Abstract: A combined offshore system for generating electricity includes of an offshore windmill unit with a generator for extracting power from wind and transferring it into electricity, a electricity export cable connected to the windmill for exporting produced electricity to offshore or onshore consumers, and at least one offshore wave power unit for extracting power from waves. This offshore wave power unit is characterized in that electricity produced by the wave power unit is transferred via the same electricity export cable as the electricity generated by the windmill unit.

Abstract: A floating energy generating device includes at least two wind turbines mounted on a floating open structure, the floating open structure being moored to the seabed with a mooring system, each wind turbine featuring in operation mode a blade and rotor part mounted at the top of a tower and being connected via a cable to a central control power electronic unit on the floating open structure, the central control power unit being connected to a submerged high voltage power export cable for exporting the electricity generated by the at least two windmills, characterized in that the floating open structure being connectable to or disconnectable from the mooring system and that when disconnected from the mooring system, the center of gravity of the floating open structure is at or below its center of buoyancy.

Abstract: Systems are described for obtaining energy from water movements in shallow waters, using panels (4) that are pivotally mounted (13) near the sea floor in shallow water and that extend up to the sea surface, or that are pivotally mounted above the sea surface and extend down into the sea. As water near the sea surface moves in ellipses (48), or largely back and forth, the panel pivots back and forth. A cylinder (8, 18) with one end (7?) mounted on a stationary base and an opposite end (7) connected to the panel, carries at least one sheet (70) of elastomeric material that has electrodes (72, 74) at its opposite faces, with an electrical charge between the electrodes. As the panel pivots back and forth, the sheet is repeatedly stretched and relaxed to vary the voltage between the electrodes in order to generate electricity. A cylinder (8) can be used whose ends move toward and away from each other, or a cylinder (18) can be used whose ends pivot about a cylinder axis relative to each other.
