Maximising wave power Maximising wave power

Technology for extracting power from waves is still very much at the developmental stage, but it is already well known that devices in which the waves set up an oscillation work better if they can achieve resonance with the ‘forcing’ impulse i.e. the waves. In fact, exploiting the resonance phenomenon can amplify harvested wave power several times over what it would otherwise be. George Marsh investigates.
