1. A device for extraction of water from gas comprising a container with at least one sealable opening, at least one lid, at least one hygroscopic material and an energy delivery device, wherein the container is made of a heat conducting non-transparent material and wherein the energy delivery device is arranged in the hygroscopic material, wherein the hygroscopic material is arranged in a frame, and wherein the hygroscopic material is separated from walls of the container and surrounded by the gas, allowing water in the hygroscopic material to be vaporized to the surrounding gas when heated by the energy delivery device. 2. The device according to claim 1 wherein the energy is in the form of heat. 3. The device according to claim 1 wherein the energy delivery device is a heating device. 4. The device according to claim 1 wherein the device further comprises a pump arranged in order to reduce the pressure in the container when sealed. 5. The device according to claim 1 wherein the walls of the container are partly made of or coated with a hydrophobic material. 6. The device according to claim 1 wherein the hygroscopic material comprises molecular sieves, active carbon, zeolite, silica gel, LiCl, CaCl, NaNO3, wood, sulphates or any suitable material having the capacity of absorbing water/moisture. 7. The device according to claim 1 wherein a fan or a pump facilitates a gas flow into the container. 8. The device according to claim 1 wherein the energy delivery device comprises a microwave generator or resistive heating device or a solar absorber unit. 9. The device according to claim 1 wherein the device also comprises a control mechanism for the opening and the sealing of the lid. 10. The device according to claim 1 wherein the device comprises a draining element. 11. The device according to claim 9 wherein the control mechanism is connected to the hygroscopic material and/or to the energy delivery device. 12. The device according to claim 1 wherein the walls of the container contains grooves, trenches, channels or the like. 13. The device according to claim 1, wherein the container further comprises a window. 14. The device of claim 1, wherein the energy delivery device has a Y or fork shape end part that is arranged in the hygroscopic material, and the end part of the energy delivery device heats the hygroscopic material. 15. The device of claim 1, wherein the energy delivery device has a flat rectangular surface shape end part that is arranged in the hygroscopic material, and the end part of the energy delivery device heats the hygroscopic material. 16. The device of claim 15, wherein the energy delivery device has an end part that comprises a plurality of wires, and metal conducting particles are arranged in the hygroscopic material, and the end part of the energy delivery device heats the hygroscopic material. 17. A method for extracting water from gas using a container comprising at least one opening, at least one hygroscopic material, at least one energy delivery device and at least one lid comprising: arranging the hygroscopic material in a frame, wherein the hygroscopic material is separated from walls of the container and surrounded by the gas, allowing water in the hygroscopic material to be vaporized to the surrounding gas when heated by an energy delivery device;providing the gas containing water to the container;absorbing water onto or into the hygroscopic material;sealing the container with the lid;heating the hygroscopic material with the energy delivery device arranged in the hygroscopic material until the gas in the container is saturated with water in gas phase;continuing to heat until the remaining absorbed water in the hygroscopic material liquefies without vaporizing first,wherein the walls of the container and the lid of the container are made of a heat conducting non-transparent material. 18. A device for extraction of water from gas comprising: a container made of a heat conducting non-transparent material and having check valve that is opened by a gas flow and closes when the gas flow stops, the check valve configured for connection, within an interior of a building, to an air conditioning or dehumidification arrangement for both daylight and night-time use of the device;a hygroscopic material located within the container; andan energy delivery device that heats the hygroscopic material, an end part of the energy delivery device is arranged in the hygroscopic material, the energy delivery device comprising a resistive metal wire that is arranged in the hygroscopic material and heats the hygroscopic material,wherein the hygroscopic material is arranged in a frame, and wherein the hygroscopic material is separated from walls of the container and surrounded by the gas, allowing water in the hygroscopic material to be vaporized to the surrounding gas when heated by the energy delivery device. 19. The device of claim 18, wherein the end part has a Y or fork shape. 20. The device of claim 18, wherein the end part has a flat rectangular surface shape. 21. The device of claim 18, wherein the end part comprises a plurality of wires and metal conducting particles are arranged with the hygroscopic material.
