ABSTRACT:
A wave-activated power generating apparatus includes a generally L-shaped duct including a vertically extending portion and a horizontally extending portion and a floatable main body fixedly attached to the duct. The floatable main body is provided such that it is located rearwardly of the vertically extending portion of the duct when the apparatus is set in position floating on the water surface. The horizontally extending portion is in fluidic communication with the vertically extending portion and has an open rear end which is submerged underwater in normal operating condition. Because of the particular arrangement of the main body with respect to the vertically extending portion of the duct, the apparatus is subjected to pitching motion vigorously, which allows to obtain an increased power output. In addition, the water column is ejected in the form of a jet stream in the rearward direction, which contributes to mitigate the mooring force requirements.
