Martin and Ottoway SurfWEC
The SurfWEC consists of two prime components; one freely moving component (float, point-absorber, “the bobber”) and one moored component (the variable-depth barge or “the base”). The SurfWEC system works by raising or lowering the base below the water surface until the passing waves achieve optimal height and surfing wave shape. The bobber is moved by these surfing waves and the wave energy is converted to electricity using a regenerative braking system inside the base and power takeoff system in the float. The SurfWEC system causes the bobber to move back and forth 10 to 30 meters per wave in average conditions (5 to 10 second period waves) where the bobbers in other existing WEC systems
