Offshore hydrokinetic energy conversion for onshore power generation
Design comparisons have been performed for a number of different tidal energy systems, including a fully submerged, horizontal-axis electro-turbine system, similar to Verdant Tidal Turbines in New York’s East River, a platform-based Marine Current Turbine, now operating in Northern Ireland’s Strangf...
