The Problem
Objectives
Background
Possible Solutions
Our Plan
Final Solution
Conclusion
Greatest Health Risk of Children
Under 5 in Developing Nations
Smoke Inhalation from Indoor
cooking
Biofuels lead to deforestation
Low income levels
Prefer to cook indoors
Design a low cost, sustainable, and culturally
appropriate cooking system for use by poor
and marginalized people in the developing
world.
The system should utilize an appropriate fuel
source.
A business centered on the fabrication of such a
system should be considered to serve a market
of people who earn less than $2/day.
Primary Market
Rural Kenyans
Secondary Market
Urban Kenyans
Other Developing Countries
The cooking system must be marketable and
profitably by the CYEC
Reduction of harmful emissions
Low cost to buy
Durable
Easy to use
Users
Shell
CYEC
Manufacturers
Factories, marketers, transport, supply chain
Want a cheap efficient cooker
A durable product
Ventilation seems to not be a problem
Mass production must be cheap
Product must be reliable
Need capital to start mass production
Cooking is seen as a private matter
Cheaper is better
Massive corruption
Woman are the target audience
Fuel sources such as wood are running out
Harmful things like dung are being used
Advertising
Keep costs low
30% markup on sales
The CYEC youths are capable of
manufacturing

Majority of Kenyans already use the Jiko
Current Jiko Offers: …
Hot-Dip Galvanizing
Zinc or Aluminum
Requires:
Galvanizer kettle
Zinc- $2.354/Kg
2Zn(s) + O2(g) 2ZnO(s)
ZnO(s) +CO2(g) ZnCO3(s)
Oxidation only proceeds until a small layer
of ZnCO3(s) is produced. This protects the rest of
the zinc and other metals from further Corrosion.
Will last up to double is previous life span if
not more guaranteed.
This just the simple new improvement will:
Increase life span of Jiko
More durable Jiko
More efficient in long run
Production of the new jiko
A simple process which can be easily learned
Will profit from the sales of the modified jiko
Production Costs
Sale price
$4.10 for an individual jiko
$5.33
In order to create facilities in which the Jiko can
be massed produced by the CYEC, a minimum
of $10,000 must be gained from charitable
sources
Customers can give their old jiko’s to the CYEC
and receive a discount on a new CYEC made
jiko
The handed in jikos will be recycles saving
costs
