Cooking performance assessment of a phase change material integrated hot box cooker
Previous research on solar box cookers focusing on the bulk usage of energy storage materials is a costly technique for performance enhancement. Bulk energy storage materials take much time to charge and, thus, result in a low rate of cooking at the start. Therefore, a hot box solar cooker has been developed and experimentally studied for thermal performance enhancement in a hilly region of Uttarakhand, India. A bed of phase change material (paraffin wax) filled with small capsule-shaped containers was prepared (detachable) and placed over the cooking tray of the tested cooker. These containers were vertically positioned over the bed to enhance the heat transfer rate inside the cooker to attain a fast-cooking response. Notably, the combined effect of extended geometry with PCM is an excellent method to increase the efficiency of a solar cooker. As per the author’s knowledge, likely techniques have not been studied for a box cooker to achieve a fast-cooking rate in any hilly region up to date. The results of cooking tests show that the cooking plate attained a maximum temperature of about 150 °C. It is because of the combined effect of extended fins (vertical capsules) and PCM filled inside them. The results of the experimental study show that the thermal efficiency of the cooker was found to be about 45.7%, the cooking power was calculated about 54.71 W, the heat transfer coefficient was estimated about 311 W/m
2
°C, and the overall heat loss coefficient was computed about 5.71 W/m
2
°C. This modified cooker costs about $48.19, and the payback period is about 03 years and 11 months. Cooking trials also showed that the present SBC could cook almost all the dishes commonly cooked in Uttarakhand.

Energetic and exergetic performance comparison of three solar cookers for developing countries
Three different domestic solar cookers are compared experimentally during water heating experiments using different loads. The solar cookers experimentally tested using energy and exergy thermal performance parameters are: a solar box cooker without a reflector, a solar box cooker with a reflector and a parabolic dish solar cooker. The rate of heat losses is more detrimental to the performance of the parabolic solar cooker since the cooking vessel is exposed more to the ambient weather conditions. Heat losses seem to have little effect on the performance of the solar box cookers. The solar box cooker with the reflector shows the highest average energy efficiencies, which increase with the water heating load. The parabolic solar cooker shows the lowest average energy efficiencies with the lower loads, which increase to be higher than those of the solar box cooker without the reflector at the higher loads. The solar box cooker with the reflector shows the highest average energy and exergy efficiency values, which are not dependent on the water load. The parabolic dish solar cooker shows average exergy efficiencies, which increase with the water heating load. The greatest cooking potential in terms of the speed of cooking is shown by parabolic dish solar cooker. The best overall thermal performance is shown with the solar box cooker with a reflector, but its cooking speed is rather slow when compared to the parabolic dish solar cooker. The solar box cooker without the reflector shows the worst thermal performance in most of the tested parameters except for the heat losses where it shows the lowest heat loss factors for all the experimental tests.

Solar cooking innovations, their appropriateness, and viability
The successful use of solar energy for cooking requires the systems adopted not only to have technical attributes that conveniently address specific cooking requirements but also are socially and economically acceptable to its end-users. When displacing cooking fuels used in developing countries, solar cooking can lead to (i) improved health in children and women, (ii) less local forest degradation, (iii) less local pollution, and (iv) lower contributions to global greenhouse gas emissions. The diverse range of thermal and photovoltaic solar cooking systems available, or under development, in different regions of the world is discussed in the present work. Particular attention is given to the social, cultural, and economic factors that have limited adoption of solar cookers. Technical developments that address these limitations are shown to only be effective when they facilitate traditional ways of cooking particular foods in and at desired times in specific climates.

One of the key areas of the UN’s sustainable development goals is growing affordable and clean energy. Utilizing solar energy that is now accessible will significantly lessen the demand for fossil fuels. Around the world, cooking is a crucial activity for homes and uses a lot of non-renewable energy. Uncontrolled firewood usage results in deforestation, whereas using biomass-related fuels in inefficient stoves can result in smoke emanating from the kitchen and associated health issues. The benefits of solar cooking include reducing smoke-related problems and saving on fossil fuels and firewood. Applying thermal storage systems in cooking helps households have all-day cooking. This review article presents the research and development of a solar cooking system that transfers solar energy into the kitchen and integrates with the thermal energy storage system, finding the factors affecting indoor solar cooking performance. Adding portable cooking utensils helps in improved solar indoor cooking. Multiple phase change materials arranged in cascaded to store thermal energy helps in quick heat transfer rate, thus enabling better and faster cooking. A novel indoor solar cooker with an innovative arrangement of evacuated tube-based compound concentrating parabolic (CPC) collectors with a cascaded latent heat thermal energy storage system is proposed and needs to be tested under actual meteorological conditions.

