    I finally got to lite it up. Again as some of you know my interests are
    varied and doubled up. I want to burn what people may be throwing away or
    burning to add to green house gases and global warming. I am also interested
    in Char and Terra Preta as well as atoll soils are regarded a notoriously
    weak. For those not in the tropics my fuel here are chopped up pieces of
    the mid ribs from coconut palms. These do take some time to gather dry and
    chop but some place these are nearly ubiquitous as rice hulls or sugar cane
    scraps and their price may be right for many $0.00.

    now its goingnow its going

    Over all the stove owes serious thanks to Paul Anderson, who kept after me
    to make it, and Paal Wendelbo and Sai Bhasker. They all contributed ideas
    for me to digest. To some I have joked this hydrid should be called the
    Champion Pekope Smokeburner. I like the simplicity of Paals and Pauls
    secondary air gap. I like Sai's idea of fins to promote swirling and
    mixing. I worry a little about Pauls protruding handles so I changed that a
    little. Paul uses a riser to promote draft so I kept that and put Sai's
    twister fins inside it. .

    Lighting it off was not so easy and took three attempts, and much more smoke
    that I would have liked. The stem pieces were not catching fire well. I
    finally got it going with some copra chips and small pieces of frond riblets
    as well, with a dash of WD 40. Once it finally caught in about the 6th photo
    the flames do appear to be curling around in the riser can, and in the 7th
    the standing flame has a nice twisty shape. The burn was not as long as I
    had hoped for as by say 35 minutes it was definitely dying down. The fuel
    was quite chunky and not very tightly packed, probalby why. There also was
    char material left in the bottom but I should have pulled the burner can a
    few minutes earlier.

    The reuseable mesh disk in the bottom of the burner, a tin can, and the
    simple handles needing 4 small nuts bolts and washers is not very
    technically advanced, meaning making multiple standby drop in burners is
    "from the dump" cheap. The way I have suspended the burner by its handles in
    notches in the outer cylinder is a step towards further simplicity and means
    changing in and out additional fuel canisters is very simple. (Please though
    not one make jokes about the sloppy mis-sized handles) A craftsman would
    have each canister identical. The principle should be clear to all though.
    Paal was much the source for the straight simple outer cylinder but the
    hanging basket burner means no spacers or legs and only simple holes for air
    entrance. I do see some areas for further testing here...the gap between the
    inner and outer housing and the number and size of air holes allong the
    bottom of the outer cylinder. I have never seen Rajan's stoves but a SS
    outer cylinder for appearance, a cooler shell and longevity with a drop in
    sacrificial burner might be worth considering.

    Since Paul brought up longivity in TLUDS this morning, I do hope that my
    aluminum outer cylinder will not get hot enough to have a problem. The
    tincan liner simply means drink some more milk and make another one, not big
    deal at all. It may not be a Stradavarus, really more of a washtub bass,
    but now I can play with the tuning it and my fuels. The main thing is it did
    work sort of and I believe a couple of my ideas have merit. Anyone out
    there in the larger world who sees a use for any of this please help
    yourselves. Also please pass along any suggestions. It is interesting the
    the Legislature and hearing got in to fuels, solar and sustainable issues
    today.

    If Tom does not think this is to simplistic he might want to clean it up and
    post it.

  • Spinner a TLUD - Experiments with biochar and TLUD stove

    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.

TLUD Fan

  • 5 Gallon (22-liter) TLUD Stove for Institutional Use and Biochar

    Paul Anderson, 2009 SeaChar Stoves Workshop

    The efforts at SeaChar (Seattle Biochar Initiative) produced a 5-gallon (22-liter) TLUD.

    "On Saturday, August 1, Seachar hosted Dr. Paul Anderson (Dr. TLUD) for an all-day workshop in the construction of Top-Lit Up Draft (TLUD) cookstoves. The stoves can quickly be constructed from commonly available materials, and produce charcoal while providing heat for cooking (or other uses). Paul’s TLUD stoves have been tested and shown to produce very low emissions of CO and particulates. The stoves can provide benefits wherever people rely on biomass for cooking. TLUD stoves use a wide variety of small pieces of biomass for fuel. The clean burn greatly improves indoor air quality compared with open burning and many other types of stoves. In addition, the charcoal can be used as biochar to improve soil fertility, sequester carbon, and potentially provide a source of income through carbon credits."

