Hello stoves community,

At ETHOS 2009 we held a panel on stove safety, bringing in viewpoints from corporate standards development, national standards certification, and small to medium scale developers. The team led by Nathan Johnson (Iowa State University) included Crispin Pemberton-Pigott (New Dawn Engineering), Casper Thijssen (Philips), and Karabi Dutta.

The panel gave a comparative analysis of how different stove industries (multinational corporations, medium-scale companies, NGOs, small developers, etc.) addressed fundamental stove safety questions. These topics included:

a) applicability of standards and regulation;
b) incentives and benefits
c) facilities and equipment availability
d) cost vs. benefit
e) resulting action

We determined that each type of industry has a different perspective that influences their path or actions towards a safer stove. And that all sub-industries may not produce safer stoves given the same incentive mechanisms or policies. As such more than one path to safety may be needed to reach the greatest amount of end-users (and producers). The panel ended the discussion with an overview present work in stove safety with recommendations for next steps.

Please view the attached file for more details. I will be leading a group in 2009 to work on the following: assemble database of injury data, b) analyze incentive mechanisms, cost/ benefit, c) development of lab testing procedures for different stove categories, d) publication of findings/ results, and e) look for partnerships with international agencies to support safer stove design and production.

Please contact me if you have any questions. There will be more updates to follow. Best,
Nathan Johnson

This is an experiment using biomass in the KEROSENE WICK STOVE. http://e-kerbiostoveexp.blogspot.com/ (for more photographs) The stove was lit at the top using a little amount of biomass soaked in kerosene. The fine holes of 1 to 2 mm located all along the inner and outer frame are useful in achieving very good bluish flames. The flames continued for 30 to 45 minutes duration. Only at the end the performance was bad, the option was that, a lid was used to shut down safely. The fire was very high (Reasons I am not sure). If one does not have enough kerosene, and in emergency one can use the kerosene stoves too with fine wood shavings as fuel. The end product is very good biochar. I am thankful to TOM REED for explaining the functioning of a Kerosene stove, which was the motivation for doing this experiment. http://listserv.repp.org/pipermail/stoves_listserv.repp.org/2009-January...

This is the prototype of Magh series "Magh Utham Woodgas Burner". http://e-maghutham.blogspot.com/ This is a natural draft burner (forced air is optional). Low cost, low weight, easy of operation, easy to collect the biochar by rotating the combustion frame and easy to reload it. As it is can be used for boilers / institutional stoves / domestic cooking / etc. The performance is good. There could be some more improvements in its design to increase its performance. For details and photographs see the link http://e-maghutham.blogspot.com/ . The term "Utham" refers to "Best" which is part of the name of Prof. K. Purushotham Reddy a very well known environmentalist in India.

Magh CM-II natural draft woodgas stove http://e-maghcm-ii.blogspot.com/, it is a very low-cost stove for heating and generating charcoal. It can also be described as a mini-charcoal making metal kiln. Instead of incinerating biomass generated from home gardens / any other dry combustible material generated as household waste usually throw into the garbage bins, can be used here. The leaf litter, dry twigs / sticks, chips of wood, wood shavings, etc., are very much suitable.

Dear Stovers:

I am attaching [the image above]that may be of interest to the stovers.

Here is an unsolicited commentary on our new XL WoodGas Stove, available at

Woodgas stoveWoodgas stove
along with our gasification books.

We have recently learned that BP is manufacturing a VERY similar stove
and selling them (only in India) in their equivalent of Walmart. I hear
they have already sold 100,000. Sounds like we are well on the way to
getting a "Billion Improved Stoves" out to the developing world.

If you cover the combustion air holes with aluminum flashing or sheet
metal screws the stove also makes a good gasifier.

Onward,
