Improving Health with Improved Cooking Stoves

Improving biomass cooking stoves is a powerful positive health intervention, especially in households that include children. Enclosing stoves prevents skirt fires, and burns that can be deadly or permanently disfiguring. Reducing emissions in cooking stoves, keeps those particles from building up in the lungs of babies, children and other family members, and improves survival rates from pneumonia, influenza, and other infections.

One of the ovens in use.

Eco-Kalan has adapted their Binkga Oven (named ofter the rice cakes that the ovens make) to use both locally available coconut charcoal and stick wood fuel.

The system uses the same oven bottom, and two different covers, one for wood and one for charcoal. Both ovens can bake high quality Bingka rice cakes, but with two different levels of particulate emissions. (Notice the soot on the wood fired oven). However, both ovens are cleaner than the hornohan stove that Eco-Kalan would like to replace.

The Bingka Oven works over a range of cooking temperatures (325 deg. F - 500 deg F) and has can cook both bingka and torta breads (with or without filling). Rebecca is anticipating that it will also work for a wide variety of other baked goods.

They have demonstrated the oven for local parents, teachers, government officials, and others. They have also reached out to people who work with remote communities that in the mountains. The first commercial production will target bakers who are preparing the bingka and torta on the more common and smokey hornohan stoves and anticipate the newer stove will give these bakers the ability to make high quality goods with lower costs and improved health.

Paul Anderson, Centre for Research in Energy and Energy Conservation (CREEC)

The Centre for Research in Energy and Energy Conservation (CREEC) is a not-for-profit organization which works “to enhance access to modern types of energy through research, training and consultancy”.

The CREEC offers independent stove testing services, and has recently tested the Quad 2 Stove.

For the full test report and method see the pdf:
http://www.stoves.bioenergylists.org/files/quad_2_stove.pdf

The center tested the Quad 2 Stove and found that:
The Quad stove boils 5L of water in 27 minutes. To boil and simmer 5L of water, it uses 636g of dry wood and has an energy use of 11713kJ. It has a thermal efficiency of 42% during the high power phase and 41% during simmering. It has a turndown ratio of 1.4, an indication that the stove’s firepower can be controlled for different cooking regimes. Its fuel use is considered to achieve significant, measurabe health and environmental goals according to the Lima Consensus Tiers of stove ranking.

With regards to safety, the stove scored 77.5% and is rated GOOD and is considered a Substantial Improvement according to the Lima Consensus Tiers of stove ranking.

I want to share with you some data abaut solar cookers in europe!
Information from: Solar cooking Atlas (www.solarcookingatlas.com) and ID Cook (www.Idcool.us)

**What is a solar cooker?**

It is not so complicated, a solar cooker, or solar oven is a box which uses the energy of sunlight to cook meal or sterilize.

The Low Smoke Chulha has been enabled by Philips Design in close co-operation with NGOs, self-help groups, local entrepreneurs and potential users. Low Smoke Chulha provides a safer home environment for families, reduces the risk of respiratory illness, and supports indigenous ways of cooking. The Low Smoke Chulha is not only smokeless but also helps every household save 10 kilos of firewood each house each day which is 4 tones of firewood a year!

See our page: http://www.lowsmokechulha.com/

The "Easy 5 Gallon Bucket Rocket Stove", is very easy to build. All materials anyone needs to cook a good hot meal is a metal 5 gallon bucket, some stove pipe and vermiculite, pearlite or similar insulation (even "wood ash" can be used). Since the insulation separates the heat from the housing, almost ALL of the flame and heat is directed up to the cooking pot or utensil. Almost NO heat is wasted, making it one of the most efficient rocket stoves I've seen. Definitely one one the EASIEST to build and transport!

Una reciente evaluación realizada por los refugiados de la Mujer de la Comisión en Haití constató que el precio del carbón ha aumentado en un 40% (CMR y el PMA 2010). Cómo ayudar a las poblaciones sujetas a desarrollar la capacidad de producción de biocombustibles líquidos puede ofrecer una importante solución a la pobreza energética en las comunidades desplazadas de Haití y contribuir a su desarrollo a largo plazo de la autosuficiencia energética.

Proyecto Gaia ha estado trabajando en Haití para promover el etanol y la Estufa CleanCook - una estufa a base de alcohol - como alternativa a las estufas que queman biomasa sólida (es decir, madera, carbón vegetal y briquetas.) El etanol es tan limpia como gas licuado de petróleo, más barata que el carbón, más seguro que el queroseno y tiene más potencial que las briquetas de basura. En África, el Proyecto Gaia ha acumulado más de 2 millones de días de cocinar con la estufa CleanCook sin un solo accidente de cierta importancia.

