  1. Improved Jiko By Arsene de Conde, Tyler Eck, Joseph Hirneisen, and Kevin Meinert

  2. Problem Statement • There are large populations of people in the world with limited access to a safe and efficient means of cooking meals.

  3. Mission Statement • We plan to design an efficient, safe, and low-emissions cooking system that will allow millions of people in the world to safely cook their meals for an affordable price

  4. Criteria to be Met • 50% more efficient than existing models • 50% less fuel use • Economically viable • Culturally appropriate • Cost-efficient

  5. Design Concepts

  6. Design Concepts (cont’d)

  7. Our Design

  8. Our Design (cont’d)

  9. How We Met the Criteria • Fuel Use • Insulation • Vents • Emissions • Insulation • Economically Viable • Straw-Clay Insulation can be made in Kenya • Recycled mild steel from Kenya • Cost-efficient • Made locally • Straw Clay • Mild steel • Culturally appropriate • Standard Jiko is already in use in Kenya • Fuel source can be almost anything, so it can be used essentially anywhere

  10. Additional Benefits • Improved cook time due to being more energy efficient • Easily adaptable • Relatively portable • Durable • Adjustable heat • Materials readily accessible • Safe

  11. Business Plan • All raw materials can be obtained in Kenya at low prices • The straw clay insulation can be made from the clay in the mud due to its relatively high clay content • The mild steel comes from recycled parts and is already being used in Kenya • Entire unit could be made in Kenya, which would lower shipping costs as well as the cost of materials

  12. Cost Analysis • Mild Steel • 5.07 ft2 needed • Costs $1/kg, which means our design need about $9.40 worth of mild steel • Straw-Clay insulation • Costs $50/ton • Cost for stove is less than $1.00 • Total cost for our cook stove • Approximately $10.40

  13. Cultural Impacts • Positive • Efficient cooking system • Less fuel use • Less emissions • Safe • Will cost less money in the long run due to its durability • Negative • Still uses biomass, which could eventually lead to deforestation in some areas • Mild steel is prone to corrosion • Stainless options are available, but would result in a price increase • A little more expensive than the current models

  14. Conclusion • We believe that we have a pretty solid design that meets all of the criteria. Our design could be made totally in Kenya from recycled parts, thus minimizing the cost. This would greatly help millions of people who have little or no access to a stove, which means that we have achieved our goal and satisfied our mission statement.
