Abstract

Det beskrives en bølgeenergiomformer som omfatter to bøyer, en først som er generelt flat og stiger opp og ned i fase med passerende bølger på et vannlegeme, og den andre er langstrakt og stiger opp og ned ute av fase med de passerende bølgene. Fortrinnsvis er den første bøyen ringformet med en sentral vertikal åpning derigjennom, og den langstrakte bøyen, med en vektet bunnende, strekker seg vertikalt gjennom den sentrale åpningen på den første bøyen. De to bøyene beveger seg derfor ute av fase med hverandre, og følgelig tilveiebringer en relativt stor relativ bevegelse mellom de to bøyene som gir økning av høy effektiv energiomforming. Hver bøye fungerer som en "jord` for den andre, og derfor unngås behovet for å ankre bøyene til bunnen på vannlegemet.A wave energy converter is described which comprises two buoys, one first being generally flat and rising up and down in phase with passing waves on a water body, and the other being elongated and rising up and down out of phase with the passing waves. Preferably, the first bend is annular with a central vertical opening therethrough, and the elongated bend, with a weighted bottom, extends vertically through the central opening of the first bend. The two buoys therefore move out of phase with each other, and consequently provide a relatively large relative movement between the two buoys which gives rise to high efficient energy conversion. Each buoy acts as a "ground" for the other, thus avoiding the need to anchor the buoys to the bottom of the water body.
