Burkina Faso

Community members in Bobo Dioulasso formed the TLE NAFA association in 2004 to promote solar energy and reduce deforestation. In 2005, the association carried out two projects with 35 Papillon solar cookers: curved concentrators consisting of two reflective "wings" with a gap in between to allow for comfortable use by the cook, and folding reflectors for transport and storage. The cookers were made in Ouagadougou and assembled in Bobo Dioulasso. After a 20% subsidy, the cookers sold for about 120 euro each. Sales proceeds were used to buy additional supplies. TLE NAFA planned to sell at least 15 more in 2006. The group is currently seeking financial support. Contact: Monika Hermann-Sanou, Association TLE NAFA, B.P. 3440, Bobo Dioulasso, Burkina Faso.

KoZon Foundation began introducing solar CooKits in Gorom-Gorom, Oudalan in 1997. As is often the case, initial acceptance was very high. To measure long-term acceptance and usage, KoZon surveyed more than 50 families multiple times from 2002-2005. During the dry season, lasting from March-June, 30-45% of the families used their CooKits regularly (approximately 3-7 times per week). The month of April had highest usage, followed by May and March respectively. CooKits were used to cook a variety of foods, especially rice and sauces of meat, chicken or legumes. Nearly all families rated food taste as good to very good. CooKits were also used to heat milk for making yoghurt, and to heat water for making tea and coffee, as well as for washing purposes. Several families said that the capacity of one CooKit was not enough for large families, and that two CooKits would be better. Durability of the cooker was also mentioned as a concern, given that the cost of a CooKit and a pot is 5000 to 7500 CFA franc, or about $10 to $15. Even though this is quite expensive for the families of Gorom-Gorom, each solar-cooked meal saved an estimated 50-180 CFA franc in fuel costs. Over 90% of the families said they planned to buy a replacement CooKit when theirs wears out. KoZon lists several lessons learned during this process, including: 1) One CooKit is best suited for families of less than six members, or for single male households; 2) Complementary technologies, such as fuel-efficient wood stoves and heat-retention cookers, should continue to be taught in addition to solar cookers; and 3) Ongoing guidance, encouragement and follow-up should be provided by trained members of local institutions.

Sylvain Kimour Kalubi of the Terre de la Paix group has been busy translating solar cooker information on the Solar Cooking Archive into several local languages. Kalubi and his colleagues have also been experimenting with various cooker designs, including the 12-sided Parvati model, and have developed their own solar box cooker called the KIN 1. Kalubi has found advantages to using cassava (or manioc) flour instead of wheat flour for making paste. He says the cassava flour is cheaper in the Congo than wheat flour, and it makes a stronger glue for cardboard solar cookers.

Nahom Nigussie is fascinated by his solar box cooker.Nahom Nigussie of Eritrea writes that he made a solar box cooker based on the instructions sent to him by Solar Cookers International. "I cooked rice, sauce and shiro (traditional pea sauce) within two hours, and one hour for tea. I expect it will cook better in shorter time during summer. … It is fascinating to look at the food cooked by sun. The fascination of making and using solar cookers also lies in its freely available source of energy — the sun."


Representatives of Somalia-based Sun Fire Cooking attended January's World Social Forum in Nairobi, where they organized a group of activists to plan a three-part campaign of education, mobilization and networking for solar cooking. Sun Fire Cooking plans to open a solar cooking promotion center in Nairobi with support from Horn Relief, a nonprofit organization in Somalia. Meanwhile, Sun Fire Cooking continues its work spreading solar cooking in Puntland, Somalia, and plans to expand to the Hargeisa area. The organization also has experience in Djibouti, having sold 25 solar cookers there. Contact: Jim Lindsay, Sun Fire Cooking, 10680 Hampshire Ave S., Apt. 105, Bloomington, Minnesota 55438, USA.

Prototype of a solar cooker made from local materials in DarfurThe nonprofit Darfur Peace and Development Organization (DPADO) is incorporating solar cooking as part of its project to establish women's centers for displaced Darfurians in Sudan. The solar cooking component is coordinated by Stephen Harrigan, who has built and experimented with solar cookers and has demonstrated their use in Darfur. According to Harrigan, DPADO has "a large local Sudanese infrastructure already in place in Darfur to really promote this well" in camps for displaced people. He hopes to begin training in Khartoum this spring. Contact: Stephen Harrigan, Darfur Peace and Development Organization, c/o Suliman Giddo, P.O. Box 5743, Fort Wayne, Indiana 46895, USA.

