British engines and power systems maker Rolls-Royce will test a one megawatt turbine to generate electricity from tidal power next year, Ric Parker, director of research and technology, said. “It’s a huge opportunity for the UK, we’re ideally positioned to lead on this because we have the resources all around us,” said Parker, referring to Britain’s location and long coastline which give it a big chunk of European tidal and offshore wind power.
