The invention relates to a seawater desalination method and device. The aim of said invention is to provide a seawater desalination method and device, which may operate by using renewable energies in a self-sufficient manner even in places of the earth, where no infrastructure in the form of mains cables or the like is available. Said aim is achieved, whereby the seawater desalination device comprises a reactor (1), hermetically sealed in relation to the atmosphere and at least mostly transparent, said reactor having an outlet (111) for humid air, on the upper face (11) thereof, and a water tank (121) on the lower face (12) thereof, which comprises at least one stirrer device (122) and/or an air supply (123), an inlet (124), for fresh seawater and an outlet (126), for highly-concentrated salt water, provided with a controllable valve (127), whereby said reactor (1) is connected to a descending pipe (2), carrying off humid air, by means of the outlet (111), said pipe opening out into a condensation chamber (3) in the deep sea water, which leads to an ascending pipe (4) or an ascending chamber (5). Said invention also provides a method, using said device, which comprises the steps of saturating the air with humidity, by foaming in the reactor (1), drawing off the air, saturated with humidity from the reactor (1), by means of the descending pipe (2) after foaming and condensing the air, saturated with humidity, in the condensation chamber (3) and drawing off the fresh water.
