Pelamis wave power, diagram
{"Image ImageDescription": "Pelamis wave power. Diagram showing the principles of the Pelamis system of generating electricity from wave energy. This uses large floating sections with articulated joints between them. At the joint are hydraulic rams hat push fluid through a closed loop system as the joint bends back and forth. The fluid passes through a turbine, generating electricity each time the joint bends or straightens.", "Image XResolution": "72", "Image YResolution": "72", "Image ResolutionUnit": "Pixels/Inch", "Image YCbCrPositioning": "Centered", "Image Copyright": "Science Photo Library"}
