A wave energy converter (WEC), for use in a body of water of depth Dw, includes a tubular structure and a piston (12) within the tubular structure where the relative motion between the piston (12) and the tubular structure is used to generate (42) electric power. The length (L) of the tubular structure may be selected to have a predetermined value based on the fact that: (a) the efficiency of the power generated by WEC increases as the length "L" of the tubular structure increases from a minimal value until L reaches an optimal value; and (b) the efficiency decreases as L is increased beyond the optimal value due to the increased mass of the water that the tubular structure and the piston (12) have to move.

L'invention concerne un convertisseur d'énergie des vagues, destiné à être utilisé dans de l'eau de profondeur Dw, comprenant une structure tubulaire et un piston (12) à l'intérieur de la structure tubulaire, le mouvement relatif du piston (12) par rapport à la structure tubulaire étant utilisé afin de produire (42) de l'énergie électrique. La longueur (L) de la structure tubulaire peut être choisie afin de posséder une valeur prédéterminée basée sur le fait que: (a) le rendement énergétique généré augmente avec la longueur "L" de la structure tubulaire à partir d'une valeur minimum jusqu'à ce que L atteigne une valeur optimale, et (b) le rendement décroît lorsque L dépasse la valeur optimale en raison de la masse d'eau, dont la quantité a augmenté, que doivent déplacer la structure tubulaire et le piston (12).
