Here is some pictures of the Jiko Bomba casification cookstove.
The first shows the two part of the stove with pellet as fuel in the firebox before fire is lit.
Second show the stove burning.
The third the same, in the end of the gasification.
The forth shows the charcoal stage where the pellets remains as glowing carbon. A pot can be put on top of the bottom part of the stove, there are three supports for that.

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.

Aprovecho's larger stoves - the instiutional stoves group, have now branched out and become

Institutional Stove Solutions (inStove)

http://instove.org/

They are using the same rocket stove, and have perfected a 60L stove for institutional stove.

They are focusing on schools and other institutions, and have attached an autoclave for hospital and clinic use.

They've found a way to do "Stove factory in a Box", and have perfected a way to build the stove with local labor, and with all tools provided in the factory box and requires only a small generator to operate long term. AIR JORDAN

Rogerio Carneiro de Miranda shared his new video that highlights the features of the Ecofogão in Brazil.

It is is a rocket style stove that uses wood to heat a cast iron griddle and an oven. It is an efficient stove that also includes an chimney, and the option to build it into an attractive and functional kitchen island. They also have an option that heats water (for washing or bathing).

For more information, and pictures, and to buy the stove, see their website:

Biomass Stoves from Indonesia

Nurhuda, Muhammad

Muhammad Nurhuda from the Physics Department, Brawijaya University
in Malang, Indonesia

They have developed a various biomass stoves ( Kompor Biomass ) The fuels also vary from chopped woods/twigs, pellet, palm kernel shell, hazelnut kernel shell, corncob, etc..

And they have a nice collection of YouTube videos:

UB-03 with Palm Kernel Shells http://www.youtube.com/watch?v=g7TZn6YGOcI
Using the UB-03 Stove http://www.youtube.com/watch?v=KOba6FobfrQ
UB-03 Jumbo http://www.youtube.com/watch?v=b70z9-0nK6E

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.

The latest one

http://www.youtube.com/watch?v=b70z9-0nK6E

is devoted for institutional cook stove or small restaurants.

Very recently, we have also developed a new rocket stove. The combustion in this new rocket stove is improved by introducing counter-flow burning mechanism.

Why pay someone else's charcoal bribe?

Did you know that more then half of the price of a bag of charcoal in Nairobi is money needed for paying bribes to get illegal bush charcoal to town? Save your money (and Kenya's forests) by making your own charcoal at home using only your own twigs and pruned tree branches. (or timber mill waste)

Dear all,

For over two years we have been telling people that in two weeks or so we hope to have the mud Rocket Stove website updated. It finally happened. Flip has worked countless hours on this. This morning she shouted out, "The baby is born!"

Thanks to Larry Winiarski for all the mentoring and watching over us. Without Larry and the Good Lord this would have never happened. http://www.rechoroket.com/Home.html

Happy New Year,
Jon and Flip
