Chad
A loose association of five German
nongovernmental organizations
(NGOs) has formed the PapiTchad
Work Group to promote the "Papillon"
solar cooker in Chad and evaluate the
results. The Papillon is essentially a
parabolic cooker consisting of two
reflective "wings" with a gap in
between to allow for comfortable use
by the cook and folding of the
reflectors for transport and storage.
The work group, in conjunction with a
Chadian instructor, has provided construction courses for local craftsmen.
PapiTchad is partnering with the Chadian Association of Volunteers for
Progress and the Environment. Contact Jürgen Marquardt, Lernen - Helfen -

Derk Rijks of the KoZon Foundation
began a small demonstration project in

3. northern Chad at the Iridimi camp for refugees from the Darfur region of
Sudan. Mr. Rijks took 100 "CooKits" — panel-type solar cookers developed
by Solar Cookers International — to the camp. The project tested whether
food donated to the refugees by the United Nations World Food Programme
could be solar cooked and whether the refugees would accept solar cooking.
Three C ooK i
t trai
ners from N ’
D jam ena, C had — Marie-Rose Neloum, Martine
Missal and Esther Ndoroumta — aided in the training. The refugee women
were enthusiastic! They cooked rice, maize and sorghum porridge, legumes,
dried fish and okra sauces. Staff members from the United Nations High
Commissioner for Refugees in Geneva were very helpful. Efforts are being
made to expand the program. Photo shows Darfur refugees hand-producing

Eritrea
The organization Solar Cooking Eritrea
Netherlands (SCEN) began working in
Eritrea in November 2003 as a
member of the Working Group Hagaz
Eritrea. In January 2005 SCEN became
an independent foundation. During
three visits to Eritrea the group,
working with the National Union of
Eritrean Women, has introduced the
CooKit solar cooker to many women in
the Anseba region. Work has begun to
enable local production of CooKits. Solar cookers have also been introduced
in a camp for displaced persons at Adi Keshi in the Gash Barka region. SCEN
shares information with the KoZon Foundation, another Netherlands-based
organization with years of experience promoting solar cooking in West
Africa. SCEN is headed by Mrs. Clara Thomas. Contact Ms. Janine Pater by e-

Kenya/USA
SHARE — the Society for Hospital and
Resources Exchange, based in New York,
USA — has provided a giant Villager Sun
O ven® to the K akel
o w om en’
s group in
Oyugis, Kenya. The solar oven, made by

4. Sun Ovens International, is capable of baking 100 loaves of bread per hour.
"The oven can pasteurize water for drinking as well as bake bread and other
bakery items," SHARE reports. "This frees women from the job of wood-
gathering for fuel, [which takes] up to four hours a day, and it saves the
cost of purchasing charcoal or wood if the women cannot find enough wood.
Solar cooking keeps women and children out of the smoke-fi
l
l
ed huts … that
cause extremely high inci
dence of severe respi
ratory di
seases … and eye
problems. Solar cooking also avoids the danger of children falling into open
fires and suffering severe burns. "Since the arrival of the big sun oven,
people have been visiting it from surrounding districts and missions and are
filled with hope," SHARE reports. "Thirty more women have joined the group
to learn how to [solar] bake bread." Many members of the Kakelo group
take care of AIDS patients and AIDS orphans, so the financial, health and
nutrition benefits are especially important.
Malawi
In the first year of his latest solar cooking project, Mr. Hosana Nyirenda
hoped to train 30 women to make and use solar cookers. Ultimately, 42
women and eight men were trained. (Forty of them learned how to teach
others.) Sixty-seven solar cooking demonstrations were conducted, raising
solar cooking awareness of some 4,500 adults and children. A few
communities are considering solar cooker projects of their own. Mr.