The Web site of Solar Circle tells an inspiring story of how a few people can make a big difference by working together. Solar Circle is a US-based nonprofit organization made up of a network of friends, mostly women. A few years ago, Solar Circle took two dozen American-made Global Sun Ovens® to Masasi, Tanzania, where they were enthusiastically received. However, people quickly saw the impossibility of importing enough ovens to overcome high purchase and transport costs. Consequently, Solar Circle has started a small industry in Tanzania to build solar box cookers. Several Tanzanian craftspeople have joined in the effort. They make the outer box from cypress wood, which is treated with cashew nut oil to repel insects. Reflective surfaces are made by collecting and cleaning discarded lithographic plates, and crafting them into the proper shapes. Gaskets are made from used tires or shoe leather. Students from the Mechanical Engineering Design Program at Michigan State University (USA) are collaborating to develop a model that is lighter, cheaper and more efficient, using only domestic Tanzanian materials and manufacturing processes. Mlelwa, one Tanzanian who built a solar oven, coined a new proverb: "People say 'Jua kali,' but we know 'Jua ni mali .'" (People say the sun is hot today, but we know the hot sun is wealth).

Dozens of delegates from many parts of Togo and Ghana attended a conference last December in Lome themed "climate change: a socio-political challenge." The conference was organized by Jeunes Volontaires pour l'Environnement (JVE) and showcased solar cooking and solar water pasteurization. Demonstrations and construction workshops were available to conference attendees. Beneficiaries of a JVE solar project shared testimonials of how solar cooking has changed lives in the Vo region. Also attending the conference were Togo's Deputy Director of the Ministry of Environment, the Chief Cabinet to the Minister of Youth, and representatives of the media.

In the last six months of 2006, the Solar Connect Association (SCA) distributed 300 solar CooKits in rural areas of western Uganda, including the villages of Kikokwa and Ruharo, as well as in the Orukiga refugee settlement. With support from its new partner — the Foundation for Solar Cookers in the Netherlands — the SCA plans to disseminate an additional 2000 solar cookers in the western areas by the end of 2007. The SCA has worked with Project Environmentale de Virunga in the eastern Congo, near the habitat of the mountain gorillas, and with the Association Burundais pour la Protection des Oiseaux in Bunjumbura-Burundi. Both of these neighboring organizations reportedly need sources for low-cost aluminum foil and other materials. Contact: Solar Connect Association, P.O. Box 425, Kampala, Kyandodo 256, Uganda.

Solar cookers are parted of Integrated CookingLongtime solar cooking advocate and trainer Wilfred Pimentel, along with Ken Goyer and Cynthia Wee, led a two-day "integrated cooking" workshop in Pambak, Vanadzor, Armenia last August. They taught three technologies: solar cookers, fuel-efficient stoves and heat-retention cookers. With access to these complementary technologies, food can be cooked regardless of time of day and season, and with a maximum of overall fuel savings. The group demonstrated both panel-type and parabolic-type solar cookers, though the region's altitude and climate limit the amount of solar cooking that can be done with simple solar cookers. Seventeen people from a number of Armenian villages attended the workshop, held at the Peace Corps training center. Each participant received a CooKit and educational literature. They plan to return to their villages and begin teaching others about integrated cooking. Contact: Wilfred Pimentel, 1035 East Cambridge, Fresno, California 93704, USA.

Sankha Subhra Datta's suspended solar box cooker can be rotated on two axes for increased performance.Sankha Subhra Datta has designed a solar box cooker that is suspended at two points within a support frame, allowing for rotation of the entire cooker around a horizontal axis from 5 to 70 degrees with respect to the ground. The cooker can therefore maintain a nearly 90-degree angle to the light as the sun's position in the sky changes. The cooker is rotated around a horizontal axis by repositioning a bar that is attached to the lower front corners of the box between any of 14 slots spread across the base of the frame. Datta says this system has advantages over solar box cookers with tilt-adjusting rear legs — a greater range of rotation can be achieved, and the cook can rotate the unit smoothly without having to lift its entire weight and risk food spillage. Another design feature that helps to prevent food spills is the weighted, rotating cooking tray that keeps the pot horizontal at all times. Regardless of cooker rotation, the pot is always at the center of the cooker because the tray rotates on the horizontal axis of the pot. "This tray holding arrangement is designed for proper utilization of top and bottom reflectors at every inclination … which is not possible in simply suspended tray arrangements [because] shifting of pot location from the central position of the inner box due to the rotation of pot around pivots," Datta says. The cooker frame sits on casters for easy rotation around the vertical axis. The outer box is constructed of galvanized iron and the inner box is aluminum, with glass wool insulation in between. The glazing is double-paned glass with a two-centimeter air gap. Contact: Sankha Subhra Datta, Mohanta Para, PO & DIST.- Jalpaiguri, West Bengal - 735 101, India. E-mail: or