La pregunta más común que aparezcan durante nuestras conversaciones con los responsables políticos y los empresarios sociales es: ** "¿El suministro de etanol, sea sostenible? Y ¿dónde estaría la oferta provienen de donaciones después tocaban a su fin? "**

Esta es la pregunta clave de la sostenibilidad y la razón de por qué estamos tan interesados en Haití. No sólo fue Haití una vez al líder productor de azúcar y una destilería de etanol de bebidas para la exportación, así como el mercado local, pero también Haití existe en las rutas comerciales durante el cual miles de millones de litros de etanol cada año el flujo de camino a un mercado de combustibles en el los Estados Unidos. Este etanol, sobre todo de Brasil, generalmente el precio más competitivo en el mercado de materias primas, proporcionará una fuente de combustible para Haití-más barato que el petróleo-como Haití acumula su propia producción local (Etiopía Petróleo de datos empresariales). De hecho, el Gobierno brasileño se ha comprometido a donar más de 100.000 litros y un litros otros 400.000 en los próximos dos años.

A recent assessment conducted by the Women’s Refugee Commission in Haiti found that the price of charcoal has risen by 40% (WRC and WFP 2010). Helping subject populations to develop the capacity to produce liquid biofuels may offer one important solution to energy poverty in Haiti’s displaced communities and contribute to its long term development of energy self-sufficiency.

Clean Cook StoveClean Cook Stove

Project Gaia has been working in Haiti to promote ethanol and the CleanCook Stove - an alcohol based stove - as an alternative to stoves that burn solid biomass (i.e. wood, charcoal, and briquettes.) Ethanol is as clean as LPG, cheaper than charcoal, safer than kerosene and has greater potential than trash briquettes. In Africa, Project Gaia has accumulated over 2 million days of cooking with the CleanCook Stove without a single accident of any significance.

The most common question which arises during our discussions with policy makers and social entrepreneurs is:** “Would the supply of ethanol be sustainable? And where would the supply come from after donations were at an end?” **

This is the key sustainability question and the reason why we are so interested in Haiti. Not only was Haiti once a leading sugar producer and a distiller of beverage ethanol for export as well as the local market, but also Haiti exists on trade routes over which billions of liters of ethanol flow each year on their way to a fuel market in the United States. This ethanol, mostly from Brazil, generally the most competitively priced in the commodity market, will provide a source of fuel for Haiti—cheaper than kerosene—as Haiti builds up its own local production (Ethiopian Petroleum Enterprise Data). In fact, the Brazilian Government has pledged to donate over 100,000 liters and an additional 400,000 liters over the next two years.

Haiti was once a powerful agricultural economy, producing for its own needs. In 1983 Haiti harvested 70,000 hectares of sugarcane. Today it harvests less than 17,000 hectares (Figure 1: Decline in Sugar Cane Production (UN Data World Statistics Pocketbook)). Haiti’s dependence on export markets has increased its vulnerability through its reliance on basic sustenance items it once produced locally. Today it supplements most of its own food staples with imports – a precarious equilibrium. Other than charcoal, most other fuels are imported.

In regards to domestic ethanol production, Haitians are no strangers to the distillation of alcohol. Thousands of small mills and distilleries make beverage-grade ethanol in Haiti. In Léogâne alone, over 200 small distilleries were in operation before the earthquake (ESMAP 2007). Many of the existing distilleries in Haiti, those shut down or still in operation, could be repaired and refurbished to produce fuel grade ethanol. Project Gaia has been in contact with an operating distillery in the vicinity of Léogâne that could upgrade to produce hydrous ethanol fuel and put this fuel into the market in a matter of months.

Many opportunities exist for small scale distilleries. In Haiti, some small ethanol enterprises are already active thus presenting the perfect opportunity for value chain development through the support of SMEs (small and medium enterprises). The number of sugarcane transformation workshops throughout the country is an estimated 5,612 (ESMAP 2007)

Haitians rightly believe that Haiti’s way back from dependency is through agriculture and a renewed attention to domestic needs and markets. Therefore, by developing ethanol as a household fuel, it will profoundly benefit Haiti because Haitians can produce biofuels from their own agricultural crops. Moreover, Haitian families will finally have access to cooking fuel that is safe, clean, affordable and sustainable. A way back to economic - and human - health for Haiti is to produce ethanol for its domestic energy market.

It was not quite 9 months ago, when I sent out an email to a small group of collaborators, with a Subject line that asked the question: "How do we get biochar stoves to Central America?" Of course, like the punch line to the old vaudeville joke, the answer is "lots of hard work". I could not have imagined 9 months ago was how rewarding all that work would feel. I want to share that feeling with all of you.

I recently returned to Seattle from Costa Rica's famed coffee producing area the Santos Zone. This was my second trip since mid- January. I have been continuing my work as a technical consultant to a clean stove/biochar project. Proyecto Estufa Finca (Farm Stove) was initiated by organic coffee farmer Arturo Segura http://www.solcolibri.com/ and the members of the local citizens group APORTES.
