RENEWABLE ENERGY: Smart Power Buoy - Wave Power Expands Recharge at Sea Possibilities

From powering sensor systems to recharging autonomous vehicles to feeding the power grid, Resen Waves is making step changes in the renewable wave power market. Roland Boysen, CCO, discussed the technology and the potential with MTR.While generations of innovators have attempted, to varying degrees of success, to harness the tremendous renewable power potential of waves, the Danish company Resen Waves contends it is able to do just that, in a scale to remotely power sea-based instruments and vehicles, and eventually all the way up to entire cities.The Resen Waves Smart Power Buoy is designed to

The Value of Friends in “High-Latitude” Places

Who do you call when you need a job done on short notice, in total darkness, under 100-percent ice cover, thousands of meters at the bottom of the sea? In the case of the U.S. Office of Naval Research (ONR), you call your friends in Norway. That is exactly what the Chief of Naval Research Rear Admiral Lorin C. Selby did when he enlisted the help of the Norwegian Coast Guard icebreaker and offshore patrol vessel, the CGV Svalbard, to retrieve oceanographic moorings containing irreplaceable data. The work supported the Coordinated Arctic Acoustic Thermometry Experiment (CAATEX), an important international

“In developing a floating system, the real challenge is dealing with the huge loads through the mooring system. To give you an idea, two of our turbines produce the same thrust as an F-35 fighter jet on full afterburner. So you take our new six-turbine platform, and that's like taking three F-35s, telling the pilots hit full throttle, and putting that on a leash.”

Major changes are occurring in the ocean. Climate change and subsequent melting sea ice are not necessarily good changes. Why are acoustic Doppler current profilers an invaluable tool to get a complete picture of the Arctic’s changing wave conditions in the context of climate change?In the Arctic, the end-of-summer sea ice extent in 2020 was the second-lowest in the last 42 years.“The ice used to melt out in June or July.
