“…The time of achieving maximum efficiency for WBM was 3:00 pm and without WBM was 2:00 pm. The curve obtained for the instantaneous efficiency was found in line with the research work done by Bilal et al 32 …”

“…The current findings show that the solar still yields a rise for a reduction in the storage mass of WBM. This is due to the very low‐temperature conductivity of the WBM relative to previous materials, as stated by Bilal et al 32 and they tested lower thermal conductivity material pumice stones in SBSS with 5 and 10 kg mass. Deshmukh and Thombre 33 had carried out the work on the different sensible heat storage materials on the performance of solar still.…”

In this current study, a single basin solar still (SBSS) was explored in the climatic state of Patan (23.84° N, 72.12° E) India over March 2019. The SBSS was examined with the use of waste brick magnesia (WBM) for the same amount of water (10 L). For experimentation, three same‐sized SBSS were taken with 3 and 6 kg WBM and without storage materials. It was found that a daytime yield for SBSS of 2.27 L without storage materials was obtained; and this was reduced for SBSS with 3 and 6 kg WBM to 1.96 and 1.75 L, respectively. It has also been noticed that the yield of SBSS during off‐sunshine hours due to the energy storage capacity increased with WBM but the combined (daytime + off‐sunshine hours) yield was found reduced with an increment in a mass of the WBM. It was found that the maximum instantaneous thermal efficiency of the SBSS without WBM, 3 and 6 kg WBM was 60.24%, 45.65%, and 54.26%, respectively. Overall thermal efficiency was also determined and obtained to be higher for SBSS without WBM as storage.

“…The application of thermal energy storage materials inside the stills increases the daily operation period that helps in producing more water. Bilal et al [9] had used the two different masses (5 and 10 kg) of pumice stones in a still basins to store thermal energy as heat storage material. In the case of 10 kg, the productivity was less than as in the case of 5 kg by 130ml for the same water depth in both cases.…”

The solar stills were developed to fulfil the freshwater need of the growing population. The paper presents the recent modifications made in still to improve their productivity like the application of phase change materials (PCM), connecting flat-plate collector (FPC), use of nanoparticles, stepped solar still, and attaching separate condenser in the still. Active solar stills are found more productive than passive ones and the thermal efficiency of active solar stills lie in the range of 50-70%, which is far better than passive still having 20-55% thermal efficiency. According to the literature studied in the paper, the maximum productivity of active solar still is 10 litres per day and in passive solar stills, it is 6 litres per day. The different approaches used to carry out the heat and mass transfer analysis of single and double slope active and passive solar stills are also discussed in the paper.

“…The desalination process using nonrenewable energy sources causes greenhouse gas emanation, which causes ecological contamination but leads to a sustainable power source as a substitute for powering the units. [1][2][3][4][5] The performance of the conventional solar still (CSS) was improved by using pumice stones, 6 gravel, 7 absorbent materials, 8 black color sponge, 9 integration with another solar still, 10 and using nanoparticles/fluids. [11][12][13][14][15][16][17][18][19][20] A novel portable thermoelectric desalination system has been researched by Hayden et al 21 In their work, thermoelectric material (TEM) was used to augment the condensation and evaporation rate.…”

In this paper, an experimental study of the conventional solar still (CSS), the conventional solar still with glass cooling (CSSGC), the conventional solar still with basin heating (CSSBH), and the conventional solar still with glass cooling and basin heating (CSSGCBH) was carried out on the basis of the distilled water production, the energy efficiency (EnE), the exergy efficiency (ExE), and economic analysis. The CSSGC and CSSBH contain Peltier modules for cooling the glass and heating the basin. The evaporative heat transfer coefficient for all the experimental stills was calculated. The values of daily distilled water production from the CSSGCBH, CSSBH, CSSGC, and CSS were 4.56, 3.79, 2.49, and 1.89 kg/m 2 , respectively. The daily distilled yield of the CSSBH and CSSGCBH were increased by 58.55% and 50.13%, respectively, as compared with the CSS. Moreover, the daily EnE and ExE of the CSSGCBH were 27.03% and 3.5%, respectively, whereas the EnE and ExE of the CSS were 10.88% and 1.3%, respectively. Furthermore, the cost of distilled water Abbreviations: CSS, conventional solar still; CSSBH, conventional solar still with basin heating; CSSGC, conventional solar still with glass cooling; CSSGCBH, conventional solar still with glass cooling and basin heating; EHTC, evaporative heat transfer coefficient; EnE, energy efficiency; ExE, exergy efficiency; T w − T g , temperature difference between the water and glass cover.