Fair Fabricators has been honored for its "outstanding performance" in India's solar cooker program. The award was sponsored by the governmental Ministry of Non-conventional Energy Sources (MNES). Fair Fabricators reports that it has manufactured and sold more than 100,000 solar cookers in the last two decades. The company is a leading manufacturer of aluminum-bodied solar box cookers, but also manufactures parabolic-type solar cookers and expects to begin production of solar box cookers made of fiber-reinforced polymer (FRP).

The government of Nepal has adopted a rural energy policy aimed at reducing rural poverty and protecting the environment. The government hopes to encourage local organizations, nongovernmental organizations and cooperatives to develop a variety of new energy sources such as micro-hydro, wind and solar. According to solar cooking promoter Sanu Kaji Shrestha, the government has recently increased its subsidy for some parabolic-type solar cookers to 4000 rupees per unit, while there also is a 50% subsidy on some solar box cookers. However, he says it is difficult to fulfill the government's criteria for receiving subsidies. He estimates there are about 2500 solar cookers distributed in rural communities so far.

El Sudcaliforniano newspaper of La Paz, Mexico recently reported on a small solar cooking project started by Mercedes Gorrete Solis Lucero, a local biochemical engineer. Thus far, 20 demonstration solar cookers have been constructed — eight parabolic-type, six box-type and six panel-type. The purpose of the project is to make solar thermal technology available to the community at low cost while contributing to an ecological culture. The state of Baja California Sur enjoys more than 260 sunny days per year, suffers from scarcity of firewood and is home to people who tend to put new technologies into practice, the newspaper says. Gorrete Solis Lucero demonstrates the cookers at events such as the state government's women's exposition She says most people become interested, show enthusiasm and ask questions, and she has a special method for dealing with doubts. "I make pastries," she says.


In February, Paraguay became the first country in Latin America to offer a master's degree in Sustainable Development, Renewable Energy and Energy Efficiency. Paraguay is following the lead of Spain, which has offered such a degree for five years. The degree is offered in response to global climate change and strains on global energy supplies. The 18-month course will cover themes such as sustainable development; energy management and efficiency; solar, wind and hydro energy applications; bio-fuels; project evaluation techniques; and economic management. The course contains both on-line and traditional classroom components. The course was organized by the UNESCO professorship in sustainability of the Universitat Politècnica de Catalunya, the Universidad Nacional de Asunción (UNA), and several other universities in Spain, Paraguay, Nicaragua and Argentina. It is sponsored by the European Union's Urb-Al program, which links interested urban and rural organizations from various European and Latin American countries in decentralized cooperation networks.

Conference participants demonstrated several types of solar cookers to the general public.The third national solar energy conference was held in February in the city of Guichon, Paysandú. Sponsored by the Uruguayan Center of Appropriate Technologies (CEUTA), delegates attended from all departments in the country. Also attending were representatives of the National Bureau for the Environment (DINAMA), U.N. Educational, Scientific and Cultural Organization (UNESCO), and the municipal government of Paysandú. Solar cookers were on display in Plaza Williman, where they could be seen by the general public. The city of Guichon was the site of a workshop on construction and use of solar cookers in 2004. Out of that gathering has grown the national solar conferences. The fourth national conference will be held early in 2008.

The Kyoto Twist Solar Cooking Society (KTSCS) continues its efforts to raise funds for solar cooking projects that reduce poverty in sun-rich, fuel-poor countries while reducing greenhouse gas emissions. (The "twist" part of the name comes from the idea that those living in wealthier nations can change, or twist, their priorities and lifestyles to better share limited resources with those most in need.) KTSCS works with nongovernmental organizations (NGOs) that have solar cooker experience and a proven track record in countries where solar cookers are an appropriate technology. NGOs can request an application packet for consideration of funding. Project structure, recipient family selection parameters, training procedures, and follow-up services must be described in detail. To monitor the effectiveness of the projects, and to provide accountability to its donors, KTSCS will track the success of recipient families, their financial savings due to solar cooker use, and their greenhouse gas emission reductions. KTSCS funded its first pilot project in November 2005. The group that received funding — Ananda Marga Universal Relief Team (AMURT) — has worked in Haiti for over 15 years and has experience conducting solar cooker projects. "The Spirit of the Kyoto [Protocol] is international cooperation on what is now being called the biggest challenge mankind has ever faced — massive and rapid climate change," states the KTSCS Web site. "At an average cost of ten dollars per tonne, donating to KTSCS is an effective way to help make a difference. Cooking fires in the world today consume an estimated one billion cubic meters of wood or biomass annually, which produces an estimated one billion tonnes of carbon dioxide. Those are easy figures to remember and very significant in the mitigation of global warming." Contact: Jack Anderson, The Kyoto Twist, Box 191, Lund, British Columbia V0N-2G0, Canada. E-mail:, Web:


