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.

15. Engineering Analysis Working Mechanism 1) Place fuel on in upper chamber 2) Light the fuel 1) Combustion occurs 1) Air will flow through bottom where there is a slit and door 3) Fuel burns 4) Heats food in pot on top of Jiko 5) Ashes fall through holes in clay to bottom 6) 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
