers Universit...

Maritime surveillance and monitoring systems that require remote power at sea often rely on diesel generators that need frequent maintenance and fuel replenishment. Now New Jersey-based wave energy company Ocean Power Technologies (OPT) has commenced sea trials of an autonomous wave energy device that provides clean energy for sea-based radar and communications systems in remote ocean locations and in all wave conditions.  Read More

A proposed wave-power system could be installed on ships, which would regularly return to ...

Why don’t we have stationary commercial fishing platforms that are anchored offshore, where they sweep the waters with their nets, sending the captured fish back to shore through a pipeline? Well, because it’s simpler and more efficient to send fishing boats out to catch the fish and bring them in. Thinking along those same lines, the Fraunhofer Center for Manufacturing Innovation has proposed a ship-mounted renewable energy-harvesting system, that would be powered by the ocean’s waves.  Read More

The 1/9th scale version of the AWS III wave energy system at Loch Ness

Solar power might be stealing the limelight when it comes to the subject of renewable energy, but ocean waves are also seen as a great, largely untapped source of clean power. The latest news surrounding attempts to mine this potentially limitless energy source comes from Scottish marine energy technology developer, AWS Ocean Energy, which has started testing its new wave energy device in Loch Ness in the Scottish Highlands.  Read More
