This thesis presents the Lotus 37-I, a new unique design for a passive solar cooker with an emphasis on sustainability and cooking efficiency, and gives an overview of the technical, social, environmental, and economic implications of solar cooking. I, Alex Haney worked with Jason Wallace to complete this project in three phases: background research, design and build, and sustainability analysis. During the background research phase we researched the current state of the art of solar cooking, looked at the leading designs on the market, and gained a thorough understanding of the social, economic, technical, and scientific contexts of solar cooking. We tested the performance of the Tulsi®-Hybrid Solar Oven model over the summer of 2011. During the design and build phase, we brainstormed and formulated our own unique design based on our working knowledge of the subject and chose a design using an engineering decision matrix to weigh different options. During the final phase we analyzed the cost of our cooker design and investigated the practicality of presenting our design to the market and investigated the feasibility of attaining a patent. We found that the performance of our design, the Lotus 37-I, is comparable to other designs on the market, and, with its emphasis on using recycled material, it can provide a sustainable cooking option for the developing world. However, we did not seek a patent at this time due to the large financial investment required and the need for further design improvement.
This study investigates the determining factors for the successful adoption of institutional solar cookers. Qualitative interviews were conducted with 24 institutions in four different countries that had a particular type of solar cooker installed. A Qualitative Comparative Analysis (QCA) approach was employed to answer the question at hand. The analysis results in four core variables, the presence of which implies the successful adoption of solar cookers. These are: (1) 'High Compatibility with Schedule of Daily Routine', (2) 'High Compatibility with Local Food Characteristics', (3) 'High Levels of Economic Motivation' and (4) 'High Levels of Environmental Motivation'. An interesting result is that institutions that have successfully adopted solar cookers are religious institutions and that these institutions show a very strong affinity for protecting nature as part of their spiritual belief. Furthermore, the condition 'High Compatibility with Local Food Characteristics' took on another spiritual meaning apart from the actual objective taste; it became associated with purity, one major principle of Hinduism.
This definitive textbook deals with all aspects of solar box cookers. While it is a suitable reference for the experienced builder, it is widely used for technology transfer in Third World locations & is comprehensible by young students, housewives & those without a technical education. The emphasis is on inexpensive, locally available materials & handcraft methods. It covers principles & guidelines for designing your own solar box oven in the materials of your choice. Designing, building & using solar box devices for a variety of non-cooking purposes are discussed. Four different sets of plans for simple cardboard solar box cookers are included along with recipes & cooking strategies. It is an indispensable guide for those interested in serious solar cooking.

A boy, a science project and an answer to a critical problem. During monsoon season in Bangladesh, Iqbal’s mother must cook the family’s meals indoors, over an open fire, even though the smoke makes her and the family sick. So when Iqbal hears that his school’s science fair has the theme of sustainability, he comes up with the perfect idea for his entry: he’ll design a stove that doesn’t produce smoke! Has Iqbal found a way to win first prize in the science fair while providing cleaner air and better health for his family at the same time? Sometimes it takes a kid to imagine a better idea — make that an ingenious one!
Shows how to harness the sun's energy in preparing food with plans for building solar ovens. Includes over 90 recipes.
This volume originated as a report given to the World Bank in 1978 on the household energy consumption of both the urban and rural poor in developing countries. Originally published in 1979, this title supplies alternatives for meeting the domestic energy needs of the poor in developing countries and looks at the results of experiments in introducing new forms of energy. This book is a valuable resource for public policy makers and students interested in environmental studies and developmental studies.
