Abstract

Föreliggande uppfinning avser en turbinkonstruktion för turbiner med självsvängande turbinblad för användning i applikationer där flödet i turbinen byter riktning (oscillerar) som t.ex. i vågenergibojkonstruktioner som utvinner sin kraft genom turbiner som oscillerar i vattnet med utnyttjande av ytvattnets sjöhävning. Därtill avser uppfinningen vågenergibojkonstruktioner med uppfinningens turbin (kallad Loqvist-turbinen) samt en princip för anläggande av och förankring av vågenergikraftverk som sammansätts av oscillerande turbiner under flytelement.
