Technology Description The AWS wave energy converter is a cylindrical chamber moored to the seabed. Passing waves move an air-filled upper casing against a lower fixed cylinder, with up and down movement being converted into electricity. As a wave crest approaches, the water pressure on the top of the cylinder increases, and the upper part or 'floater' compresses the gas within the cylinder to balance the pressures. The reverse happens as the wave trough passes and the cylinder expands.
Power Transfer Method The relative movement between the floater and the lower part, or silo, is converted to electricity by means of a hydraulic system and motor-generator set.