"Bon Appétit Monsieur Soleil," a film about solar cooking in Burkina Faso, earned top honors and a 5000 euro prize at the International Ecological Film Festival in Bourges, France this past October. The film was directed by Boris Claret and produced by Association La Trame documentary film studio. The festival program described the film as follows: "At the edge of the Sahel, firewood is rare and expensive. To counter deforestation, a whole network of nongovernmental organizations, craftsmen welders, and women's associations have developed for 10 years an effective alternative: parabolic solar cookers."

A photovoltaic cell, seen here at the top edge of the Pil Kaar 2, powers a microcomputer that adjusts the two reflectorsThe Mueller Solartechnik company will soon release its latest solar box cooker, Zèbre. It has two opposing reflectors that automatically adjust throughout the day to track the movement of the sun, using a microcomputer powered by photovoltaic cells. This allows for constant temperatures to be maintained over extended periods of time without manual adjustment. Due to the design of the cooker and placement of the reflectors, it is recommended primarily for those in equatorial regions. Contact: Mueller Solartechnik, Obergasse 33, 55234 Offenheim, Germany.

A baby carriage keeps the SunStar out of the snow and angled towards the sunA couple of years ago, Brit Bakken Oedegaard happened upon the Solar Cooking Archive while researching garden plants on the Internet. She had some free time, and decided to build a couple of the solar cookers from plans on the site. She built a solar CooKit and a Reflective Open Box (ROB) cooker. Living in Norway, at 57 degrees north of the equator, Oedegaard didn't expect that she'd be able to do any real solar cooking, but she thought it would be a fun experiment. This makeshift solar cooker boils water in less than 15 minutesThe ROB brought water to a boil and the CooKit heated water to 91°C. These achievements were made in late February, with snow on the ground and an ambient temperature slightly above freezing. Encouraged by the results, she built other cookers, including a SunStar and a 12-sided Parvati. Oedegaard and her husband used tables, metal stands, and even a baby carriage to hold the cookers above the snow and to angle the cookers toward the low winter sun. Using a homemade stand and a discarded satellite television dish, Oedegaard constructed a parabolic-type solar cooker that boiled a liter of water in 14 minutes — in late October, when the sun was low and the ambient temperature only 7°C. "I think this certainly proves that solar cooking is not only for hot climates," Oedegaard writes, "and I hope people who live in Canada, Northern Europe and Northern Asia will learn to use the energy from the sun in more ways than we thought possible earlier."


Former SCI Executive Director Bev Blum demonstrated solar cookers and built solar CooKits at a conference titled "Killer in the Kitchen: Indoor Air Pollution and Appropriate Technology Solutions" held last November in Alabama. The purpose of the conference was two-fold: to spotlight the global problem of indoor air pollution related to smoky cooking fires, and to explore proven appropriate technology solutions. Several technologies were presented, including fuel-efficient "rocket" stoves, heat-retention cookers, and solar cookers. Solar Oven Society's Martha Port provided additional information on solar cooking and solar water pasteurization. "There was a strong consensus that the ideal way to address smoke hazards is integrated introduction of fuel-efficient stoves, solar cookers and heat-retention cookers," Blum writes. "It was a great experience." The conference was sponsored by Servants in Faith and Technology (SIFAT), the Sparkman Center for Global Health, and the University of Alabama at Birmingham Framework Program. SIFAT offers courses on a range of topics — including appropriate technology, international health, and microenterprise development — from a Christian perspective.

