Inadequate water supply is a crucial issue that involves millions of people living in the poorest areas of the World. The technologies associated to water harvesting from the atmosphere are receiving more and more attention due to the possibility of extracting water from air directly where it is needed, with no extra transportation nor substantial energy supply required. This work aims to contribute to the realization of an Atmospheric Water Harvesting Prototype based on adsorption material technologies and coupled with a low temperature heat source. The system is integrated with flat plate solar thermal collectors, installed directly on the prototype. The peculiarity of this system is its versatility, being all contained in a square meter basis, and the possibility of realizing a complete passive system.
