Avani charcoal stove http://avanicharcoalstove.blogspot.com/ is designed using the most common empty oil tin cans (15 liters) available in parts of India. Steel mesh, rods and a forged iron grate are also used. This stove can be made with less skills. The steel wire mesh used inside, protects the tin as well draws in air. Other liners like clay, and any other material can also be tried. Recently trained women and youth in its production at Avani - an organization at Berinag, Pittoragarh District, Uttarakhand (Himalayas), India. Here the pine needle charcoal briquettes are used. This stove has some common features of My Home Stove 2. http://myhomestove2.blogspot.com/ This is light weight, requires less skills to make it, convenient for adoption.

"No smoking" while cooking through use of efficient good stoves. There is a need to facilitate 1 billion good stoves. This calendar with pictures reminds us this challenge.

The temperature of the flame is around 400 to 500 degree centigrade and reaches maximum of 700 degree centigrade. Convenient for cooking all types of food. http://myhomestove.blogspot.com/ This stove lasts longer due to use of steel mesh inside, which is low cost and easily replaceable.

The stoves design and principles are explained with simple sketchs. Many stove designs are existing, but most common designs are presented here.


[MAGH OPEN STOVE](http://e-maghopenstove.blogspot.com/) is an institutional fixed woodgas stove. This stove is useful for cooking needs of up to 100. With primary and secondary air controls it is easy to operate and highly efficient. For making this stove, "Magh CM" stoves are used inside. This stove is installed at "Open House", Hyderabad, a place for destitute youth for cooking their own food, shelter, studies, etc. Implemented under the "Good Stoves and Biochar Communities" Project, Implemented by GEO with support of GoodPlanet.org France. Stove design by Dr. N. Sai Bhaskar Reddy. For more details visit http://e-maghopenstove.blogspot.com/

[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/

[Magh CM Laxmi [MCL]](http://e-mcl.blogspot.com/ "MAGH CM LAXMI WOODGAS STOVE") is a Natural draft woodgas stove. It is a modification of [Magh CM ](http://e-maghcm.blogspot.com/)for convenience of using all types of Biomass as fuel.

In many villages power is rarely available or available for few hours. In such a situation peoples' priority is for Natural draft stoves as compared to forced air stoves. The control on feeding fuel to the stove is another aspect, which people prefer. And more importantly the community wants freedom regarding the type of fuel to be used. They dont want to have stoves for different types of fuels, as they cannot afford as many stoves as types of fuels.

Magh CM Laxmi evolved from Magh CM. One of the user of Magh CM Ms. Laxmi, Peddamaduru village, has removed the fan and started feeding the sticks from side openings. She is able to use this stove with wood shavings and the sticks. She could use this stove for large scale cooking (12 members), during one of the festivals without any problem.

Keeping in view the adoptation factors and convenience of cooking MCL design is finalized. In honor of Ms. Laxmi the stove is named as [Magh CM Laxmi (MCL)](http://e-mcl.blogspot.com/). By increasing the height of the stove (chimney effect) the soot has been reduced.

Apart from using sticks, it is also convenient to use woodshavings / pieces of wood / leaves / dung balls / dung cakes / pellets / any small pieces of biomass fuel through the elevated side feed tray (its inclination can be controlled for fuel to slide down into the combustion zone).

In both Magh CM and Magh CM Laxmi the design enables the user to control the flames in the stove through primary air control shutter, convenience of removal of biochar. This stove costs about $6. For more information on [[Magh series stoves]](http://www.goodstove.com)
