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

Shrinking Sea Meadows Store More Carbon Than Forests. Scientists Race to Track What’s Left

Hundreds of miles from the nearest shore, ribbon-like fronds flutter in the ocean currents sweeping across an underwater mountain plateau the size of Switzerland.A remote-powered camera glides through the sunlit, turquoise waters of this corner of the western Indian Ocean, capturing rare footage of what scientists believe is the world’s largest seagrass meadow.Human activity is helping destroy the equivalent of a soccer field of these seagrasses every 30 minutes around the world, according to the U.N. Environment Program (UNEP). And scientists are now racing to take stock of what remains.“Th

“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.”
