US Patent 10161379 Coastal protection and wave energy generation system

This invention relates to a wave energy generator for a coastal protection system. The wave energy generator includes a base structure arranged in a body of water and configured to protect a portion of a coastline against incoming waves. The base structure has a foundation located on a floor of the body of water and a wall extending from the foundation to a point above a highest predicted height of the waves. At least one duct is associated with the base structure for receiving an oscillating water column from the body of water. The oscillating water column oscillates in response to wave action of the incoming waves and the duct forms part of an energy extraction system for capturing energy from the incoming waves.
