The invention relates to a device for collecting energy from water waves, comprising an extended length channel provided with a long shore-facing wall, a long sea-facing wall, and a remote end wall all extending substantially above high water level, and a proximate end wall forming a fixed lower dam having an upper edge approximately level with low water level. The shore-facing wall of the channel being sloped in a shoreward direction so that the upper open edge of the wall is nearer the shore than the lower edge of the wall. The sloped wall being impacted by waves having entered the channel and retaining water of the waves at a raised level above sea level. Inside the channel, the long sea-facing wall being pierced by multiple one-way apertures extending substantially over the complete area of the sea-facing wall, each one-way aperture being closed by an attached shutter unit opening inwards under pressure of incoming water waves and closing after the entry of the waves to maintain the raised water level in the channel; |
