  • Patent number: 4446378
    Abstract: The subject-matter of the present invention is a system for the generation of electrical energy by utilizing the kinetic energy of seawater, comprising a floating body exhibiting two floating supports (1) connected by a lower platform (2), a main deck and a large impeller (5) arranged between them and having a horizontal axis (12). The impeller axis is carried by vertical platelike supports (4) which divide the impeller vanes into several sectors. The rotary movement of the impeller is transmitted to a machine park (19-22) located on the main deck (3) for the generation of electrical energy. Despite its large dimensions the system according to the invention is distinguished by its high stability (FIG. 7).

  • Patent number: 4396843
    Abstract: The subject-matter of the present invention is a system for the generation of electrical energy from wind energy consisting of a domed building (3) and a large dimension impeller (5) mounted thereupon. The shape of the impeller (5) is adapted to the curvature of the domed building. It is supported on the surface of the domed building via rollers (71) and rails (16). In the region of the rollers (71) and rails (16) members for braking and holding the vanes are provided. The rotary movement of the impeller is transmitted via a central axis (6) to a machine park (12) to (15) housed in the interior of the domed building (3) so as to generate electrical energy. The system according to the invention is distinguished by its excellent stability despite its large dimensions; cf. FIG. 2.
