TL;DR: In this article, the length of the tubular structure was 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 tube increases from a minimal value until L reaches an optimal value; and (b) the energy efficiency decreases as L is increased beyond the optimal value due to the increased mass of the water that the tube and the piston have to move.
Abstract: A wave energy converter (WEC), for use in a body of water of depth Dw, includes a tubular structure and a piston within the tubular structure where the relative motion between the piston and the tubular structure is used to generate 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 have to move.

TL;DR: In this paper, a longueur (L) de la structure tubulaire peut etre choisie afin de posseder une valeur predeterminee basee sur le fait that: (a) le rendement energetique genere augmente avec la longueure 'L' de la structural tubulaite a partir d'une valeure minimum jusqu'a ce que L atteigne une vareur optimale, and (b) le règende decroit lorsque
Abstract: L'invention concerne un convertisseur d'energie des vagues, destine a etre utilise dans de l'eau de profondeur Dw, comprenant une structure tubulaire et un piston (12) a l'interieur de la structure tubulaire, le mouvement relatif du piston (12) par rapport a la structure tubulaire etant utilise afin de produire (42) de l'energie electrique. La longueur (L) de la structure tubulaire peut etre choisie afin de posseder une valeur predeterminee basee sur le fait que: (a) le rendement energetique genere augmente avec la longueur 'L' de la structure tubulaire a partir d'une valeur minimum jusqu'a ce que L atteigne une valeur optimale, et (b) le rendement decroit lorsque L depasse la valeur optimale en raison de la masse d'eau, dont la quantite a augmente, que doivent deplacer la structure tubulaire et le piston (12).
