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

In the ocean they either settle out slowly, or can be transported rapidly by episodic turbidity currents – powerful underwater avalanches – that travel down submarine canyons to the deep seafloor (see the group’s earlier research in Environmental Science & Technology).