Exploring the role of phase change materials in low-temperature solar thermal applications: an extensive overview with challenges and opportunities
Solar energy is widely acknowledged as a renewable and environmentally friendly energy source. Efficient storage of heat energy is a crucial challenge in solar thermal applications. Phase change materials (PCMs) have gained prominence due to their unique ability to store and release thermal energy through phase transition. The advantageous characteristic of PCMs is their low melting point, facilitating efficient heat storage and retrieval through latent heat of vaporization. This comprehensive review focuses on selecting suitable PCMs for diverse applications, considering their melting point and thermal properties. PCMs with high heat capacity and excellent solar radiation absorption are favored in solar applications, especially for systems requiring large thermal energy storage capacities. This review article underscores the importance of PCMs in low-temperature (0–120 °C) solar thermal applications such as solar desalination, solar water heaters, solar cookers, solar dryers, solar air heaters, and solar chimneys, emphasizing their role in practical heat storage and release. By carefully selecting PCMs based on melting point and thermal properties, the performance and efficiency of solar thermal systems can be optimized, contributing to a greener and more sustainable future.

Performance Analysis of Box-type Solar Cooker with New Selective Coatings
This paper offers a thorough experimental investigation of how applying selective coatings can enhance the performance of solar cookers in the box type. The application of black chrome on galvanized steel and black nickel on nickel-plated steel is given special attention. The results of the study show that the Black Nickel coating retains heat better than the Black Chrome coating because of its lower emissivity. When there is a large load, effective heat transfer from the absorber plate to the pot is quite important. Graphical examination of the temperature profiles indicates that when there is no load, the Black Nickel coating resulted in absorber plate temperatures ranging from 162-168°C, whereas the Black Chrome coating reached temperatures of 155-159°C. Under a load, the temperature of the absorber plate coated with Black Nickel ranged from 150-153°C, whereas the Black Chrome coating resulted in temperatures of 144-147°C. The findings align with the cooking pot temperatures, showing that the Black Nickel coating consistently outperformed the Black Chrome coating by obtaining higher temperatures in both loaded and unloaded circumstances. The ability of these coatings to swiftly attain greater temperatures is demonstrated by this research, which enhances the solar cooker’s efficiency both with and without a load. The findings represent a significant improvement in solar cooker technology since they offer a cost-effective and sustainable substitute for locations with sufficient sunshine.

Microstructural and leaching behavior of aluminum pressure cookware: A case for standardized testing in Saudi Arabia
This study evaluates the chemical composition, leaching behavior, and microstructural changes of aluminum pressure cookers through Optical Emission Spectroscopy (OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), and Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS). OES analysis revealed that the cookware comprises 97.8–98.6% aluminum, with manganese and iron as prominent alloying elements, alongside trace amounts of potentially toxic elements such as lead, cadmium, and arsenic. Leaching tests demonstrated minimal elemental migration in boiling water but significantly elevated leaching in 4% acetic acid, with manganese reaching 26.83 ppm, iron 85.849 ppm, and lead 0.0398 ppm. SEM-EDS analysis revealed severe surface degradation and pitting in samples exposed to acidic conditions, coupled with localized increases in toxic elements. These findings highlight the heterogeneous nature of leaching, driven by microstructural inconsistencies and environmental factors. The study underscores the necessity of rigorous testing protocols, particularly using SEM-EDS investigations, to identify and mitigate risks associated with metal migration from aluminum cookware. Establishing regulatory standards and educating consumers on the safe use of aluminum cookware, especially in acidic food preparations, is critical to safeguarding public health in Saudi Arabia.
