Abstract
This invention relates to a device and method for extracting energy from surface waves in a body of water, for example, the sea. A wave energy device (1) for extracting energy from surface waves in a body of water includes an elongate and flexible tubular body (2) having an outer wall (4) and within the outer wall a channel (6) that extends along the length of the tubular body (2). The device is positioned in a body of water so that, in use, the elongate body (2) extends along the water surface (15) in the direction of surface waves with water contained within the channel being driven to form a series of bulge waves that travel along the length of the channel as the tubular body flexibly follows the movement of the waves. The device harnesses energy from the bulge waves for providing useful power.
