Summary: Solar desalination is a promising technology to meet the increasing demand for fresh water. A study compared the performance of a conventional solar still and a modified solar still with an inbuilt condenser and agitator. The modified still showed 98.69% higher productivity and 24.42% higher energy efficiency compared to the conventional still. These improvements were achieved by the agitation effect of the agitator and the increased condensing area in the modified still.

Summary: This study aims to develop a single solar still that is directly connected with a solar parabolic trough and does not utilize any heat exchanger. Through field experiments, it was found that the overall water productivity of the modified solar still increased by 177% compared to the conventional still. The study also proposed future investigation of a step-shaped conical unit for the same device, which appears more promising and easier to handle, install, and maintain.

Summary: Solar stills are convenient tools for desalinating water using solar energy but are not very efficient. However, the use of thermoelectric materials can improve their performance. Thermoelectric materials can be used as coolers or heaters in the solar still system, as well as generators of electricity. The study discusses and compares the modifications made to solar stills using thermoelectric materials to produce potable water from saline or brackish water, concluding that they enhance performance and increase the yield.

Summary: This study experimentally investigates the performance of a solar still with induced turbulence (SWIT) that uses a novel approach to improve productivity. A metal wire net immersed in the water basin of the still is subjected to small intensity vibrations generated by a direct current vibration micro motor, inducing turbulence in the water and enhancing evaporation. A comprehensive analysis of the energy, exergy, economics, and environment of SWIT is conducted and compared with a conventional solar still (CS) of the same size. The results reveal that SWIT has a significantly higher heat transfer coefficient, yield, thermal efficiency, and exergy efficiency compared to CS. The cost of water from SWIT is 0.028 $ with a payback period of 0.74 years, and it also generates carbon credits of 105 $.
