2. The Problem…
Should cooking be this much work?
Should it use this much wood?
Should cooking make this much
smoke?
3. The Scope of the Problem
2.6 billion people still cook on open fires or primitive cookstoves…
Over 80% of people in sub-Saharan Africa rely on biomass as a primary fuel,
and less than 25% of these have improved cookstoves.
25% of black carbon emissions world wide is attributed to traditional cooking,
and black carbon is responsible for nearly 20% of the planet’s warming.
Household air pollution is responsible for 4.3 million premature deaths
worldwide every year ; 80% are women & children.
8. Burn Design Lab – Our Mission:
To improve lives and the environment in the developing world
through research, design, & development of outstanding
cookstoves and fuels.
.
Improve lives & the environment:
reduce health hazards, improve
household safety, preserve both the
regional and global environment, &
reduce fuel costs.
Develop: User Research, Applied
Research, Design, Prototyping, Testing,
& Conducting Field Trials
Outstanding: On the leading edge of
affordable appropriate technology
Fuels: renewable biomass derived
solid fuels
9. Preliminaries / Groundwork
It’s not just about
cookstoves…
It’s about the stove
The fuel
The pot
And the user
10. Preliminary / Groundwork
Our goal is to have a
positive impact –
on people’s lives
on the environment.
Performance x Adoption x Durability x
Scale = Impact
What is 10% improvement worth?
1.10 x 1.10 x 1.10 x 1.10 = 46%
improvement in impact
Improvements in performance,
adoption, & durability will tend, over
time, to increase scale.
11. Examples of what we do
Developed the Eko-Estufa cookstove
for Cemex in 2012.
CEMEX committed to install 100,000
stoves in Mexico and Guatemala by
2017.
People benefitted: ~500,000.
Latin America
12. Another example - Jikokoa
Based on Independent Field
Tests:
• Reduces fuel consumption
by 45% and emissions by
61% compared to current “
improved stove”
• Saves users $100 –
300/yr.
For sale throughout Kenya
Current Production by Burn
Manufacturing 10,000 stoves
/ month
13. Examples of what we do –
Kuniokoa (East Africa)
Developed Kuniokoa under
DOE grant in partnership with
the University of Washington.
50% wood fuel savings over
traditional cooking.
Pilot production of 50 stoves
Funding received from Acumen
by Burn Manufacturing Corp. to
pay for production tooling &
equipment.
Full production scheduled for
November 2016
14. Project Update - Kuniokoa
Design is complete for G1 (1st
Generation) Kuniokoa. Users are very
happy with the stove.
Completed field emissions &
performance tests in July.
Laboratory tests conducted at
Lawrence Berkeley Labs
Designing & building tooling for full
production
Factory full production scheduled for
November.
15. How?
By partnering with local manufacturers and
implementers throughout the cookstove
development process.
16. By Partnering with Universities on cookstove
research, modeling, testing, and design.
How? – cont.
18. User Research – cont. Focus Group Discussions & Home Placement
5 different geographic areas in Kenya.
total of 213 participants, 18 – 58 years of age
Firewood primary fuel
Socio-Economic Status: $10 - $100/month
Households of 2 – 8 persons
35% of cooks purchased firewood; 65% gathered.
Half were using some type of “improved” cookstove
at the time of the study.
.
5 prototype cookstoves developed by
UW / Burn Design Lab together with
4 commercially available cookstoves
were used in the study
20. Results – cont.
For those FGDs participants
who purchased firewood, the
average price paid was 370
KES/week (~ $3.70/wk)
An improved cookstove that
sells for $40 and saves 50%
of fuel use, could pay off in
6 months or less for 80% of
the participants in this study
User Research – cont.
21. User Research – cont.
Fuel burned by users is roughly three times as large as that typically used for
WBT’s in the lab.

22. G1 Stove Development
32 stove prototypes and 80+ configurations
Total number of tests: ~500
Innovations have focused on PM reduction and user aspirations
23. G1 Stove Development
Challenge: Boil Over
When cooking it is not uncommon for liquids to boil over out of the pot and onto the
stove. When this happens the liquid can get into the top of the stove (cone deck) the
sides, and into the combustion chamber. Since the combustion chamber already
experiences the most sever conditions, liquids from boil over add a corrosive,
shortening the life of the combustion chamber. To avoid this, a “boil over gutter”
(BOG) was formed into the cone deck.
Cone Deck without BOG Cone Deck with BOG
