An apparatus for converting wave energy into electricity comprises an inlet, an inlet chamber coupled to the inlet and arranged to allow water to flow from the inlet to the inlet chamber. The inlet and inlet chamber form an oscillating water column. An outlet for connection to electricity generating means and an outlet chamber in the form of a reservoir coupled to the outlet are arranged to allow water to flow to the outlet. Between the oscillating water column and reservoir, a gas chamber is arranged such that that a gas in the gas chamber may be trapped by water in the inlet chamber and the outlet chamber. A weir is arranged in the gas chamber such that water may flow over the weir. Periodic variation in pressure of water at the inlet causes water to periodically oscillate in the oscillating water column transmitting pressure to the reservoir by compression of gas in the gas chamber forcing water to pass through the outlet. The outlet chamber is arranged between the inlet and inlet chamber, thereby allowing a larger than normal radius of curvature of the flow path and avoiding detrimental effects such as vortex shedding. |
