“…Despite these innovations, solar distillates are not yet commercially viable due to their limited production capacity. To address this, researchers have investigated the use of phase change materials (PCMs) with high latent heat capacity to absorb and store energy [42][43][44][45]. Additionally, some studies have examined graded solar stills and simple solar distillers equipped with a single basin and PCM for energy storage.…”

“…Maintaining a substantial temperature difference between the water and the cooler glass cover has also been found to be beneficial [46]. Other Researchers has shown that magnetic fields have a substantial impact on water evaporation rates [47][48][49][50][51]. Consequently, the application of magnetic fields stands out as one of the most influential and contemporary techniques for enhancing the productivity of solar stills [52].…”

In the face of an escalating global water crisis, countries worldwide grapple with the crippling effects of scarcity, jeopardizing economic progress and hindering societal advancement. Solar energy emerges as a beacon of hope, offering a sustainable and environmentally friendly solution to desalination. Solar distillation technology, harnessing the power of the sun, transforms seawater into freshwater, expanding the availability of this precious resource. Optimizing solar still performance under specific climatic conditions and evaluating different configurations is crucial for practical implementation and widespread adoption of solar energy. In this study, we conducted theoretical investigations on three distinct solar still configurations to evaluate their performance under Baghdad's climatic conditions. The solar stills analyzed include the passive solar still, the modified solar still coupled with a magnetic field, and the modified solar still coupled with both magnetic and electrical fields. The results proved that the evaporation heat transfer coefficient peaked at 14:00, reaching 25.05 W/m 2 .°C for the convention pyramid solar still (CPSS), 32.33 W/m 2 .°C for the magnetic pyramid solar still (MPSS), and 40.98 W/m 2 .°C for elecro-magnetic pyramid solar still (EMPSS), highlighting their efficiency in converting solar energy to vapor. However, exergy efficiency remained notably lower, at 1.6%, 5.31%, and 7.93% for the three still types, even as energy efficiency reached its maximum of 18.6% at 14:00 with a corresponding peak evaporative heat of 162.4 W/m 2 .

“…16 It is found that the demand for pure water by a simple family was satisfied by 3% and the system is efficient when integrated with a heater. Alawee et al 17 have used dangled cord wicks in pyramid solar still and studied the mechanism of wick during distillation. It has been revealed that the still with cords of wick produced higher distillate yield and 53% daily efficiency higher than that of conventional solar still.…”

“…Consequently, scientists have introduced various solutions to overcome this limitation of low productivity [12]. Innovations to the layout and functioning of solar desalination processes were among the answers [13][14][15][16]. As a result, the experts converted distillers, which are within the desalination schemes, to stepped (distiller with vertical steps to increase surface area) [17][18][19], disc (distiller with rotating discs to increase the surface area and break surface tension) [20], vertical solar distillers [21], tube-shaped (tubular distiller to enhance evaporation and condensation) [22][23][24], drum (distiller with rotating cylinders inside it) [25][26][27], photovoltaic thermal [28,29], fins (distiller with longitudinal fins) [30,31], trays (distiller with suspended trays) [32][33][34], tilted [35], woven materials [36][37][38], zig-zag (distiller with corrugated surfaces to improve evaporation) [39][40][41], spheric [42,43], doublestage [44][45][46], multi-stage [47], inverted absorber [48], convex [49,50], and pyramid [51][52]…”

As is widely known, the issue of freshwater scarcity affects practically all people, and all are looking for innovative and workable ways to attempt to solve this issue. In this work, a novel method of desalination is proposed. The proposed system consists of a solar collector (PTSC), evacuated pipe (EP), condenser (CU), and separation unit (SU). The working principle of the system is heating the feed saline water using the PTSC and EP and controlling the water flow rate to control the output conditions of the EP. The produced vapor is therefore separated from salty water using the SU. In addition, the generated steam is condensed into the CU to produce a freshwater distillate. Consequently, the effect of solar radiation on the affecting temperatures was tested. In addition, the effect of using different water flow rates (6, 7.5, 10, 20, 40, and 60 L/h) inside the EP on the system productivity was investigated. The primary findings of this work may be highlighted in relation to the experiments conducted. At midday, when ultraviolet irradiance reached its highest, the EP’s water flow entrance and outflow had the largest temperature differential. In addition, the lower the water flow rate inside the EP, the higher the water temperature, the higher the evaporation rate of the system, and the greater the freshwater productivity of the system. At 6 L/h, the water’s highest temperature was 92 °C. Moreover, the best performance of the system was obtained at 7.5 L/h, where the freshwater production and average daily effectiveness of the distillate process were 44.7 L/daytime and 59.6%, respectively. As well, the productivity of EP was augmented by around 11.86% when using graphite nanoparticles. Additionally, the distilled freshwater from the system operating at the flow rate of 7.5 L/h costs 0.0085 $/L.
