Abstract

The flow accelerator of sea currents consists of wings rotating around a vertical shaft, each one composed of two half-wings with the shaft between them and equipped with one-direction flat disks functioning as valves (6). The rotation perimeters ofthe wings are connected with gearwheels or wheels connected between them by driving belts, which -interconnected in pairs and rotating in opposite directions- force the wings to rotate coordinately, so that these in combination always present the maximum area, i.e. resistance to the current (6). A smaller wheel ( 11 ) is connected with one of the wheels of the pair. Afterwards, the small wheel transmits its motion to a larger wheel ( 11A ) connected to and rotating around it. The result is thatthe peripheral velocity of the larger wheel is now much greater than the velocity which it would have if it were rotated directly by the current. This acceleration is possible since - except of the great wheels 1 and 2 - the others are flat disks rotating parallel to the current (11, 12, 13) so they don't present hydrodynamic resistance. This procedure is repeated when the last larger wheel transmits motion to another small wheel which again -during another acceleration phase- activates anotherlarger wheel rotating around it. Similar phases of acceleration -until complete exploitation of the dynamic energy of the current- finally activate a generator ( 7 ). The whole system may perform the rotations with rollers on circular monorails positioned on a stable frame lying on a scaffold or on a anchored float, depending on the depth of the sea.