The Association of Handicapped Women (AMAFH) has been organizing solar
cooker training for its members. Twenty women participated in the first
training session. They reported that the lightweight "CooKit" solar cooker is
easy to handle and that with solar there is less risk of burns. They say that
solar cooking can put handicapped women in the same range as other
women in running their own households.
AMAFH learned about solar cooking when they saw a television show about
the Association of Women Engineers (AFIMA) demonstrating solar cookers.
AMAFH contacted AFIMA to arrange training for their members, funded by a
small grant from Handicap International. They were so pleased with solar
cooking that they began organizing more workshops for their members, with
assistance from the KoZon Foundation in the Netherlands. Contact Kozon

Nigeria
Mr. Joseph Odey of the Kainji Lakes region reports that he has built and
distributed 290 solar cookers in the past few years. In addition, 152 people
were taught to make and use their own solar cookers. Demonstrations have
been given in 18 villages. Before promoting, Mr. Odey built and tested his
own cooker from instructions published by Solar Cookers International. His
first solar meal was rice, but he soon moved on to cooking stew, cake, bread
and other foods. Mr. Odey uses the following locally available tools and
supplies: cardboard, aluminum foil, glue, knife, scissors and tape, as well as
black pots for cooking in. Though he does sell some cookers, he pays
production, distribution and travel expenses. "The beneficiaries confirmed
that the [meals] from the cookers are quite palatable, but not for someone
who wants food in a hurry," Mr. Odey reports. Contact: Joseph Odey, P.O.

Mugumu, Serengeti District, Tanzania.
Scheffler reflectors are large parabolic
dishes that are often used to heat a cooking medium (such as water to make
steam) that is circulated to one or more indoor cooking stations. This is a
smaller version. Mr. Charles Onyango-Oloo of AltEner says the new design is
user friendly since "the port is mounted on one side and not in the middle of
the reflector dish." AltEner is currently developing a 1.5-square-meter,
manually tracked Scheffler cooker. Contact: Charles Onyango-Oloo, AltEner

Elizabeth Mpofu received training in solar cooking five years ago from Barby
Pulliam, a Girl Guide and Solar Cookers International volunteer. Ms. Mpofu
reports that her group has trained 500 women how to solar cook and offered
them each a solar cooker. Ms. Mpofu has also promoted solar cooking in
primary and secondary schools. "Each year," she writes, "we are doing an
evaluation to assess the problems, achievements and innovations the
participants are experiencing. The major stumbling block is lack of resources
to expand the program to other communities." Contact: Elizabeth Mpofu,

Canada/Haiti
Communities in Partnership, a Canadian organization that promotes solar
cooking in Haiti, has introduced a new twist — the "K yoto Tw i
st." C anada’
s
government is encouraging its citizens to fight global climate change by
reducing individual emissions of greenhouse gasses by one ton per year.
Solar cookers in developing countries that displace the use of firewood save
an estimated one to two tons of greenhouse gasses per year. The Kyoto
Twist — nam ed for the w orl
d’
s greenhouse gas reducti
on treaty — enables
Canadians to buy a solar cooker for a family in Haiti. The Haitian family gets
immediate relief from firewood scarcity, high fuel prices and smoky kitchens,
while the Canadian chalks up at least a one-ton reduction in greenhouse
gasses. Contact: Jack Anderson, Box 191, Lund, BC V0N2G0, Canada. E-

The Celestina Pérez de Almada Foundation continues to expand its solar
program and to gain new allies. In March, the foundation began cooperating
with Essen, a company that manufactures cooking pots that work well with
parabolic-type solar cookers. A demonstration was held in Asuncion where
popular local foods were solar cooked. Ms. Graciela Stanchuk, an
international manager for Essen, pledged that the company would pursue
further solar cooking tests. The Foundation has also developed a solar

8. energy training program for students and school personnel, to be funded in
part by the Swiss Embassy in Paraguay, and has begun making large
Scheffler reflectors, of which two have already been installed. A Scheffler
dish with 4.5-square-meters of reflective surface is being used to cook fruits
at a juice and jam factory in Clorinda, Argentina. A second dish with 8-
square-meters of surface will power an oven that reaches 250°C. Contact

Inventor Carroll Hampleman reports
that he has designed and constructed
the "Hamp Hi-Tracker," a series of 28
reflecting mirrors that track the sun
throughout the day. Carroll says the
device can be used to cook food, as
well as heat water for various uses.
Two 35-watt, 110-volt reversible
control motors (approximately $13.00
each) provide tracking capability, and
can be powered by household 110-volt
electricity, or by a 12-volt car battery
or photovoltaic cell (inverter required). At 6 p.m. the mirrors automatically
return to their 8 a.m. morning positions and the control motors shut down,
ready for the next day. Photo shows "Hamp Hi-Tracker" pre-heating a hot-

