|

Experimental Procedure
|
||||
Burn constant amount of fuel using both cooking methods (Open fire vs IAP Reduction Unit)
|
||||
Measure weight of particulate residue from the smoke collected by HEPA filter
|
||||
Measure concentration of Carbon Monoxide (CO) and heat at set time intervals.
|
||||
Compare weight of fuel residue, CO concentrations and heat generated..
|
||||
An infrared temperature thermometer at the different parts of the unit with respect to time
|
||||
A simple chimney with filter paper is designed to measure the weight of carbon and particulates per unit time.
|
||||
A CO meter is used to measure the concentrations of CO present throughout the burning process
|
||||
Determine if there a significant difference in IAP and combustion efficiency between the traditional and IAP Reduction cooking system

<h2 class="fw-bolder py-4">WHO Report</h2>
|
||||
<p class=".fw-bold lead">
|
||||
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.

<p class=".fw-bold lead">
|
||||
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.)