ClearDome Solar Thermal is adding a new product to its line of solar cookers: the SolaReflex Pyramid. As its name implies, the cooker is shaped like a pyramid. It consists of a base, three sides, and an adjustable front reflector. The removable, washable base is made of a non-toxic, heat-absorbing black plastic. Two of the three polycarbonate sides are lined with ClearDome's highly-reflective SolaReflex foil, while the third side is transparent. The cooker's designer, Deris Jeannette, calls the cooker "an enclosed panel-type solar cooker." Like most panel-type cookers, the SolaReflex Pyramid does not have to be rotated frequently since it accepts sunlight from a wide range of angles. Unlike most panel-type cookers, however, it is fully enclosed and therefore does not require the use of a transparent cooking bag. The SolaReflex Pyramid comes in two sizes: a one-liter model that stands 30 centimeters tall, and a four-liter model that stands 45 centimeters tall. Both are available in collapsible and non-collapsible forms. Larger models may be available in the future.

Darfur refugees keep on cookin'

By Derk Rijks, project leader

After foil is adhered, the cardboard sheets are carefully placed in racks to dry before being cut and foldedIn Iridimi refugee camp in Chad about 17000 refugees from Darfur, Sudan have found temporary shelter. This camp is situated in a semi desert region at 15° N, where rainfall is irregular and usually less than 120 millimeters per year. As a result, the land is seasonally and sparsely covered with grasses. Shrubs and trees only grow on the edges of wadis — dry riverbeds that carry water a few days a year.

While firewood for cooking was sufficient for the few small, dispersed villages located along the wadis, it was not nearly enough for a sudden influx of thousands of refugees. After Iridimi camp was established, the U.N. High Commissioner for Refugees (UNHCR) imported a limited supply of firewood, so women roamed the countryside for more. Indigenous villagers saw this as a threat to their own supply. With more than 330 sunny days each year in the camp, it seemed to me that solar cookers could provide some relief.

We decided to use solar CooKits due to their ease of use and potential for local manufacture and maintenance by refugees. After conducting a series of well-received demonstrations, we formulated a project outline and sought funding for materials and remuneration of trainers and refugee helpers. Chadian citizens Marie-Rose Neloum and Gilhoube Patallet led trainings, managed supplies and funds, and provided general support.

Derk Rijks (right) is congratulated by Don Cheadle.After a short period of hesitation, the Iridimi women were convinced that the sun could cook. They embraced solar cooking wholeheartedly. Even most men are now happy with the new techniques, though the final decision clearly rests with the women! Virtually all of their traditional meals can be made with solar cookers.

During normal security conditions about 1000 CooKits are produced each month by a rotation of 20 "artisans," two from each camp zone. A workshop was built for this purpose. Forty refugee women are trained as auxiliary trainers, and in groups of two they teach six women each week how to solar cook. There are more than 4500 women in the camp, of which over 2500 have received training. Once trained, the women each receive two to three CooKits and pots, depending on family size.

The project has suffered twice from a slow-down in activity because of security concerns. The daily meal strategy adopted by UNHCR is as follows: breakfast, cooked on improved woodstoves with UNHCR-distributed firewood; lunch, cooked in solar cookers; and dinner, cooked in solar cookers and/or heat-retention cookers (also known as "hay baskets," these are insulated enclosures in which is set a pot of food that has been brought to a boil, allowing it to continue to cook after being removed from its heat source.) The heat-retention cookers are woven by the refugee women, using materials that are brought in from other parts of the country.

Refugee-defined benefits from solar cooking include:

  • "We keep clean, do not have tears in our eyes and have no running noses from smoke"
  • "We do not have to go and look for firewood in far away places where we do not want to go (for safety reasons)"
  • "There is no fire danger for our children or our tents"
  • "We can use the saved firewood collection time to do handiwork (for sale and buying extra food or milk), to be with our children, or to learn from the classes taught in the camp"

At one point, in our absence, an independent subcontractor with UNHCR decided arbitrarily and without consultation to halt solar cooking trainings because the majority of the older women had been trained. There was a camp-wide protest that was immediately resolved upon our return. Now, training is guaranteed for those 15 years and older, though we do not check ages and are happy to train younger girls pretending to be 15! Women in many other regional refugee camps have expressed great interest in having their own solar cooking projects, and
UNHCR has given its support to the idea.

Editor's note: Last month, Rijks, Neloum and Patallet received the 2007 Prize for Humanity, presented by the Immortal Chaplains Foundation. The award honors those who "risked all to protect others of a different faith or ethnic origin." The award was presented in Long Beach, California (USA) by Oscar-nominated actor Don Cheadle, known for his activism on behalf of the victims of the Darfur crisis.

