A floating wind turbine platform includes a floatation frame (105) that includes three columns (102, 103) that are coupled to each other with horizontal main beams (115). A wind turbine tower (111) is mounted above a tower support column (102) to simplify the system construction and improve the structural strength. The turbine blades (101) are coupled to a nacelle (125) that rotates on top of the tower (111). The turbine's gearbox generator and other electrical gear can be mounted either traditionally in the nacelle, or lower in the tower (111) or in the top of the tower-supporting column (102). The floatation frame (105) includes a water ballasting system that pumps water between the columns (102, 103) to keep the tower (111) in a 10 vertical alignment regardless of the wind speed. Water-entrapment plates (107) are mounted to the bottoms of the columns (102, 103) to minimize the rotational movement of the floatation frame (105) due to waves.

A versatile turbine suitable for both hydraulic and pneumatic applications. The turbine's blades are affixed to the inner surface of a cylindrical shell which is free to rotate about an outside supporting structure. Rotational energy is transferred from the outer surface of the rotating cylindrical shell, usually by means of a gear; however, there may be applications better suited for a pulley means of transfer. The vacant central axis of rotation can be closed, by incorporating taller blades to achieve a larger surface area, resulting in greater efficiency, or open, by means of shorter blades forming a hole with the distal edges of the blades, to allow for passing fish and or debris to safely exit. The preferred embodiment further includes a means for electricity generation, water purification, and hydrogen production.

It seeks to enhance the energy-capturing potential of air/water turbines, and hence expand the geography where they can be used. It is mainly represented by a device consisting of a vortex generator and a vortex accelerator.

(2) Induce suction that can be used to transfer momentum to the flow close to the surface of the blade. Specifically, the generated suction drives secondary fluid flow, which is used to enhance the aerodynamic characteristics of the turbine blades/wings, by doing the following: (1) Suppressing adverse pressure gradients, (2) Suppressing the stall or separation bubble, (3) Laminarize the flow over the blade or wing.

The invention relates to a rapid response method for the failure of a link between two routing domains in a packet-oriented network. Once the failure of a link has been identified, substitute routes are provided for the interrupted routes by the local selection of alternative routes and by the propagation of messages along the substitute routes. In contrast to conventional inter-domain protocols such as the BGP (Iborder gateway protocol) the transmission of messages and the associated modification to the routing only involves routing domains that lie along the replacement routes. In one embodiment, a network-wide propagation of messages takes place if the failure of the link represents a persistent breakdown. As a consequence, optimal routes are re-determined in the entire network. The invention provides breakdown compensation that is appropriate for temporary breakdowns and prevents instabilities that occur as a result of the use of conventional inter-domain protocols.

Wave energy conversion to produce electricity uses wave-engaging articulated, forward and after barges connected to a center inertial barge. A damper plate attached to the central barge minimizes heaving to increase stability. The barges use composite materials, steel or other materials that can withstand the impact and wear caused by a corrosive weather environment. A movable ballast weight in each barge adjusts the mass moment of inertia, and changes the natural pitching frequency. Electrical energy is generated from the motions of the barges and the movement of the movable ballast weights being converted by linear induction motor/generators and/or Pelton Wheel hydraulic systems connected to electrical generators. A dynamic computer control system controls the energy generating system to keep the forward/after barges and the movable ballast moving in phase with the wave excitation force. During dangerous wave action, the system is submerged and then re-surfaced when the waves have subsided.