Students at the Rochester Institute of
Technology in New York won a
$10,000 "People, Prosperity and the
Planet" award from the U.S.
Environmental Protection Agency for
their solar cooker research. The award
will fund a project to design solar
cookers that can be mass-produced at
low cost using the capital, labor and
materials that are typically available in
Latin American nations. In early
phases of their research, the students
chose particleboard as the primary construction material because of its
relative low price, durability, insulation values and local availability. The
students focused on three solar box cooker prototypes, including one that
they say requires only about $15 in materials. End users in Venezuela have
tested the prototypes. For more information visit the project Web site:

India
Dr. Anumakonda Jagadeesh develops simple,
affordable solar devices, including food
dryers. He says that solar drying is popular
in India, where people often dry soaked rice,
pickles, salted fish and millet by placing the
food in winnowing baskets and leaving it to
dry in the sun. But food dries slowly in this
manner and is exposed to contaminants like
dust, insects and birds, not to mention
sudden rains. Dr. Jagadeesh designed a
simple solar dryer to overcome these
obstacles. The body of his dryer is a tray-shaped basket made of bamboo or
similar woven material, with slanted sides to accommodate broad sun
angles. The inside is lined with a black, high-density polyethylene plastic
sheet to absorb solar radiation. (Alternatively, the basket can be painted
black and lined with a transparent plastic sheet.) Holes are made in the
sides of the plastic sheet to allow airflow through the dryer. The basket is
covered with transparent polyethylene sheet that is fixed on two sides. The
ends are left unfixed to allow access to the basket. Dryer tests conducted by
Dr. Jagadeesh indicate drying times half that of traditional open-air
methods. Contact Dr. Anumakonda Jagadeesh, Nayudamma Centre for

13. Sunny Solutions enters business phase
By Pascale Dennery, SCI Technical Assistance Director
Two years ago the Sunny Solutions project began
introducing the benefits of solar cookers to people in
the rural communities of Upper and Lower Nyakach, in
Nyanza Province, Kenya. Solar Cookers International
(SCI) worked closely with its community-based
partner, Nyakach Community Development Association,
as w el
las w i
th l
ocall
eaders and w om en’
s groups. A
network of local solar cooker representatives in four
administrative locations of Nyakach provided solar
cooker demonstrations at marketplaces, churches and
other public events, creating widespread awareness of
solar cooking and solar water pasteurization throughout
the area. In April, additional solar cooker
representatives were trained to ensure that solar
cookers are accessible in all fourteen administrative locations.
During the first 18 months of the project, sales of CooKits — S C I’
s panel
-
type solar cooker — reached 635, surpassing normal patterns of uptake for
new technologies and benefiting an estimated 3,600 people in Nyakach and
neighboring areas. When sales reached 500 cookers, the project transitioned
from the introduction phase to the business phase. Seventeen Solar Cooker
Representatives (SCOREPS) work hard to achieve sales; they walk long
distances to visit clients, conduct product demonstrations, collect payments
and provide follow-up services. These seventeen women earn money from
sales and for providing instruction and public demonstrations. Four SCOREPS
are now interested in starting "energy shops" to sell CooKits and related
supplies (pots, lids, cooking bags) as well as offering maintenance and repair
services. SCI collaborates with local providers of micro-credit loans and
small enterprise trainers to help ensure success of these shops.
To further increase access to solar cookers in impoverished areas such as
Nyakach, SCI staff and volunteers in Kenya are testing prototypes of hand-
made CooKits for durability and cooking performance. The hand-made
cookers, with durable Tetra Pak reflective material, could potentially be
made in Nyakach at a lower cost, thus expanding options for Kenyan
consumers as well as further employment opportunities.
Local solar cooking access is good for both sellers and consumers. During
my February visit to Nyakach, a woman named Ella told me her children
enjoy solar-cooked foods so much that there are no leftovers. She has cut

