Abstract
In the present work, a unique design using a direct mechanical drive based power takeoff system is proposed, designed, fabricated and tested for a point absorber. The power take-off mechanism in the design consists of rack and pinion arrangement, which converts the bidirectional reciprocating motion to unidirectional rotation. This mechanism is fixed on top of an oscillating buoy. The model is tested in a 4m wave flume to measure various parameters like Response Amplitude Operator of the buoy, capture width, electric power output and absorption efficiency for different wave height and periods. The model is also tested for friction outside the flume. The experiments revealed some promising results that can be taken forward for further investigations.
