Abstract:A solar box cooker (SBC) has been developed for the thermal performance evaluation by operating it on a low cost thermal storage. For this, a mixture of sand and granular carbon has been prepared and tested for an optimum ratio under a solar collector. After testing, the ratio of 4:6 (sand: carbon) has been observed to maintain a high temperature range with long term heat storage. This mixture has been used as thermal heat storage inside the SBC. The experimentation procedure has been conducted under climatic conditions of Moradabad, India. Results indicated that the first Figure of . The system was found feasible for cooking during the off sunshine conditions.

“…Most CSCs have thermal efficiencies varying from 20 to 50% due to varying design of the cookers and concentrators [55]. However, a lot of improvements have been made and are in progress on the thermal efficiency of CSCs [56][57][58]. Higher thermal efficiencies (50-60%) are already reported with parabolic solar cookers (PSCs) [59].…”

“…With a prototype developed to cook Injera [67], it is possible to cook Injera sufficient for all people living in the village considered for this study. CSCs are technologically mature, easily adaptable, convenient to use at any time, and cheap technology with high ecological benefits [52,57,70]. This implies the potential competitiveness of CSC with that of biogas stoves to meet the cooking energy demand of the village at any time of the day taking into account design modifications.…”

Background: Most households in rural developing countries do not have access to modern energy supply. Household level biogas energy was considered as an option but failed due to lack of sufficient resources for its installation and operation. A community energy system can be an option, but most studies focused on off-grid electricity. This energy system cannot be a realistic option particularly for cooking demand. An efficient and suitable system matching local resources and demand expectation needs to be developed which this study focuses on assessing. Biogas and solar energy technologies are viable to establish such kind of a system since they can be converted to different forms of energy. Therefore, this study aims to determine efficient biogas and solar energy production and utilization options for small scale village energy application in rural Ethiopia. Methods: The efficiencies of the production and utilization options are determined based on the system configurations involving resource, conversion, and utilization combination models. We used local resources, data, and relevant literature information for the system analysis. Results: The analysis shows that most energy is needed in the form of heat for cooking and a smaller part in the form of electricity (about 10%). The community waste stream converted to biogas will be enough for cooking, but not enough biogas is left to produce enough electricity. Co-digesting altogether provides biogas that can meet only about 75% of the electricity demand. Concentrated solar cookers can be an alternative for cooking in areas where installation of biogas is not possible. About 2-m 2 size solar concentrator is sufficient to meet each household's cooking energy demand. The lighting and appliance energy demand can be met with photovoltaic (PV) energy produced with reasonably sized panels. However, the use of electrical energy for cooking produced with PV cannot be an economic option with the available technologies. Conclusions: The community energy system involving anaerobic co-digestion (biogas) and/or solar energy technologies is viable to meet the demand when efficient production and conversion is made based on specific local resource supply and demand.

“…Generally, to achieve high-temperature ranges, concentrating type of collectors is used. The parabolic dish-type concentrators have high collector efficiency so it is widely used in the area of solar cooking (Foong et al 2011;Choudhary et al 2013;Lecuona et al 2013;Farooqui 2013;Umanand and Prasanna 2011;Velraj et al 2012;Mussard and Nydal 2013). Foong et al (2011) studied a small-scale double-reflector solar concentrating system with high-temperature heat storage medium (NaNO 3 and KNO 3 ), and a finite element model was used to numerically analyze the latent heat storage unit.…”

“…It was observed that solar cooker with phase change material having outer surface painted black along with glazing stores 32.3 % more heat as compared to PCM in ordinary solar cooker. Lecuona et al (2013) simulated a portable solar cooker of parabolic type using 1-D finite difference method. A numerical model was used to study its transient behavior with two different types of PCMs: paraffin and erythritol.…”

A comparison of thermal performance of solar cooker with two different heat transfer fluid (HTF) and effect of gate valve on discharge process of phase change material (PCM) had been investigated experimentally. In this experimental setup, solar cooker with inbuilt thermal storage unit was connected to evacuated tube collector through connecting pipes. The available solar heat in the collector was transferred to the solar cooker by natural circulation (thermosiphon) of HTF. The water and thermal oil (engine oil) were used separately as HTF to compare the thermal performance of solar cooker. Commercial grade acetanilide was used as thermal storage material in the solar cooker. The PCM discharging process was studied, firstly when both gate valves were open and secondly when both gate valves were closed during discharging process. Then, cooking was carried out using thermal oil as HTF, and both gate valves were closed during discharging of PCM. It was found that with water as HTF, the temperature of PCM at 18:00 h was 10.7°C higher when both valves were closed as compared to the case when both valves were opened, whereas it was 13.1°C in case of thermal oil as HTF. Using thermal oil as HTF, quantity of average energy stored by PCM was increased by an amount of 18.88 % as compared to water as HTF.
