  • Fig. 15 there is a top view of the lower shell 106 and showing the positioning of the various water chambers 114.
  • the is a float 144 that is contained within each of the water chambers 114 and which can rise and fall with the surface of the water as it rises and falls within the water chambers 114.
  • the water chambers 114 affixed to the peripheral area of the lower shell 106 so as to be vertically located approximately at the surface of the ocean when the apparatus 80- is situated in its working location atop of he surface of the ocean.
  • Fig. 18 there is a enlarged side view one of the typical water chambers 114 having a float 144 contained therein that rises and falls with the surface of the ocean. As can be seen, that rise and fall causes the air trapped within the upper area 146 of the water chamber 114 to be compressed and expanded and, as in the prior embodiment, creates a reversing flow of air in the passageway 146 and, in turn, operates the air turbine 148 that is in communication with that passageway 146.
  • the air turbine 148 will rotate as the air passes through the air turbine and may be of the same type of air turbine as described with respect to the first embodiment, that is, a pair of monoplane wells turbines that are self-rectifying and thus are driven in the same direction regardless of the direction of the air flow.
  • An additional supply of air for the air turbine 148 is supplied by an air pumping system that is comprised of a lever arm 150 having one end thereof affixed to the moving float 144 by means of a connecting arm 152 such that the lever arm is pivotally mounted and rocks as the float moves upward and downward within the water chamber 114 as the surface of the water also moves upward and downward.
  • the other end of the lever arm 150 is affixed to an air pump 154 of conventional design that pumps air by a mechanical reciprocating motion and thus, as the lever arm 150 rocks as a result of the float 144 moving up and down within the water chamber 114, the air pump 154 provides an additional supply of air via an outlet pipe 156 to the air turbine 148 to recover additional power from the natural motion of the surface of the ocean.

Abstract

La présente invention concerne un appareil de production d'énergie flottant placé sur la surface de l'océan, qui peut recevoir le mouvement des vagues autour de toute sa périphérie. L'eau est dirigée vers une rampe se rétrécissant vers l'intérieur jusqu'à un endroit surélevé depuis lequel elle peut ensuite retomber dans une turbine hydraulique sous l'effet de la gravité. La turbine hydraulique convertit cette énergie en un mouvement rotatif destiné à entraîner un dispositif de génération électrique. L'appareil permet en outre de capter l'eau une deuxième fois dans une admission d'eau placée le long de la rampe qui se rétrécit et d'utiliser cette eau de retour pour maintenir la turbine hydraulique en fonctionnement. L'invention comprend également une turbine de tempête capable de capter l'énergie des grandes ondes d'orage et de convertir cette énergie en énergie électrique.
