A Review of Cooking Technology Around the World and the Potential of Solar Cooking FACULTY OF ENGINEERING AND SUSTAINABLE DEVELOPMENT Department of Building Engineering, Energy Systems and Sustainability Science A review of cooking technology around the world and the potential of solar cooking Martxel Lizaso 2020 Student thesis, Advanced level (Master degree, one year), 15 HE Energy Systems Master Programme in Energy Systems Supervisor: Björn Karlsson Examiner: Mattias Gustafsson Abstract This report studies the importance of solar cooking when moving towards a more sustainable and egalitarian future. The problems regarding its implementation, in fact, technological, social and economic problems, are presented. A historic overview is offered as well as the theory behind the technology. After studying the current situation concerning cooking, different devices have been analysed and considered, from small ones suitable for households to bigger ones for institutions. Furthermore, several backup systems are also proposed aiming to obtain an ideal Integrated Solar Cooker (ISC). Possible hybrid systems have also been evaluated during the work. Furthermore, state-of-the-art technology in Thermal Energy Storage (TES) is also commented and taken into account for the most efficient combination of technologies. Several photovoltaic kitchens are mentioned in this report as well. Two main conclusions have been drawn: trying to solely rely on the sun is a mistake and the ideal and universal ISC does not exist. Other factors besides the income are determinant when choosing an energy source, therefore, a thorough investigation in every particular case is completely necessary for a successful implementation of an ISC. However, the countless devices available make the adoption of solar technology possible in every situation, helping to achieve some of the Sustainable Development Goals. Keywords: solar cooking, thermal energy storage, Phase Change Materials, energy consumption cooking, institutional cooking, energy sources cooking. i Preface First of all, I would like to express gratitude to Stefan Karnebäck, from Engineers Without Borders Sweden, for introducing me to the amazing world of solar cooking and for providing me with valuable knowledge and help throughout the course of this work. He was the one who proposed the subject of the thesis, and even though in the beginning I was sceptical about solar cooking, after our first meeting I realised that it is a really powerful technology capable of changing millions of people’s lives. I also wish to thank Prof. Björn Karlsson, my supervisor from University of Gävle. I would like to express thanks to Tamera Peace Research and Education Center and to Sunseed Desert Technology for the online meetings in which they have kindly provided information about their systems as well as answered all of my questions. This work would not have been possible without the constant support and encouragement of my family and friends, who have always been an important pillar in my life. Finally, I could not miss the opportunity to express my most sincere gratitude to Helena Bergman, a really close friend of our family, who has always been ready to help since I told her I was coming to Sweden. She has solved all the inconveniences I have faced during my stay in this beautiful country. ii Nomenclature Abbreviation and Acronyms Letters Description ASABE American Society of Agricultural and Biological Engineers EU European Union INR Indian rupee IR Infra red ISC Integrated solar cooker/cooking ISSBH Improved small scale box hybrid LCC Life Cycle Cost LHTES Latent heat thermal energy storage LPG Liquefied petroleum gas MNRE Ministry of New and Renewable Energy PCM Phase change material PNG Pressurised natural gas PSC Parabolic solar cooker PV Photovoltaic SBC Solar box cooker SCI Solar Cookers International SDG Sustainable development goals SFSC Small family solar cooker SHTES Sensible heat thermal energy storage SSB Small scale box iii SSBH Small scale box hybrid TES Thermal energy storage UNHCR United Nations High Commissioner for Refugees USD United States Dollars UV Ultra violet VIS Visible WHO World Health Organisation Latin Symbol Description Unit A Area m2 c Specific heat capacity kJ kg-1 K-1 F1 First figure of merit K m2 W-1 F2 Second figure of merit - h Convection coefficient W m-2 K-1 I Solar irradiance W m-2 m Mass Kg P Power W r Reflectance - R Thermal resistance m2 K W-1 T Temperature ºC or K t Time S iv Greek Symbol Description Unit ɛ Emissivity - α Solar altitude / Absorbance º / - Δ Difference - θz Zenith angle º σ Stefan Boltzmann’s constant W m2 K4 휏 Transmittance - v Table of contents 1 Introduction ................................................................................................ 1 1.1 Background........................................................................................... 1 1.2 Aims and limitations ................................................................................ 3 2 Theory ...................................................................................................... 5 2.1 Solar radiation ....................................................................................... 5 2.2 Properties of materials.............................................................................. 8 2.3 Efficiency of solar cookers ........................................................................ 11 2.4 Thermal Energy Storage (TES) ................................................................... 13 3 Method .................................................................................................... 15 4 Results and discussion ................................................................................... 16 4.1 Current situation ................................................................................... 16 4.2 Household cooking ................................................................................. 20 4.2.1 Solar technology .............................................................................. 20 4.2.2 Backup system ................................................................................ 35 4.3 Institutional cooking ............................................................................... 37 4.3.1 Solar technology .............................................................................. 37 4.3.2 Backup system ................................................................................ 41 5 Conclusions ............................................................................................... 45 5.1 Study results ........................................................................................ 45 5.1.1 Households .................................................................................... 45 5.1.2 Institutions .................................................................................... 47 5.2 Outlook .............................................................................................. 49 5.3 Perspective .......................................................................................... 49 References ....................................................................................................... 51 vi Figures index Figure 1.

