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.

Roth, Christa

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.

Putting the Cook before the Stove

This study Putting the cook before the stove: A user-centred approach to understanding household energy decision-making from the Stockholm Environment Institute takes a look at existing cooking patterns in the Haryana State in northern India where several improved cooking stove projects have taken place.

In the study location, the researchers extensively interviewed householders about their stove building and cooking habits. In this area, Mothers and daughters often build portable or fixed place Chulha stoves that they use to burn dung, wood and straw. The authors did a great job of interviewing stove users and attempting to understand from the users point of view, why these unimproved mud stoves were used more often than the improved stoves that they had available.

Burning dung, is a vital part of the local economy and culture of this place, and the women cooking, use the dung for low simmering, in a purpose-built mud stove. It doesn't look like that stove usage was effectively replaced by the improved stoves that have been introduced in this area. The local cooks also pan fry and then bake roti, which they bake pretty easily in the local chulah stove, and the Philips and Oorja stoves don't have a place to do this baking.

It seems like cooks in this area don't mind having multiple stoves for different purposes, and this type of study is essential to understanding what the cooks needs are before we try to address those with improved stoves.

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

BSH has discontinued the Protos Plant oil family of cookstoves

24 August 2012 - 3:14pm

B/S/H BSH Bosch und Siemens Hausgeräte GmbH has decided to continue the Protos plant oil cookstoves that they had been working on in Indonesia, and instead made the technology publicly available for commercial manufacturers:
http://www.bsh-group.com/index.php?12765

The family of plant oil stoves, including the Protos stoves, were designed to be safe, and reliable cookstoves for low income residents of Indonesia. BSH found that despite having a lot of plant oil available, there was no reliable network of distribution of that oil, and it was keeping users from being able to use the stove. The plant oil stoves also require a lot more cleaning and maintenance than kerosene stoves. Between the difficulty in getting fuel, and the additional maintenance, it was difficult to expand the stove project beyond the initial pilot projects, and BSH eventually concluded that this project was unfeasible.
