  2. Abstract • Current Kenyan stoves create harmful emissions, which is leading to death by smoke inhalation. Therefore we created a stove that is a revision of the original Kenyan Jiko that will now consist of an aluminum coating shell, a 1:1 ratio of clay to non-clay, and will run on biomass fuel, wood, or charcoal. By making these specific changes, we will decrease emissions, fuel used, and cooking time.

  4. Description of Task • Problem Statement • Smoke Inhalation • Inefficient Stove Emissions • Poor Economy • No Technological Advancements • Cultural Boundaries • Reluctant to Lifestyle http://www.solutions-site.org/kids/stories/KScat2_sol60.htm

  5. Description of Task • Design Specifications • Decrease emissions by 50% • Decrease fuel used by 50% • 50% faster cooking time • Economically viable • Appropriate for the culture http://www.solutions-site.org/kids/stories/KScat2_sol60.htm

  6. Design Approach • Consumer Needs Assessment • Efficient • Durable • Safer Cooking System • Easy to Use • Affordable http://www.solutions-site.org/kids/stories/KScat2_sol60.htm

  7. Design Approach • Concept Generation • We analyzed all of the stoves by comparing each stove to each one of the consumer needs Jiko Solar Cooker Solar Heated Grill Smokeless Cooker Gassifier Stove Envirofit Stove Cooker http://gorilla.wildlifedirect.org/files/2009/09/jiko-kenya.JPG http://solarworldea.com/wp-content/themes/solarworld_v1/images/projects/solar_cooker2.jpg http://web.tradekorea.com/upload_file/prod/emp/200906/oimg_GC00024923_CA00307534.jpg http://www.trailjournals.com/images/gear/bushbuddy13.jpg http://cache.gizmodo.com/assets/resources/2007/04/solar_grill_show01_w460.jpg http://iapnews.files.wordpress.com/2009/07/envirofit-stove2.jpg

  12. Final design • Stove Type: Jiko • Coating: Aluminum • Clay and Metal Ratio: 1:1 Clay to Non-clay • Fuel: Biomass, Wood, Charcoal

  15. Engineering Analysis • Working Mechanism • Place fuel on in upper chamber • Light the fuel • Combustion occurs • Air will flow through bottom where there is a slit and door • Fuel burns • Heats food in pot on top of Jiko • Ashes fall through holes in clay to bottom • Recover waste http://alaninkenya.org/wordpress/wp-content/uploads/2008/07/jiko_na_githeri.jpg

  16. Engineering Analysis • Cost Analysis • Cheap long lasting aluminum coating – aluminum is recyclable and also is durable. • 1:1 ratio of clay to non-clay – this is the most durable form of clay and it can with withstand the most heat. • Biomass Fuel – get a lot for a low cost because of its high energy generation, it is also a prevalent resource • Wood Fuel – very prevalent resource therefore cheap • Charcoal – where biomass and wood are scarce, charcoal is the cheapest substitute • Business – current builders of Jiko can still produce without going through a vigorous learning process • The cost will be between 4 and 5 dollars

  17. Summary and Conclusions • Redesigned Jiko • Social • Little change • Environmental • The fuel used will decrease emissions • Recycled materials • Economic • Within price range • Sustains and provides new employment • Changes • Aluminum coating will reduce rust • Biomass, Wood, Charcoal • 1:1 ratio of clay to non-clay
