The lush hills of Strangford Lough are truly a place of magic scenery. Portaferry, a small fishing village, is located one hour’s drive from Belfast in Northern Ireland, and is today perhaps most famous for being close to the location where blockbuster Games of Thrones is filmed. In this idyllic fishing village, struggling with a high unemployment rate and a diminishing population, something new and prosperous is growing. Looking out over the calm waters of Strangford Lough, one could hardly believe that under the ocean surface — that electricity can be produced.
