A fleet of cutting-edge sea machines is using the power of the oceans to revolutionize the energy industry, and the innovative engineering behind these hi-tech behemoths could change the world. Located in Scotland's Orkney Islands, the European Marine Energy Centre (EMEC) tests marine renewable energy technology: tidal turbines (Scotrenewables SR-2000, Orbital 02, and Magallanes Renovables ATIR) and wave energy converters (Wello's Penguin).
