A super low-cost, blue-flame rice husk gas stove was recently developed in Indonesia to provide households with an affordable clean-burning cooking device using rice husks as fuel.

Within the 3 years of development on rice husk gasifier stove, PT Minang Jordanindo Approtech has finally come up with the super low-cost, blue-flame rice husk gas stove carrying a selling price of US$10 to 15, which is very much cheaper as compared with the previous model with a selling price of US$20. With this development, consumers don’t need to amortize for the stove, as what is currently practiced in villages in Indonesia, for them to acquire a unit of the stove in order for them to save money on fuel. Moreover, this stove is now made available to end users at a low cost, freeing the distributors from the task of devising financing schemes just to make the technology affordable to the local households.

As shown, the stove consists of only few parts. It was designed and made so simple to maximize the use of materials and to simplify the production using locally available resources. This stove model has the following basic parts: (a) the casing is made of tin can and can be bought at a very low price from a Can Factory; (b) the reactor can be subcontracted from a sheet metal manufacturer as well as the stove cover
and the burner; (c) the fan, which uses DC 12 volt, 2 watt supplies the required air to gasify rice husks. The flame coming out of the burner is bluish in color, which indicates a very clean gas. It has low black carbon emission of about 50 ug/m3 and below. The CO2 emission is about 0.6 kg CO2 per kg rice husks.

[MAGH 3G]( http://e-magh3g.blogspot.com/ ) is an adaptation stove. All types of biomass, briquettes and charcoal can be used for cooking. This is an all in one stove.

It was found that many families have at least two or three types of stoves in rural areas for using types of biomass as fuel. Now with just one stove they have the freedom to use all types of Biomass as fuel.

There is an option to control primary air, to control air from the fuel feed side opening, and secondary air (while using TLUD adopter). Weighs less than 2 kgs, 9 inches in height and 7 inches diameter. Most convenient for regular use, travel, relief, refugees, etc. Reusing metal sheet, these stoves are completely hand made. The cost of each stove piece is $5 (USD).

This stove is being facilitated under the "Good Stoves and Biochar Communities" Project, implemented by GEO with the support of GoodPlanet.org This is one of the 40 stoves designed by Dr. N. Sai Bhaskar Reddy, GEO http://www.e-geo.org http://www.goodstove.com/ . For more details visit http://e-magh3g.blogspot.com/

I’ve been following a couple of different groups and discussions to learn about biochar for about 6 months. Id like to share what I’ve been learning and ask a couple of questions.

My purpose is to use biochar as a component in biological soil synthesis and buffer for use in a vaquaculture growing system.

I have been making small TLUD stoves, observing modeling tweaking making another.