14. her monthly charcoal use from two sacks to less than one, and she can now
afford to have an AIDS orphan live at home with her. Elizabeth, a SCOREP
nicknamed "Mama Solar," said solar cooking helps her family stay healthier
as they eat more nutritious meals, drink pasteurized water, and breathe in
less smoke from cooking fires. I also met Margaret, a woman who solar-
bakes cakes (a rare treat in Nyakach) and sells them by the slice at her
son’
s barbershop. O ther enterpri

income by using solar cookers in small restaurants or investing cooking fuel

cookers truly make a difference in Nyakach, where most people live on less
than one dollar a day.

priorities for 2005-2010: first, spreading solar
cookers to marketplaces throughout Kenya —
growing from the Sunny Solutions project in
Nyakach, Kenya — and, secondly, advocacy for
supportive energy policies in five governments.
Future Review issues will provide updates on
these programs.
Oddly, urgent cooking fuel shortages in many
developing countries are still nearly invisible to
many policymakers, as are the related harmful
impacts on families. This year the United Nations
is again focusing on the Millennium Development
Goals (MDGs), eight goals to combat poverty, hunger, disease, illiteracy,
environmental degradation and discrimination against women by the year
2015. The MDGs state that w om en’

women need better education, opportunities for income generation, and
participation in community development. But none of these is possible until
women and girls are free from the time loss and hazards of fuel gathering,
smoky fires and diseases from unsafe drinking water. Solar cookers advance
all eight MDGs.

explained to callers the difference solar cooking has made in her life. In
addition to using less cooking fuel, Doris appreciates not having to tend a
smoky fire and her family enjoys pasteurized water and tasty meals. Her
children love the aroma and flavor of solar-cooked omena (small fish similar
to minnow). On May 29th Solar Cooker Representative (SCOREP) Jessica

introduced solar cooking to six teachers at Rae Gem Primary School in North
Nyakach. Her husband is very happy that Jessica is one of the top solar
cooker sellers in the area; the benefits of her hard work are apparent within
the family.
Many people listened to the radio programs. Over 100 listeners phoned for
more information and a record 103 CooKits were sold during the month.
Listeners said the radio spots gave credibility to solar cooking and the
businesses run by the SCOREPS.
Rose Kowere was one of the listeners. She is a visually impaired history and
English teacher, with a Masters degree in Special Education from the United
Kingdom. Rose contacted Dinah to purchase a CooKit and receive instruction
in its use. When Dinah arrived at Job Omino Primary School in Kisumu town,
Rose had already gathered nine other teachers so they could learn too. Rose
purchased a CooKit right away; four others also hope to buy CooKits. Dinah
left with a promise to return soon and conduct a solar cooker demonstration
at the school.
So, what can YOU do?
By Kevin Porter, SCI Education Resources Director
Do you remember the first time you cautiously removed a hot pot from a
solar cooker, anxiously opened the lid, and witnessed — with awe — the
steam and scents come rushing out? Amazing, w asn’

gradually, sporadically.

17. To hasten the worldwide spread of solar cookers, the board of directors of
Solar Cookers International (SCI) has made advocacy a high priority. Over
the next few years SCI will work to influence local, national and international
policy-makers to support solar cooker use on a larger scale. You can play an
important role in your own community and beyond. (More or less of these
ideas may be practical for you, depending on where you live, etc.)
S o, you m ay ask, w hat can YO U do? I’

FIRST, PRACTICE AND LEARN
Learn to solar cook and do it regularly. First-hand experience of solar
cooking many foods is invaluable. People will ask, guaranteed!
Develop a basic understanding of solar cooker history and concepts. A good

TEACH OTHERS
Family, friends, neighbors. The simple act of using your solar cooker is sure
to pique the curiosity of family, friends and neighbors. Feed this interest,
literally, by hosting a solarque. Some neighborhoods even have solar
potlucks.
Youth. Solar cookers are excellent devices for teaching about solar energy.
(And hopefully youth that learn about solar cookers become solar-cooking
adults!) Offer to teach solar cooking to students at schools, youth programs,
camps, etc.
General public. Festivals, Earth Day celebrations, religious functions and
other public events provide opportunities to expose large numbers of people
to solar cookers. Grocery stores, particularly natural food stores, may allow
you to demonstrate solar cookers at their store or teach a cooking class.
Note: with advance notice SCI can provide handouts and display materials.

