1. Schwimmende Flüssigbatterie, deren Elektrolytflüssigkeit aus Salzwasser bestehen kann.2. Bei Flüssigbatterien handelt es sich um eine Bauform von Energiespeichern, die elektrischen Strom in ihrem Speichermedium, welches in der Regel aus Salzwasser besteht, aufnehmen und wieder abgeben können. Stationäre Modelle mit kleiner Speicherleistung werden oft in Wohnhäusern installiert, in der Regel um Strom aus Photovoltaikanlagen, die direkt an der Immobilie verbaut sind, aufzunehmen, um diesen zeitversetzt wieder abgeben zu können. Es sind auch deutlich größere Anlagen bekannt, die im gewerblichen Bereich eingesetzt werden oder als Speicher für größere Wohnanlagen dienen. Ihre Verbreitung ist trotz vieler Vorteile auf Grund der höheren Entstehungskosten, die im Wesentlichen aus der geringen Speicherkapazität des verwendeten Salzwassers als Speichermedium resultieren, nicht besonders ausgeprägt.2.1 Um kostengünstige Flüssigbatterien bereitstellen zu können, wird eine schwimmende Flüssigbatterie, deren Elektrolytflüssigkeit (7) aus Salzwasser bestehen kann (1) Vorgeschlagen, die in einer reißfesten, wasserundurchlässigen Batteriehülle (3) untergebracht ist und in einem geeigneten, bestehenden oder dafür neu geschaffenen Gewässer (10) schwimmend so positioniert wird, dass der Innendruck in der wasserundurchlässigen Batteriehülle (3), der mehrheitlich durch die entsprechende Menge an Elektrolytflüssigkeit (7) erzeugt wird, von dem Außendruck des Gewässe

An object of the present invention is to provide a construction method for a floating wind power generation facility which is less susceptible to wind and waves when towing. A provisional assembly (1a) is assembled on land. The provisional assembly (1a) includes a base part (8) of a floating body (2) and a provisionally mounted member (6, 13, 16) disposed at a position different from a position at completion. After assembly of the provisional assembly (1a), the provisional assembly (1a) is launched. After being launched, the floating wind power generation facility under construction is towed to its installation position, and the provisionally mounted member (6, 13, 16) is disposed at the position at completion. Since the provisional assembly (1a) is shorter in length in the up-down direction than the completed floating wind power generation facility, the provisional assembly (1a) is less susceptible to wind and waves when towed.

Motion of a floating body is damped by anchoring a piston with a sea anchor to restrict movement of the piston, permitting greater movement of a chamber that surrounds the piston and is fixed to the body, but braking the resulting relative movement between the chamber and the piston by displacement of fluid in the chamber. Thus, a motion damper has a brake structure that comprises a submerged sea anchor suspended in a water column and connected to a piston. The piston is movable within an elongate chamber that is in fixed relation to the floating body and that contains a fluid such as water.