Message from the Executive Director

By Patrick Widner, SCI executive director

SCI Executive Director Patrick Widner (left) and Derk RijksRecently I attended a workshop that included a discussion about another Superpower on earth, this one made up of
nongovernmental organizations, community-based organizations and individuals that focus on equality for humanity, social
justice and the environment. Another way of looking at this positive force is as an immune system for what ails the planet.

This Superpower concept manifested itself at an event honoring Derk Rijks, Marie-Rose Neloum, and Gilhoube Patallet. (See
"Darfur refugees keep on cookin'.") All of them were recognized by the Immortal Chaplains Foundation as recipients of the
2007 Prize for Humanity for their work in the Iridimi refugee camp in Chad. Paul and Tatiana Rusesabagina of "Hotel Rwanda"
fame were present, and Desmond Tutu and Jane Goodall sent special taped messages for the event.

Derk Rijks, representative of the Netherlands-based nonprofit KoZon Foundation and an associate of Solar Cookers
International (SCI) and Jewish World Watch, introduced the CooKit to Darfur refugees at Iridimi camp in 2005. Rijks will now expand this work into other camps. His involvement, and that of his African colleagues who were honored, have made a safer life for so many families. I felt honored and humbled to be in the presence of these courageous people.

In reflecting on the above, the symbolism of an Afghan proverb sent by Patricia McArdle — qatra qatra daryaa mesha / drop by drop it becomes a river — is most appropriate when thinking about SCI. We have six volunteers at the office today adding their drops. Three of the volunteers are students packing CooKits and WAPIs and one is a teacher who taught her students to make solar cookers. At the same time, volunteer SCI advocates in New York, Washington, D.C., and Geneva are preparing for the upcoming fourth session of the Human Rights Council at the United Nations. Countless others throughout the world are promoting the use of the sun's energy through teaching and demonstrations of simple technologies for solar cooking and water pasteurization.

Thanks to all of you who have added to the river. Let it rain! Except, when we are solar cooking.

SCI Association: ready to be heard

Compiled by Bev Blum, SCIA secretariat

Advocacy group leader Sonia Heptonstall, a solar cooking representative at the UN in Geneva, shares her knowledge with other promoters.The Solar Cookers International Association (SCIA), an umbrella organization of Solar Cookers International (SCI), has grown rapidly since its formation at the 2006 international solar cookers conference last July. SCIA members are now ready to speak with a strong, unified voice on behalf of wider access to solar cooking, solar pasteurizing and solar food processing. Wider access will be accomplished through more partnerships with U.N. agencies, international development and relief organizations, policy makers, businesses, and networks related to women, health and energy.

Ninety-nine individuals and 56 organizations from 32 countries joined the SCIA during 2006, making them founding members. A 17-member steering committee elected David Whitfield, of the Center for Development of Solar Energy (CEDESOL) in Cochabamba, Bolivia, as its chairperson.

Steering committee chairperson David Whitfield (center) discusses goals and strategies with members of the Latin America and Iberia network.While acknowledging that SCIA members have diverse opinions on specific strategies, programs and devices, the steering committee identified a number of statements that are agreed upon:

  • In sun-rich areas, solar cookers are improving people's health, economics and environments
  • Solar cookers are urgently needed by people in fuel-scarce, sun-rich areas
  • Solar cookers complement, but don't replace other cooking methods
  • Virtually all foods can be cooked equally or better in one or more types of solar cookers
  • Solar cookers are clean and pollution-free; most are also safer than fire, and save time and money
  • Solar cookers provide a number of documented benefits for cooking, pasteurizing and food processing across the globe
SCIA members can readily share information and ideas on the Internet using Solar Cookers International Discussion Forums ( A number of regional and topical forums are available. Participation is not limited to SCIA members.

A variety of foods can be processed and conserved with simple solar technologies, including these dried fruits and vegetables displayed by the Solar Food Processing and Conservation group.The Advocacy group, headed by Dr. Sonia Heptonstall of Geneva, has increased communication among top solar cooker advocates in Geneva, New York and Washington, D.C. Group members contributed to meetings of the U.N. Commission on Sustainable Development in New York, and will attend World Health Organization (WHO) meetings in Geneva.

The Solar Food Processing and Conservation group, coordinated by Rolf Behringer of the International Solar Energy Society (ISES), has produced an interesting general information brochure with real-world examples. The brochure is available on-line
at in English, Chinese, French, Spanish and German languages. If you have an income-generating solar food project please consider submitting its details on the same Web site.

Education group member Rowena Gerber will be presenting at the 2nd annual Celebration of Teaching and Learning in New York City on 22-23 March. Dubbed the "World's Fair for educators," this year's event will focus on science and global awareness.

