“…Fath and Elsherbiny (1993) studied the effect of adding a passive condenser on the performance of basin-type still, and they found that 70% of the yield is increased when a condenser is used. Bhardwaj et al (2016) have showed the effect of adding a plastic channels as passive condenser on an inflatable solar still. They found the production of water achieved from the still at a water temperature of 73 °C to be 0.75 l/h which is much higher than a conventional still.…”

Pure and fresh water is being scarce day by day. Although Bangladesh is a riverine country, pure drinking potable water is not a cheap commodity. Most of the people in the cities boil water to drink, and people of the villages take tube-well's water directly, which might have high amount of heavy metal like arsenic. Solar still is a cheap and very useful renewable technology, which can be used in Bangladesh extensively everywhere at the rooftop as a pure water source. Objective of this paper was to find a low cost portable and easily maintainable passive solar still for southern part of Bangladesh. All the parameters of passive solar still are studied, and it is found that an inclined stepped solar still with passive condenser, internal and external reflectors, black cotton wick, and with optimum design values can be the desired still, which would give maximum yield. Finally, the optimum values of the parameters are used to propose a cheap design.

“…Adding a built-in condenser will give another possible surface area for the accumulated saturated vapour inside the solar still to condense. The evaporated water must be compensated to keep the water level in the tank steady [15][16][17].…”

Water scarcity is one of the most important problems in Middle East and North Africa. Many researchers believe that solar distillation is the best solution to solve water scarcity, especially since these areas are characterized by abundant solar energy most days of the year. One of the main disadvantages of solar distillates is the low rate of production and therefore the research focuses on the factors that many enhance and improve the rates of production of the solar stills. In this paper, the performance of a passive built in condenser incorporated into a solar still is studied theoretically and experimentally using. A theoretical framework is developed to forecast the productivity performance (accumulated and hourly), the temperatures of the various elements of the stills. The theoretical and experimental results were compared together and discussed thoroughly. Both theoretical and experimental results were in good agreement. The behaviors of both agree well with each other and have similar trends.

“…1,2 According to studies, 76.9%, 34.7%, and 9.7 of total CO 2 , methane, NOx emitted into the air are due to the fossil fuels consumed in the energy sector. 3 In 2015, electricity and heat production, as well as transportation accounted for about two-thirds of CO 2 emissions in the world. Based on the estimations, electricity and heat production accounts for 42% and transportation for 24% of this share.…”

“…Based on the estimations, electricity and heat production accounts for 42% and transportation for 24% of this share. 3 Despite major growth in renewables energies, electricity and heat production is still mainly dependent on coal, a high-carbon fuel, with some countries, including Australia, China, India, Poland, and South Africa supplying more than two-thirds of their required electricity and heat from coal. 3 In Iran, energy consumption has increased by about 188% from 1980 to 2000, while carbon emissions have increased by 142% accounting for 1.3% of the world's total carbon emissions.…”

This study deals with a solid oxide fuel cell- gas turbine (SOFC-GT) hybrid system coupled with a multi-effect evaporation desalination plant with steam condensation. The environmental evaluation is also done due to the importance of waste energy recovery especially waste heat in power generation systems. The evaporation desalination plant is studied for using the excess heat to produce freshwater. The thermodynamic relationships governing different components of the system are first provided, including fuel cells, heat exchangers, gas turbine, and desalination plant. Next, given the absence of previous research on the environmental effects of cogeneration systems, despite its necessity, the study system is analyzed from an environmental point of view. Accordingly, the impacts of the system performance parameters, including the fuel consumption coefficients, compressor pressure ratio, fuel pre-reforming percentage, and the steam to carbon ratio are investigated on the CO2, CO, and NOx emission rates. Based on the findings, it is concluded that of different species, the impacts of CO, CO2, and NOx emission rates are significant on the environment. Thus, the impacts of pressure ratio and pre-reforming percentage on their emission rates have been studied. The results revealed with increasing the compressor pressure ratio, increasing the fuel consumption coefficients, and decreasing the fuel cell's exhaust temperature, the CO and NOx emission rates and corresponding social costs diminished. On the other hand, with elevation of the ratio of steam to carbon, the recovery rate, the fuel cell's exhaust temperature, the concerned gas emission rates, and corresponding social costs increased.
