(NL1006933-C2)   NOVELTY - Provides a container formed in two parts. The first part (4) is connected to the frame, and the second part is displaceable in the vertical direction relative to the first. An energy converter (9) is used for energy conversion from the displacement of the second part. A device varies the volume of the space in the container intended for containing the gas.    USE - For converting energy from wave movement in water.    ADVANTAGE - Adjustment can be optimized for varying wavelengths and uses apparatus has a simple construction.