Sun Ovens International's Paul Munsen will join Gerber, as will several of her students. Gerber will demonstrate, in her words, "just about every type of solar oven ever made." Former U.S. Vice President Al Gore will also be speaking at the event.

Observable solar cooking communities

Association member (and new SCI board member) Patricia McArdle put out a call for communities worldwide that have 100+ solar cooking families clustered enough that it would be reasonable for them to receive visitors. Thus far, 25 communities in eight countries have been identified. (The two Afghanistan communities have less than 100 families.) Note that five of eight countries are in Asia, where fuel scarcities appeared earliest. For more information, or to add a community, send an e-mail to Bev Blum:

My solar cooker epiphany

by Patricia McArdle, SCI board of directors

Patricia McArdle at the 2006 international solar cookers conferenceIn 2005 I served as the U.S. government representative at a British Army-run Provincial Reconstruction Team in Northern Afghanistan. I had heard of solar cookers before I went to Afghanistan, but I knew little about them or their incredible potential to save forests, reduce pollution and improve the lives of millions of women.

My solar cooker epiphany occurred on a cold but sunny March day while on patrol in the Hindu Kush with one of our military observation teams. During my travels around northern Afghanistan, I had observed that there were almost no trees and little groundcover left in the region. People told me that the trees had been cut down for firewood or to make charcoal. As we drove that morning up a narrow mountain trail to a remote village for a meeting with local officials, we passed a group of young (five-seven year old) children leading donkeys down the trail.

After our meeting, the soldiers and I were given a tour of the village. The district governor showed us the one remaining “forest” in the area, a small grove of cedar and pine growing just above the village. It was guarded night and day to prevent the trees from being cut down for firewood. The governor explained to us that if they lost their “forest,” the next big rain would wash away the village. I was also invited into one of the family compounds and introduced to the women who were cooking lunch over a smoky fire fueled with what looked like tumbleweed stacked in a huge pile next to their mud-walled hut.

At the end of the day, heading down the mountain, we again passed the children, who were on their way home. Their donkeys were barely visible under enormous bundles of the same “tumbleweed” I had seen the women cooking with. As we traveled west into the glare of the setting sun, I thought to myself, “Someone should tell these people about solar cookers.” Since I didn’t know much about solar cookers myself, I did some research.

That night, back at our camp in Mazar-e Sharif, I trolled the Internet for information on solar cookers and was astounded at the number of Web sites I found. I spent the next few evenings learning about this remarkably simple technology. Eventually I downloaded several plans, and asked the British Army kitchen staff for some old cardboard boxes, aluminum foil and flour to make paste. With the help of the soldiers, I constructed five different box- and panel-type solar cookers. We took them up to the roof of our heavily guarded compound and, over a period of several weeks, tested them and measured the results. The solar “CooKit” won the competition.

It was clear to me that there was a great potential in this country for the widespread distribution of solar cookers to:

  • Reduce the amount of time children spend foraging for fuel
  • Reduce erosion caused by a lack of ground cover (and the resulting flooding)
  • Cut down on the amount of smoke that women are exposed to while cooking

I hoped to return eventually to the village that had inspired me to learn about solar cookers, to demonstrate the CooKit and see how the people would react to this remarkable technology. Four months later, we went back.
It was another cool, sunny day. A small group of men standing in front of the governor’s house watched in silence as we arrived for our meeting. (Women are not allowed out in public unless the gathering is all female). Before going in to see the governor, I poured a bottle of water into a black pot, put the pot inside a transparent oven bag, placed the bag in my homemade CooKit, turned the CooKit to face the sun and went inside with the soldiers.

When we came out of the meeting 90 minutes later, the pot was steaming and the crowd had swelled from 10 to about 40 men. They were scratching their beards, pointing at the CooKit and trying to figure out how this piece of cardboard covered with shiny paper was able to boil water. Where was the fire? It looked to them like magic even after I explained how it worked. The pot was clearly very hot, but the cardboard and aluminum foil were not. How could this be? They all insisted on coming up to touch the very hot pot and then the cool foil-covered cardboard to confirm what they were seeing.

One of the men exclaimed, “We could make our tea with this!” The others nodded enthusiastically. Another said he would be able to find cardboard, but “where,” he asked, “do I get that shiny paper?” They all looked at me in silence, waiting for an answer. I wasn’t certain how to reply, because I knew that aluminum foil was not sold anywhere but Kabul, which was more than 100 miles to the south over the Hindu Kush.

