Situational Background Goals Assumptions Constraints Current cooking systems Possible solutions Proposed solution ◦ Design ◦ CAD prototype ◦ Specifications
System to be implemented in Rural Kenya Nyeri is the initial focus Sponsored by Shell Energy Company Aided by Children and Youth Empowerment Center (CYEC) Subsistence farmers
Design a new cooking system to implement in Nyeri Kenya ◦ More fuel efficient ◦ Faster cooking time ◦ Culturally acceptable ◦ Low cost (under 20 USD)
Concern exists towards family health Natives willing to spend more for a superior product Food culture will not drastically change Interest in creating a new industry
Cost Weather/environment Transportation Technology Culture
Subsistence farmers in Rural Kenya Low income (<$1 per day) Large families No economic escape
Jiko woodstove (Rural Kenya) Wood gasifier stove (Rural India) Envirofit (India) Gas stove (Urban areas)
Two models ◦ Domestic or industrial Difference of size ◦ Domestic widely used in Nyeri and Kenya Very inexpensive (~2-4 USD) Hand-made
Small size Made easily Cheaper than Jiko (~0.25 USD) Hand-made
US-made Efficient burning Faster cook times Expensive (~50 USD) Durable Consistent
Expensive More modern Fast cooking time High energy/high heat Less than 10% have LPG
Parabolic Solar Cooker Solar box cooker Rocket stove Biomass stove Wood gasifier
Fueled primarily by wood or biomass Solar energy to aid efficiency System based off the Jiko ◦ Price range ◦ Increased craftsmanship Parts can be assembled locally, cheaply ◦ Estimate ~8-12 USD
Insulated Fire chamber ◦ Ceramic insulation Stove top ◦ Steel holders Solar reflection panels ◦ Aluminum paneling Burner door ◦ Cleaning, better efficiency
Stove dimensions ◦ 20-24”h (top of panels) ◦ 14” base diameter ◦ 10” stove top ◦ 9” x 5” stove door Cost ◦ Stove based on Jiko models in use $4-6 ◦ Solar paneling $4-6