INFLUENCE DECISION MAKERS AND PUBLIC OPINION
Engage the media. Newspapers and broadcast media are sometimes
interested in local stories with an international angle. If you solar cook, they
may wish to report about your experiences and the worldwide potential for
solar cooking and solar water pasteurization. Be sure to send article copies
to SCI for its archives!
Write letters to editors. When you read news stories about cooking fuel
shortages, illnesses caused by cooking smoke and fires, waterborne
diseases, or general drudgery faced by millions of women in developing

18. countries, consider submitting a response that provides insight into solar
cookers as clean, safe, environmentally-friendly tools for cooking food and
pasteurizing water. (See sample, below.)
Contact elected officials. Ask them to support renewable energy technologies
like solar cookers and to help level the playing field by removing unfair
subsidies given to non-renewable energy companies.
SUPPORT SCI AND OTHER SOLAR COOKER PROMOTERS
 Become an SCI member. Your financial support is crucial to our
work, and your thoughtful communications keep us invigorated.
 Spread the word. More support for SCI means more families can
benefit! For example, generous SCI supporter Kent Mein directs folks
to support SCI through his Web site: www-
users.cs.umn.edu/~mein/random.html
Alternative gifts. For your next birthday or holiday consider collecting
donations instead of presents. This works both ways: you can also give
to friends and family by donating to SCI in their honor.
 Volunteer. Many solar cooker promoters need help from time to time.
If you have some spare time you might consider volunteering. You can

19. Further adventures in adapting solar ideas
By Ramón Coyle, SCI Information
Exchange Specialist
Creative people often send their ideas
to Solar Cookers International. Two
recent examples come from India.
Dr. Ajay Chandak of the PRINCE group
says, "There are many enthusiasts
living in cities, and they do not have
adequate space to keep parabolic solar
cookers in the sun. Balconies are
smaller — normally three-feet wide —
while the SK-14 (a popular parabolic
cooker) needs six feet of space." Dr. Chandak built a parabolic cooker that
can be mounted on the parapet or railing of a balcony. A retractable handle
pulls the cooker close enough to the balcony to give access to the pot. The
cooker comes equipped with a manual tracking device that allows the user to
follow the sun from east to west and as it climbs and descends in the sky.
This may not be the final word on solar cookers for balconies, but it is the
first time I have heard of someone attempting to design parabolic cookers
for urban residents in high rise buildings. Contact: Prof. Ajay Chandak,

Trust, Shamgiri, Agra Road, Deopur, Dhule 424 005, Maharashtra, India.

Meanwhile, Sri Sankha Subrha Datta of
West Bengal proposes a new type of
solar box cooker. Details were recently
added to D r. A shok K undapur’
s onl
i
ne
review of solar cooker designs at
http://solcooker.tripod.com/solar8.htm
. Dr. Kundapur writes, "I consider it a
new major design on the scene. It is a
rectangular construction with two
reflectors, making it possible for
trapping maximum solar radiation. For

