Conclusion

+

+ The results disproves the null hypothesis in the tested configuration. The clean cooking +apparatus does reduce IAP. Therefore, the next step will to be improve the design of the IAP +Reduction Stove so that it best suits the people who need it the most. The next step will be +building a full-scale prototype with the hood and chimney to test the cut and fold patterns +and the minimum gage steel that can be used. +

+

+ After building the prototype it is then installed in a unit dwelling with a steel roof or thatched +roof to determine its usefulness and efficiency in the real world. +

+

+ I will also look for partners to create the units and a website where those who have installed +a unit can upload their experiences and suggested improvements (and their improved layout +patterns). This adopts the highly-successful approach of crowdsourcing, whereby products +are continually improved by their users. This enables the basic approach to be refined for +different climates, cultures and lifestyles. Examples of this include Waze, which collects +traffic data for use by everyone, MacDonalds and Starbucks, who collect user ideas to +improve their products, and the publicly maintained software UNIX operating system, +(Berkeley Standard Distribution - BSD), and its descendent, Linux, which is installed on over +32.8 million systems and on 1.6 billion Android phones worldwide (99 Firms 2022). +

Design of Combustion Chamber:

+

+ The combustion chamber is designed in a +rectangular prism shape. In the combustion chamber fuel (wood pieces) are +combusted. It was observed that inner chamber became red hot. To reduce +the heat losses from inner chamber, a jacket of coarse sand and heat +resistance refractory material was added (Fire Clay). As shown in the figure +to the right. +

The Clean Cooking System has two components:

+
    +
  1. Stove “Cooker” to burn fuel more efficiently and + reduce emitted smoke.
    2. +
  2. Chimney and hood, to eliminate fumes from + dwelling. The chimney is isolated from the roof + by a 2nd outer pipe. Nails are used to isolate the + chimney pipe from the insulating pipe and the roof.

The Inexpensive IAP Reduction System

+ +

+ Woman Cooking +According to the World Health Organization (WHO), around 2.6 billion people +cook and heat using polluting open fires or simple stoves fuelled by kerosene, +biomass (wood, animal dung and crop waste) and coal (Air Pollution Data Portal, +n.d.). This generates high levels of health-damaging Indoor Air Pollution +(IAP), such as particulates, tar and carbon monoxide. Because women are +primarily responsible for cooking and raising young children, both are +disproportionately affected by IAP. For example, the World Health Report (2002) +states that in developing countries among the poor, Acute Respiratory Infection +(ARI) is one of the leading causes of childhood mortality (under 5) and is +responsible for up to 33% of all ARI cases. IAP also adversely affects Zimbabwe +because of the number of people who live in poor, rural regions. (Rural +Population (67% of Total Population…2020) - Zimbabwe | Data, n.d.). +

+

+ A second problem caused by open or traditional heaths is the inefficient use of fuel. Past efforts to +reduce IAP have focused on efficient combustion but have not necessarily focused on thermal efficiency +of the overall cooking and heating process. As a result, a significant portion of the fuel's energy is lost, +leading to increased levels of deforestation. In parallel, people who are faced with the challenge of +indoor air pollution are from low-income communities which makes it very difficult for them to afford +expensive clean cooking stoves. Most of the existing solution focus only on reduction of Indoor Air +Pollution, but fall short on distribution the solution to billions of people who need it. +

+

+ traditional stove +Because of the above issues, the engineering goal of this experiment is to create pattern designs of creating an +affordable, simple, and efficient cooking system whose design is based on origami. Origami is the Japanese +technique of creating complex 3-dimensional objects from flat sheets of paper. All that is needed to make a well +known object such as a Crane, Cube or Lion is the pattern and a piece of paper. Likewise, the clean cooking +system's components will be fabricated from flat metal sheets using simple folds and cuts, enabling them to be +made worldwide without complex fabrication techniques. Additionally, if a component;s pattern is known, it can +produce it using locally available material and tools. This reduces or eliminates funding and production +bottlenecks that have limited the impact of prior efforts when attempting to produce and distribute billions of +units worldwide. +

+

+ Since many regions that suffer from indoor air pollution also have electricity shortages, the practicality of using +the thermoelectric chips to generate electricity from the cooking stove's waste heat is evaluated. Its cost per watt +hour is compared to alternatives such as simple solar panels with local storage (batteries or super capacitors.) +

For the experimental results the IAP reduction cook stove was compared to an open traditional fire in terms of + temperature carbon monoxide concentration and weight of particulates and tar released.
