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 $4.10 for an individual jiko

Sale price $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
