One method of water purification that creates drinkable water is the solar still (SS). Numerous studies have looked into the design of various SSs and the use of various materials to boost these SS’s production. The most well-known SS kinds were covered in this study, along with the various materials and adjustments that were thought to increase these systems' productivity.

Thus, this study compares the expense of water produced per liter and the different designs of SS, providing a tool that facilitates the selection of the optimal SS in terms of operating capacities and expected productivity.

Here, a tandem passive cooler, combining radiative cooling and latent thermal energy storage, is presented to achieve the dual functionalities of passive cooling and thermal shock resistance. Specifically, the radiative cooling performance of this cooler is enabled by its high solar reflectivity (0.928) and high infrared emissivity (0.947), while its efficient isothermal heat release and absorption ensure temperature stability and high thermal energy storage. Consequently, by overcoming the limitations of both radiative cooling and latent heat thermal energy storage, this tandem passive cooler achieves a maximum temperature reduction of 5.37 °C and an average passive cooling temperature of 3.01 °C, enabling effective radiative cooling. Furthermore, this cooler reduces the maximum temperature of a heated silicon wafer by 27.56 °C compared to radiative cooling alone under thermal shock situations, demonstrating superior thermal shock resistance. Upon cessation of the thermal shock, the solidified latent thermal energy storage materials release their stored energy, mitigating excess heat and preventing overcooling of electronic devices, thereby ensuring the stable operation of electronic systems.
