This paper focused on introducing the new-concept wave energy converters for the extraction of energy from waves and some results of an experiment on concentric two-body system composed of the hollow exterior cylinder and interior cylinder floating inside the exterior cylinder. Electricity is generated from the Power take-off system using relative vertical motion of two concentric cylinders. In order to maximize the relative vertical motion, the resonance, so called piston mode resonance, was used. The model test contained a series of experiments concerning two concentric cylinders arrangements(radius and draft). The heave motion responses of two concentric cylinders have been recorded using accelerometer, and compared with analytical prediction. Representative experimental data and their comparisons with analytical predictions will be presented in this paper, together with the description of the experimental test.
