In India, due to the high price of cooking gases, people still cook with noncommercial fuels like kerosene and firewood. These cause a lot of health problems and also harm the environment. A clean solution to this problem is to use a solar cooker. A solar cooker suffers from the problem of low utility and hence takes a longer period of time for cooking. To counter this problem and reduce cooking time, the solar cooker is tested with charcoal coated utensil. In this paper, a parabolic-type domestic solar cooker is tested for the same utensil with and without cost effective thermal coating. It is observed that the effectiveness and efficiency of cooking is considerably increased by using the charcoal coating on the utensil. Considering the economic condition of the people of the selected area, this method provides a cost effective way to increase the cooking effectiveness of the solar cooker and reduce dependency on noncommercial fuels.
在印度，由于烹饪燃气价格高昂，人们仍使用煤油和木柴等非商业燃料做饭。这些燃料会引发诸多健康问题，还会对环境造成危害。解决这一问题的清洁方案是使用太阳能炊具。太阳能炊具存在实用性低的问题，因此做饭耗时较长。为解决这一问题并缩短烹饪时间，对涂有木炭的器具在太阳能炊具上进行了测试。本文针对同一器具，对有无经济高效热涂层的抛物面型家用太阳能炊具进行了测试。结果发现，在器具上使用木炭涂层可显著提高烹饪的有效性和效率。考虑到所选地区人们的经济状况，该方法提供了一种经济有效的方式来提高太阳能炊具的烹饪效果，并减少对非商业燃料的依赖。
