A method for painting a component, in particular for painting a motor vehicle body component, with a decorative layer is provided. The decorative layer may be a decorative strip, a graphic element, a contrast surface or a pattern. The method includes applying a base coat layer, applying a decorative layer, which is within a decorative region with a limited surface area, to the component, and drying a limited drying region of the component, which drying region comprises at least part of the decorative region.

There is disclosed a desalinization apparatus, and methods related to desalinization. In an embodiment, a desalinization apparatus includes at least one port for receiving airflow therethrough, at least one port for receiving salt water therethrough, at least one output for providing outflow of pure water vapor, and at least one output for proving outflow of a mixture of water, salt and air; and a plurality of chambers for evaporating the salt water into the airflow, at least one of the chambers forming a plurality of ports arranged in a plurality of rows. In an embodiment, a method includes providing airflow to a desalinization apparatus; providing salt water to the desalinization apparatus; forming a vortex in the airflow to evaporate water vapor from the salt water; and providing the water vapor in the airflow to a condenser so as to obtain pure water.

The invention provides a method and apparatus for purifying water. The apparatus includes a water still for receiving water and a hot air maintained in a heat-exchanging relationship to obtain a hot water and a cold air. The apparatus also includes one or more water purification units configured to receive the hot water from the water still in which the hot water is further heated using thermal energy received from one or more thermal energy sources to obtain steam and waste matter. A water purification unit of the one or more water purification units includes a waste matter remover for removing the waste matter from the water purification unit. The water still includes a heat-exchanging unit configured to receive the steam from the one or more water purification units. The steam received at the heat-exchanging unit is condensed to obtain purified water within the heat-exchanging unit using the cold air.

The present disclosure relates to a biocide generating system for inhibiting bio-fouling within a water system of a watercraft. The water system is configured to draw water from a body of water on which the watercraft is supported. The biocide generating system includes an electrode arrangement adapted to be incorporated as part of an electrolytic cell through which the water of the water system flows. The water system is configured such that biocide treated water also flows to one or more components of the water system that are positioned upstream of the electrode arrangement.
