2.7.3 TurbineTurbines are driven by either water or air, and are coupled to a generator (Drew, 2009). Anadvantage of turbines is they can offer regulation over wave power variation by controllingthe volume of the fluid (Brooke, 2003). WEC devices require special bidirectional turbines,such as the Wells Turbine. Oscillating water columns and overtopping wave devices usebidirectional turbine systems.2.7.4 Rotary GeneratorRotary generators have potential use when coupled with turbines. These types of devices arepopular with wind energy, and have thus been extensively studied for renewable energysources (Drew, 2009).30
