After over 30 years of doing theoretical and experimental research, the authors of this document (Newtech Co., Ltd. in Quy Nhon city, Binh Dinh and Tan My Kim Co., Ltd. in Ho Chi Minh city, Vietnam), until now, have completed all not only modern but also cheap & user-friendly technology solutions which can help the poor all over the world do cooking by gas generated at their home without buying any drops of liquefied gas.

These technologies solutions can be developed in a country or in a big city or small town in any countries in the world, even it is in America, Europe, Australia and especially in Asia and Africa.

The authors believe that the modern but simple technology solutions stated hereby will start an era of a great revolution in cooking for billions of the poor all over the world and they hope that such technology will satisfy all poor persons.

The authors are very willingly to transfer these technologies to the countries in accordance with the international law in order to be together with such countries to help the poor all over the world.

Great half hour television program explaining Rice Hull Gasifier Stoves, and their potential in Vietnam.

It includes a good comparison of different stove types and designs, and interviews with people using the stoves.

Quad 2 Stove

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.

Christa Roth's excellent report
Micro-gasification: Cooking with gas from dry biomass

has a new location:
https://energypedia.info/wiki/File:Micro_Gasification_Cooking_with_gas_f...

Her comprehensive survey of micro-gasification technology has great technical information and is well worth the read.

thanks to GiZ (the German people) for making it available to all of us.

The Greenway Smart Stove is an insulated metal stove, that appears to be a rocket style design with bakalite handles and a metal pot rest and fuel rest. You can see more details in the Greenway Smart Stove flyer.

This stove is marketed as an improvement over the mud Chulha, which is familiar in India.

Practical Action, Kenya

The Upesi stove, also known as the Maendeleo has been successful in Kenya. It has two parts, a simple pottery cylinder with pot rests (known as the liner) that is built into a mud surround in the kitchen. Fuel is fed into the fire through an opening in the front of the stove, and it has no chimney, but it produces much less smoke than an open fire.

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.

Summary of ETHOS Stove Camp, August 3-7, 2009
Dean Still and Nordica MacCarty

Forty three folks attended Stove Camp this year coming from as far away as Norway, Germany, Honduras, and Mexico. Some people were too busy making stoves to be in the official photo. Paal Wendelbo, winner of the $250 prize for most interesting development, is the white haired gentleman two spaces to Dean’s left. The theme this year constellated around health issues. You can see the presentations and results from Stove Camp by visiting http://www.aprovecho.org/lab/index.php.

Stove Camp featured many experiments. We set up a Test Kitchen, in which stoves were tested, making posho (African corn meal mush). Particulate Matter and Carbon monoxide were recorded in both the room air and at the nose/mouth of the cook. We also used a RAD 57 from Masimo to non-invasively measure levels of CO in the cook’s blood before and after cooking. Stoves were also tested under the emissions hood, and practice WBTs were run without emissions measurements. Peter Scott and Dr. Andreatta were successful in creating an aluminum mitad with even temperatures for making injira.
