To address the worldwide issue of water scarcity, prompt action is required. Solar desalination is one potential sustainable solution that could be considered for this problem. A nano-structure solar still that does not require touch is the subject of this investigation. As a result of the non-contact structure, the solar still structure does not meet water, which not only extends its lifespan but also prevents salt from accumulating when it is doing continuous operation. One side of the non-contact structure is made to be a high absorber of sun’s light, while the other side is made to be a high emitter of the infrared wavelength. A total of three and four centimeters of saline water were used in the experiments that were conducted. The information was gathered over the course of three months to evaluate the performance of the construction in a variety of specific environmental conditions. Several characteristics, such as glass, basin, vapor, water, absorber, ambient temperature, time, and solar intensity, were measured over the course of the experiment. In proportion to the increasing water depth, the NCNS system generates a greater quantity of distillate than the CSS system. When compared to the CSS approach, it generates 15% and 8% more distillate for depths of 3 cm and 4 cm, respectively. Hence, non-contact structure is sustainable solution for solar desalination.