20. achieving this, the cooker has to be incl
i
ned. … I am sure thi
s cooker
performs better than regular box-type solar cookers with one reflector."
The key feature of this new box cooker is that it is designed to tilt toward
the sun. The Global Sun Oven® — a popular model by Sun Ovens
International — has an adju stabl
e l
eg al
l
ow i
ng for som e ti
l
t, but M r. D atta’
s
design takes that idea further; the cooker can be tilted to maintain a nearly
90-degree angl
e to the l
i
ght as the sun’
s posi
ti
on i
n the sky changes. A l
ong
leg on one end of the cooker allows for sharp tilt, while four internal shelves
sw i
ng freel
y to keep up to four pots of food hori
zontalas the cooker’
s ti
l
t i
s
adjusted for changing sun angles. When the cooker is flat and the sun is
overhead, the sunlight will shine on the pot lids. When the cooker is tilted to
face a lower sun, much of
the sunlight will strike the
sides of the pots.
M r. D atta’
s desi
gn appeal
s to
me for several reasons:
 Keeping the window close
to perpendicular to the angle
of the sun’
s rays al
l
ow s the
cooker to work most
efficiently: few rays bounce
off the window. Also, little
sunlight hits the inside walls
of the cooker, making
internal reflective surfaces
unnecessary, thereby
offering potential savings in
production costs.
 Since the cooker is to be re-positioned about once per hour to track
the sun’
s m ovem ent, the spati
alrel
ati
onshi
p betw een refl
ectors and
cooker can be constant. Instead of reflectors that have to be adjusted
to many different positions, on this cooker there need be only two
positions: one for when the sun is striking the cooker at approximately
90 degrees, and one for when the cooker is being loaded, unloaded or
stored.
 Because it will still work when the sun is somewhat low in the sky, it
may allow users to solar cook more meals per year by taking better
advantage of marginal solar cooking conditions.
It is the last point that most interests me. If a new design feature adds 10 or
20 percent in production costs, but enables users to solar cook, say, 50

21. percent more meals per year, it may still be economical. This point further
highlights the need to match cooker designs with local climate conditions,
customs and usage.
M r. D atta’
s box cooker i
s m ade m ostl
y from al
u m i
num sheeti
ng, and
includes two panes of glass for the glazing. He estimates small-scale
production costs of the cooker, including labor, to be about $45. In India,
the cooker can boil four liters of water in less than two hours at midday.
On the downside, this new design needs repositioning hourly, whereas
simple solar box cookers can often be left unattended for three or more
hours. The new cooker al
so has a fai
rl
y sm al
l capaci
ty. It’
s d esi
gned to hol
d
four one-liter pots — perhaps ideal for smaller families, but limiting for
larger ones. Additionally, the cooker may be more susceptible to wind than
other models are. Others may want to tinker with this idea to see if the
increases in efficiency are worth additional effort in building and using the
"inclined box cooker."
Solar disinfection reducing water contamination for urban
poor
The Kenya Water for Health
Organization (KWAHO) reports that
20,000 families have benefited from an
ongoing SODIS project in the Kibera
slums of Nairobi, Kenya. SODIS — short
for "solar disinfection" — is a method of
inactivating microbes in contaminated
water by exposing transparent bottles
of water, placed horizontally on a flat
surface, to direct sunshine for at least
six hours. (On partly cloudy or overcast
days it is recommended that bottles be
exposed for two full days.)
"Through the combination of SODIS and proper hygiene practices," says
KWAHO, "user families have improved their drinking water quality. The
20,000 families mainly report health improvements and savings on
medication."

22. One Kibera resident, Laila, was initially skeptical of the idea. Says Laila, "I
was puzzled and surprised when I was approached by KWAHO, telling me
about the SODIS water treatment method. I did not believe that a clear
plastic bottle, when exposed to the sun, could treat the water properly. I
have been using SODIS consistently and I got a total of 10 bottles for
SODIS. I have gained a lot since I began using SODIS; I can now afford to
drink treated water consistentl
y w hi
ch I never used to. … The heal
th of m y
family has improved a great deal, as there is no case of diarrhea like before.
I am saving on medication and fuel."
With assistance from the Swiss Department of Water and Sanitation in
Developing Countries (SANDEC), KWAHO hopes to continue educating Kibera
residents about the SODIS method.

International board member, has studied solar water pasteurization
extensively and has experience with the SODIS procedure. He agrees that
SODIS can inactivate bateria on sunny days, but he points out that it has
some limitations. The SODIS method cannot be used for turbid water or for
milk, since turbidity and non-clear liquids tend to block the sunlight from
reaching and destroying all the bacteria. Also, tests have found that viruses
are more resistant to direct sunshine than are bacteria. Furthermore, the
SODIS method has no certain end-point, making it difficult to be certain that
all pathogens have been inactivated during partial sunshine or with
moderately turbid water. Dr. Metcalf says, "SODIS is a valuable first step in
reducing pathogens in water. Where water is heavily contaminated, adding
heat with simple solar cookers and water pasteurization indicators (WAPIs)
guarantees pathogen-free water.]
