<p>A method of distilling water from sea water, the method comprising the steps of : a) providing an elongate sea water conduit (12) and an elongate distilled water conduit (14) which is spaced from the sea water conduit (12), the sea water conduit (12) and the distilled water conduit (14) being fluidly interconnected by a vapour passage (16); b) pumping sea water into the sea water conduit (12) to a level below an inlet (66) of the vapour passage (16); c) heating the sea water in the sea water conduit (12) using solar energy via an opaque solar collector (22) forming at least part of the sea water conduit (12) such that the sea water therein is in direct contact with the solar collector (22) so as to be heated by conduction; d) feeding saline effluent through an effluent conduit (34) in the sea water conduit (12) and in contact with the sea water in an upstream direction of the sea water conduit (12) so that the saline effluent further heats the sea water; e) collecting distilled water in the distilled water conduit (14) as condensate which has passed as water vapour through the vapour passage (16) from the heated sea water conduit (12); f) channelling the distilled water in the distilled water conduit (14) to an outlet for use. Apparatus is also provided.</p> |