  • A Stand-Alone Parabolic Dish Solar Cooker for African Conditions
    A Stand-alone Parabolic Dish Solar Cooker for African Conditions by Omotoyosi Onalapo Craig Thesis presented in fulfilment of the requirements for the degree of Master of Engineering (Mechanical) in the Faculty of Engineering at Stellenbosch University Supervisor: Robert Thomas Dobson December 2015 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: 23 November 2015 Copyright © 2015 Stellenbosch University All rights reserved Stellenbosch University https://scholar.sun.ac.za Abstract The reduction in the availability and the ever-increasing prices of fossil fuels, as well as the expensive and insufficient electricity supply, are some of the reasons explaining why the public awareness of the use of alternative cooking methods has increased in recent years. In most rural areas of Africa, the use of wood is even more preferred for cooking than either fossil fuel or electricity, and this has led to deforestation in many areas. However, the time spent on wood collection by women, who often walk kilometres under scorching hot, sunny conditions, can be utilised better in more productive activities. Most of those lacking access to convenient cooking methods live in places with good solar resources and where solar cookers would thrive if developed.

  • Solar Cooking – Background Information
    Solar Cooking – Background Information Solar Power There are two types of solar power; • Photovoltaic solar power: the energy created by converting solar power into electricity using photovoltaic solar cells (solar panels) • Solar thermal energy, or direct solar power: the energy created by converting solar energy into heat. Solar cooking does not require any electricity but uses solar thermal energy to cook the food. This means that you can use a solar oven anywhere that has lots of sun. Solar Cookers Solar cookers are used around the world to cook food and pasteurize water for safe drinking. They use a free, renewable energy source and do not pollute the environment. Solar cookers are particularly useful when other sources of fuel are unavailable or to prevent the use of fossil fuels. There are different types and variations of solar cookers but the basic principles of all solar cookers are: 1. Concentrating sunlight: Foil, mirrors, or reflective metal, is used to reflect the sunlight so that it is concentrated and the energy is stronger. 2. Converting light to heat: Parts of the inside of the cooker are colored black. Black surfaces absorb and retain heat, which is important for keeping the cooker hot. 3. Trapping heat: Isolating the air inside the cooker from the air outside the cooker makes an important difference. A plastic cover creates a greenhouse effect within the oven to make sure that the heat is allowed in but can’t escape out. The Environmental Benefits of Solar Cooking Solar cookers prevent deforestation. Cooking is the main source of demand for wood fuel worldwide, and can be a major cause of deforestation.

Student Objective The student: Key Words: • understands how the Sun’s radiation, conduction as heat, can be captured and used convection • given a solar oven, can explain what glazing makes it work and how to improve insulation on the design parabolic • will construct a solar cooker radiation following a given set of plans. reflector solar collector Materials (construction): solar thermal • use materials list for type of cooker thermal energy selected thermal equilibrium • Laboratory Manual Materials (cooking): Time: For each group: 1 - 2 class period(s) to build oven • oven thermometer, or thermometer 1 class for cooking that has a range to at least 300oF • pot holders • disposable aluminum cooking pan (“brownie” size works well) or clear glass covered casserole Background Information: A solar cooker is a type of solar thermal collector. It “gathers” and traps the Sun’s thermal (heat) energy. Heat is produced when high frequency light (visible and ultraviolet) is converted into low frequency infrared radiation. Ultraviolet and visible light easily pass through glass, however when they strike a darkened surface they are converted into long wave infrared radiation (heat). The glass (called glazing on a solar collector) traps these long waves. For example, on a sunny day, your car with the windows rolled up becomes a solar collector. The glass lets in the Sun’s energy, traps the thermal energy, and the air inside your car becomes hot. As more light enters the car, the air gets even hotter, until we say that it feels like an oven inside.

  • Design and Realisation of a Parabolic Solar Cooker
    Int. Symp. On convective Heat and Mass Transfer in Sustainable Energy April 26- May 1, 2009, Tunisia DESIGN AND REALISATION OF A PARABOLIC SOLAR COOKER M. Ouannene, B. Chaouachi, S.Gabsi Research Unit: Environment, Catalysis and Analysis of Processes National School of Engineers of Gabes (E.N.I.G) - Omar Ibn ElKhattab Street -6029 Gabes- Tunisia. ABSTRACT The sun’s energy is really powerful. Solar energy is renewable and it’s free. We can use it to make electricity, to heat buildings and to cook. The field of cooking consumes many fossil fuels such as gas and wood. Million people cannot find enough gas and/or wood to cook, so using solar cookers is a good idea. During this work, we designed, built and studied a parabolic solar cooker. The characteristic equations and the experimental results are given. Keywords: Solar energy, parabolic cooker, realisation and experimentation. INTRODUCTION Solar cooking is a simple and own technology. Nichols [1993] has shown that the concept of solar cooking began over 220 years ago and was used by the French Foreign Legion starting in the 1870's. It makes possible to reduce the costs of cooking and does not employ any raw material expensive or polluting. Moreover it has a slow cooking; the food is not degraded and preserves all their nutritional and gustatory qualities. All solar cookers work on the principle of concentrating the direct solar rays to raise food or water temperatures to cooking. Cooking temperatures begin at about 65°C although temperatures of 120°C to 200 °C are preferred. Various designs of the solar cookers were studied in order to optimize their performance.

The performance of a solar thermal energy storage system using Lapland granite rock fragments 2-4 cm in diameter were assessed using a scaled-down model. The thesis deals with a selected medium that absorbs and stores solar heat during the day time and releases it when the sun was not shining. A storage rock bed of 5.89 kg with 30 cm x 30 cm base area and 6 cm thickness was placed at the bottom of a solar cooker and painted with black color to increase thermal absorption. The overall performance of a solar cooker i.e. the temperature with and without thermal energy storage (TES) materials was moni- tored for 20 hours. Solar energy is collected for 4 hours and the solar cooker temperature change was studied while solar radiation was zero. When TES materials were used the temperature was above 40°C for 3 hours and 30 minutes; however, without TES materials the solar cooker retain the heat for only 45 minutes. The average of solar radiation re- ceived over a specified period of time during 13:00 to 17:00 was estimated 798KJ.
