Experimental assessment of a cooling device with no moving parts exploiting a salinity difference Since the beginning of the previous century the most dominant technology that provided cooling for diverse needs is the mechanical vapor compression cycle. Still nowadays the greatest fraction of room cooling and refrigeration as well as a significant portion of room heating is achieved by means of the same technology developed in the early 1930s. Despite its robustness, reliability and scalability, a solution that comprises operating fluids that do not have a detrimental impact to the environment when released has not been found yet[1]. At the same time the term sustainability has become even more relevant the last decade leading into an increased demand for less energy consumption and for the use of environmentally friendly methods and materials.
