...In August, the world's largest tidal-current generator will be installed on Northern Ireland's Strangford Lough and, next year, ScottishPower will start testing an underwater turbine in the Pentland Firth itself.
ScottishPower believes its system could generate up to a gigawatt (GW) of electricity - equivalent to all of Scotland's wind farms put together, or the power produced by the Hunterston B nuclear power station.
