A container for purification of water by a combination of filtering, heating, and UV-radiation of the water is disclosed. The container includes a first section, which at least partly includes a sunlight permeable layer, and a second section, which at least partly is opposite the first section and at least partly includes a sunlight absorbing and infrared radiation emitting (IR-emitting) layer. The first and the second section together enclose a volume, in which the water can be received to be heated by and exposed to sunlight. According to the present invention, the first section is arranged such that the permeable layer is essentially flat, and the second section is arranged such that the volume includes at least a first and a second portion, wherein the first and the second portion, respectively, have a first and a second distance, respectively, between the permeable layer and the sunlight absorbing and IR-emitting layer, where the first and second distances are mutually different. A temperature difference between the water in the first and second portion is created after a period of sun exposure.

1. Container (100) for purification of water by utilizing sunlight, including a first section (110, 210), which at least partly includes a sunlight permeable layer (111, 211), and a second section (120, 220), which at least partly is opposite the first section and at least partly includes a sunlight
1. Container (100) for purification of water by utilizing sunlight, including a first section (110, 210), which at least partly includes a sunlight permeable layer (111, 211), and a second section (120, 220), which at least partly is opposite the first section and at least partly includes a sunlight absorbing and infrared radiation emitting (IR-emitting) layer (121, 221), wherein the first and the second section together enclose a volume (130, 230), in which the water can be received to be heated by and exposed to sunlight, characterized in that the first section (110, 210), is formed such that the permeable layer is essentially flat, andthe second section is arranged such that the volume includes at least a first and a second portion, wherein the first and the second portion, respectively, have a first and a second distance, respectively, between the permeable layer (111, 211) and the sunlight absorbing and IR-emitting layer (121, 221), wherethe first and second distances are mutually different, wherein a temperature difference between the water in the first and second portion is created after a period of sun exposure. 2. Container (100) as claimed in claim 1, characterized in that the second section includes a surface being arranged such that the sunlight absorbing and IR-emitting layer (121, 221) on the surface includes at least two surface portions (222, 223, 373, 374), wherein the at least two surface portions (222, 223, 373, 374) are on mutually different height levels in relation to a propagation plane for the surface, and thereby determine the first and second distances. 3. Container (100) as claimed in claim 2, characterized in that the at least two surface portions (222, 223, 373, 374) of the sunlight absorbing and IR-emitting layer (121, 221) are made up of any of the shapes in the group of: an essentially centered plateau surrounded by a valley; a plateau and a valley arranged alongside each other in the cross-direction of the container; a plateau and a valley arranged alongside each other in the lengthwise direction of the container. 4. Container (100) as claimed in claim 2, characterized in that the at least two surface portions (222, 223, 373, 374) of the sunlight absorbing and IR-emitting layer (121, 221) are made up of any of the shapes in the group of: at least one ridge and a valley, arranged in the lengthwise direction of the container; at least one essentially spherically shaped hill surrounded by a valley. 5. Container (100) as claimed claim 2, characterized in that the at least two surface portions (222, 223, 373, 374) of the sunlight absorbing and IR-emitting layer (121, 221) are arranged as having essentially rectilinear borders between the two surface portions. 6. Container (100) as claimed in 2, characterized in that the at least two surface portions (222, 223, 373, 374) of the sunlight absorbing and IR-emitting layer (121, 221) are arranged as having essentially wave formed borders between the at least two surface portions (222, 223, 373, 374). 7. Container (100) as claimed in claim 1, characterized in that the second section (120, 220) includes one bottom and four walls, wherein the surface is made up of the bottom. 8. Container (100) as claimed in claim 1, characterized in that the sunlight absorbing and IR-emitting layer (121, 221) is arranged such that the sunlight absorbing ability is decreased for at least one part of the sunlight absorbing and IR-emitting layer (121, 221). 9. Container (100) as claimed in claim 8, characterized in that the sunlight absorbing ability is decreased by applying an essentially white color to the at least one part. 10. Container (100) as claimed in claim 8, characterized in that the at least one part is situated in a surface portion (222, 374) of the sunlight absorbing and IR-emitting layer (121, 221), which is adjacent to the portion of the volume having a longer distance between the permeable layer (111, 211) and the sunlight absorbing and IR-emitting layer (121, 221). 11. Container (100) as claimed claim 1, characterized in that a shading of at least one part of the sunlight absorbing and IR-emitting layer (121, 221) is arranged by providing the permeable layer (111, 211) with at least one portion of a sunlight non-permeable material. 12. Container (100) as claimed in claim 11, characterized in that the at least one shaded part is situated on a surface portion of the sunlight absorbing and IR-emitting layer (121, 221), which is adjacent to the portion of the volume having a longer distance between the permeable layer (111, 211) and the sunlight absorbing and IR-emitting layer (121, 221).