Another man smiled, reached into his back pocket and took out a pack of cigarettes. He pulled up the inner foil liner and shouted, “We could use this!” The other men nodded, and several more pulled out their own cigarette packs to examine the foil liners. Within five minutes, these men had figured out a use for this technology and they had discovered a way to manufacture it using a locally available resource. None of them suggested that their wives might be able to cook meals with this technology, but I was still very impressed with their positive and creative reaction to my very brief demonstration. If they only used the CooKit for heating tea water, they would still dramatically reduce the biomass consumption of their village.

I began inquiring about solar cooker projects in Afghanistan and found that only Gordon Magney, who has distributed several hundred “SOS Sport” solar box cookers , was currently involved with solar cookers there. (I learned later that Sun Ovens International had, several years earlier, distributed solar cookers in Afghanistan.) Magney gave me a detailed proposal for another solar cooker project. I tried to generate support for his project within our embassy and U.S. Agency for International Development (USAID) mission, but, sadly, was not successful.

I have told this story and given solar cooker presentations many times at the U.S. State Department, the Peace Corps, USAID and elsewhere since my return from Afghanistan. Currently the U.S. government is partially funding only one solar cooker project, with Solar Household Energy (SHE) in Mexico. I plan to continue working to convince my colleagues in the government to support the spread of solar cooker technology around the world.

Show your support with a stamp

The Paraguay postage stamp features a parabolic-type solar cooker Martin Almada reports that Paraguay has issued a postage stamp featuring a solar cooker. He feels the stamp is an advance in spreading awareness of solar cookers, and will contribute to environmental protection and energy conservation. He hopes that organizations elsewhere will follow this example and encourage creation of solar postage stamps in their own countries.
The Tanzania postage stamp features a panel-type solar cooker. In 2004, Tanzania Posts Corporation released a series of postage stamps commemorating the 75th anniversary of Girl Guiding in Tanzania. Included in the set was a stamp depicting Girl Guides “demonstrating environment friendly solar cookers.”

Another world is possible … with solar cooking!

by Margaret Owino, SCI eastern Africa director

Another world is possible! This was the message at the 2007 World Social Forum held in Nairobi on 20-26 January, 2007. This short, clear message was there for world movers to see, hear and deliberate on. People from all over the world came, bearing one message or another, and Solar Cookers International (SCI) was there, too.

SCI's Faustine Odaba explains solar cooking to a group of dancers.The Forum was filled with speeches, discussions, exhibits, dances and music. SCI displayed three major types of solar cookers: concentrator cookers, box cookers and panel cookers, including SCI's CooKit. The cookers were used over four days to demonstrate that another world is possible by using the sun's energy to fulfill a basic need — the need for clean, free energy to cook food and pasteurize drinking water.
Many exhibitors had products to sell, but SCI was there to talk about solar cooking, to show people what solar cookers are and how they work, and to share with them the flavorful, nutritious rewards of a solar-cooked dish. All doubts were swept away as people sampled roasted peanuts, doughnuts, cakes, roast meat and local Kenyan dishes such as Ugali and Githeri.

Flanked by our Swiss friends Roland and Monica Baumann and Schmid Bonhard, who brought a beautiful solar box cooker with them, and supported by Pax Romana, a church group that let us use their stand, we made good use of the opportunity. Forum participants went away with new solar cooking knowledge, new memories in their cameras, and sometimes even new CooKits. They also went away convinced that another world is possible … with solar cooking.

California High School raises money for Darfur refugees

Solar Cookers International (SCI) received this kind letter from a local high school student, along with a donation in support of solar cooking. SCI would like to express its gratitude for the initiative taken by these young adults:

Members of Mira Loma High School's Solar Cooking Club raised runds through a variety of activities, including trick-or-treating. One of them is actually wearing a solar cooker!Enclosed is a donation from the members of Mira Loma High School’s new Solar Cooking Club. This year, we have been working to spread solar cooking in our school community as well as raising money for Solar Cookers International’s Darfur relief effort. We have had several fundraisers so far. In September, we sold solar-cooked chili dogs at school. We also had a booth at the Salmon Festival, and on Halloween we went trick-or-treating for donations of spare change and handed out flyers on solar cooking. We intend to do more fundraising in the spring.

The members of the Solar Cooking Club are eager to help SCI in other ways too, so please contact us about any volunteer activities that are suitable for a group of high school students. On behalf of all members, I would like to offer my support for SCI's mission of spreading solar cooking in our community and around the world.
