Hemispherical solar still: Recent advances and development

Advanced nanostructured materials in solar interfacial steam generation and desalination against pathogens: combatting microbial-contaminants in water – a critical review

“…Most reviews in both systems focused on the type of material, as the materials are the cornerstone of fabricating a highly efficient structure. In recent years innumerable studies have reviewed solar stills in terms of the type of materials, [13][14][15][16][17][18][19] cooling and heating methods, [20][21][22][23][24] designs and geometries, [25][26][27][28][29][30][31][32] modeling and optimization, [33][34][35] economic and cost analysis, [36][37][38] thermodynamic parameters, [39][40][41][42] integration with different collectors and heat exchanger [43][44][45][46][47][48][49] and effect of climate parameters. 50,51 Moreover, in the last decade, countless studies in solar interfacial evaporators reviewed the use of different types of materials, [52][53][54][55][56][57][58]…”

Development of a Sustainable Solar water Desalinator Using a Novel Hollow Hemispherical Grid Shell Solar Selective Absorber Designed via Phasor Particle Swarm Algorithm

“…This reliance on fossil fuels has had severe implications, including a significant rise in global greenhouse gas emissions and the depletion of finite fossil fuel resources. Additionally, the environmental impact of desalination extends to the discharge of brine into the ocean, resulting in adverse effects on marine life and ecosystems (Younis et al, 2022).…”

“…However, a larger surface area also entails higher heat loss, potentially diminishing the overall effectiveness of the solar still. Therefore, it is essential to tailor the design of the solar still to strike a balance between surface area and heat loss (Younis et al, 2022). The design of the solar still also significantly influences the ease of its construction and maintenance.…”

Use of Electrolysis to Produce H2 from Natural and Modified Water

“…

Hydrogen does not exist too much in the natural state; it is necessary to spend the energy to produce it by dissociating the molecules in which it is contained. [1] Global hydrogen production, estimated at 55 [2] million tons per year, primarily relies on fossil fuels, with natural gas accounting for 49%, oil for 29%, coal for 18%, and only 4% generated through water electrolysis. [3] Currently, majority of hydrogen is produced by breaking down hydrocarbons, predominantly through natural gas reforming, partial oxidation of hydrocarbons, and coal gasification.
