Abstract: The invention pertains to a device for the condensation of water from an aqueous liquid by using a temperature gradient, which device includes: (a) a vapor chamber that can be brought in contact with a condensation compartment wherein at least part of the water vapor from the aqueous liquid condenses, and wherein inside of said vapor chamber is located (b) an evaporation compartment having a least a wall with an outer surface and which includes a closed, hollow and water permeable membrane wherein the vapor chamber has an outer surface that includes a substantially water-impermeable insulation skirt with an inner and an outer surface, such that there is a gap between the inner surface of the insulation skirt and the outer surface of the evaporation compartment, and wherein the vapor chamber has a lower surface of an active width (w) which is at least 10% of the effective diameter (d) of the evaporation compartment.

Abstract: The invention pertains to a device (1) for the condensation of water from an aqueous liquid by means of a temperature gradient, which device comprises, (a) a vapor chamber (5) that can be brought in contact with a condensation compartment (4) wherein at least part of the water vapor from the aqueous liquid condenses, and wherein inside of said vapor chamber is located, (b) an evaporation compartment (2) having a least a wall with an outer surface and comprising a closed, hollow and water permeable membrane, and which vapor chamber has an outer surface that comprises a substantially water-impermeable insulation skirt (3) with an inner and an outer surface, such that there is a gap between the inner surface of the insulation skirt and the outer surface of the evaporation compartment, and wherein the vapor chamber has a lower surface of an active width (w) which is at least 10% of the effective diameter (d) of the evaporation compartment.
