Tidal Turbine
Bristol, UK firm Marine Current Turbines successfully installed a 1.2MW turbine in Northern Ireland in the fast moving Strangford Narrows. This is the largest tidal harvest turbine installed to date (not including the tidal barrage systems that have been in use for some time in France for instance.)
MCT has plans for a 10.5MW project in conjunction with EDF off the coast of Wales scheduled to come online in 2012.
