Abstract

Un système houlomotrice comprend deux flotteurs. Le premier est généralement plat et monte et descend en phase avec le passage des vagues de surface d'un plan d'eau et le second est allongé et monte et descend en décalage avec le passage des vagues. Le premier flotteur est de préférence annulaire et est traversé par une ouverture verticale centrale, et le flotteur allongé, à extrémité inférieure lestée, s'étend verticalement dans l'ouverture centrale du premier flotteur. Les deux flotteurs bougent ainsi en décalage l'un par rapport à l'autre, ce qui produit un mouvement relativement important entre les deux flotteurs et induit ainsi une conversion d'énergie élevée. Chaque flotteur sert de "base" à l'autre, ce qui supprime la nécessité d'ancrage des flotteurs au fond du plan d'eau.
