The invention relates to an auxiliary hydrogen system 20 for propulsion of a sailing boat 18. The system comprises: an electric navigation motor 22; an alternator 24; a propeller 26 with variable-pitch folding blades; drive means 28 for the propeller; a desalination unit 30 for intaking sea water and producing demineralized water; an electrolysis unit 32 for intaking demineralized water and producing hydrogen and oxygen in gaseous form; a main tank 34 for storing the hydrogen at low pressure; a hydrogen distribution circuit; at least one fuel cell 36 for converting the hydrogen into electric energy; and means 38 for electrically connecting the system to a permanent electricity network at the port. The propeller blades are designed to assume three different configurations: a configuration for recharging the system during sailing where the propeller blades assume a turbine configuration; a sailing regatta configuration where the propeller blades assume a folded-up configuration; and a motor navigation configuration where the propeller blades assume a propulsive configuration. Moreover the propeller drive means are designed alternatively to: connect the propeller to the alternator, thus defining the sailing recharging configuration; connect the propeller to the navigation motor, thus defining the motor navigation configuration; or keep the propeller mechanically disconnected, thus defining the sailing regatta configuration. The invention also relates to a sailing boat 18 comprising the system described above.
摘要:
The stable floating platform is constituted from (as shown in fig.l) four peripheral floaters (2) and one central (1) connected to each other with tubular grid (3). On top of the central floater a metal tower (4) is supported, with a wind generator (5). In the interior of the central floater (as shown in fig.2) a desalination unit (6) is installed with the essential equipment, the batteries and the control equipment (7). The peripheral floaters have the ability to store and input - output water, altering in this way the natural frequency of the structure (platform), avoiding thus resonance with the sea waves. The control of the water is made with valves that feed compressed air into the compartment that contains water, regulating thus the volume of the water in the cylinders. The floating structure presents only limited oscillations under sea waves and so it is possible for the wind generator (and/or the desalination unit) to operate on it.

An desalination apparatus 1 is towed behind a yacht (Y) on a high strength tube (2). An impeller (6) drives a high pressure pump (14) which draws sea water into the housing (5) where it is filtered and then pumped into a high pressure chamber (10) containing a reverse osmosis (RO) membrane (11). The pump (14) provides the energy for permeation in the RO membrane. Permeate flows into a central duct (12) and out into the tube (2) for delivery to the yacht. No yacht power plant is required and no environmental pollution is generated.

Die Erfindung betrifft ein Schiff, vorzugsweise Fahrgastschiff oder dergleichen Seeschiff, mit mindestens einer insbesondere für den Schiffsantrieb bestimmten Kraftquelle und mit wenigstens einer Anlage zur Nutzung von Abwärme sowie mit mindestens einer Kältemaschine, bei dem zumindest eine der Kältemaschinen als Absorptionskältemaschine ausgebildet ist und abwärmeseitig an eine Kraftquelle angeschlossen ist. Diese Absorptionskältemaschine weist wenigstens eine abwärmeseitig abgehende Abwärmeleitung auf, wobei mindestens eine der Abwärmeleitungen der Absorptionskältemaschine mit zumindest einer der Anlagen zur Nutzung von Abwärme verbunden ist. Als Anlage zur Nutzung von Abwärme ist insbesondere eine thermische Entsalzungsanlage für Seewasser vorgesehen, welche mit der Restwärme der Absorptionskältemaschine betreibbar ist.
摘要:
The present invention relates to a method and apparatus for having a integrated fluid media filtration and membrane unit within the hull of a sea-bound vessel. The vessel's propulsion will drive the flow of seawater into the media filtration and membrane unit. Multiple stages of the passing of seawater via the membrane and/or a series of progressive membranes can be implemented to reduce the level of sodium chloride present in seawater to desirable specifications.

Provided are a desalination plant mounted on a barge and a method for placing the same. The barge is constructed to float on the sea, and the desalination plant is constructed to draw seawater from the sea and desalinate the seawater into freshwater. The desalination plant mounted on the barge is placed on a heavy lift vessel, tugged by a tugboat, and installed in the seashore of a water-scarcity area or island area.