    For More See: http://seachar.org/wordpress/?p=176

    The focus was for making biochar, but this size of TLUD will be highly appropriate of institutional-size cookstoves in the developing countries.

    1.0 EXECUTIVE SUMMARY

    1.1 GOAL OF THE PROJECT
    To promote energy conservation and reduce deforestation in the sugar cane growing in Western Kenya.

    .1.2.1 Specific Objectives
    To Promote TLUD gasifier cookstoves and five biogas planter in Western Kenya
    To provide and service 20,000 TLUD gasifier cookstoves and 5,000 fireless stoves..
    To train 150 women and youth groups in production, repair and sale of energy saving equipment
    To train schools and communities on energy conservation and use of renewable energy technologies.
    To develop an energy equipment workshop for production, service and sale of improved cook stoves and energy saving equipment.

    1.3 ACTIVITIES
    The activities in the project will be
    Community mobilization on energy conservation, forest resource management and effect of indoor air
    Training in design, manufacturers and sale of renewable energy equipment and technologies i.e. biogas, TLUD gasifier cookstoves.
    Networking on renewable energy conservation i.e. knowledge sharing and information dissemination.
    Manufacture TLUD gasifier cookstoves, and five Biogas planters

    2.0 STATEMENT OF COMPLIANCE WITH PARTNERS
    This project will be carried out within the Nile Basin in Western Kenya. The same area is sources of Nile and other small tributaries. The project will promote energy saving culture and lead to sustainable use of forest resources while contributing towards the Kyoto protocol implementation. While noting that firewood is the major source of energy within the Nile basin and Methane, is 20 times more potent CO2 and hence its use in biogas energy is encouraged in managing green house effect.

    3.0 PROJECT AREA
    Western Kenya has a population of over 5 million people of which 80% depend on agriculture for livelihood and over 70% use firewood as fuel source. A survey has shown that all boarding schools use firewood and charcoal as fuel for cooking hence pressure on forest cover. Sugar cane growing in Mumias, Malava and Bungoma is a heavy user of trees as firewood. This combined has led to heavy exploitation of forests and trees for firewood hence a danger to the water catchments area.

    4.0 PROBLEMS/CHALLENGE
    Sugar cane cultivation in western Kenya, which started in mid 1970’s, has accelerated the rate of destruction of trees due to high population density has further compounded the problem of destruction of forests and trees hence threatening the very source of water within the Nile Basin. Schools continue to put pressure on forest due to their high demand for firewood to use in cooking with highly inefficient open fire stoves. These project will develop biogas as an alternative source of energy, promote economical use of energy in institutions and homesteads through use of energy saving stoves create employment for people trained in production and service of the same and of the same and efficiently generate and use the highly potent methane from farmlands through biogas plants.

    5.0 RATIONALE
    This project meets the requirements of MDG's and Partnership for clean indoor air broad objective. The project will support community driven effort and will address environmental threats on local scale within the Nile basin region in the area of development and use of alternative energy and construction materials. In the process of carrying out participatory planning and appraisals for Musamba, Matungu, Kholera and Khalaba, the villagers expressed the desire to get cheap alternative to fuel firewood energy and alternative to open fire 3-stone cooking method. In all this areas, villagers expressed their fears that trees are disappearing and as a result they use farm wastes like maize stalks for firewood. The same should be used to replenish soil fertility after the crop season and should not used in the kitchen as firewood. Others were resorting to cane trash and remnants.

Briquette Stove

  • GEO FUEL BRIQUETTES

    GEO fuel briquettes

    is a very low cost technology, and also for making briquettes with very less effort. This is screw based system, requires very less energy and space to operate. Briquettes can be made using human power, convenient for young or old in making briquettes from various types of waste material. Small pieces of waste papers, sawdust, leaves, wood shavings, rice husk, etc. can be used as raw material. Any sticky material available in abundant can also be added if required for producing compact and strong briquettes. The cost of each such device made up of iron is less than $8 (USD) or Rs. 400. Various types of stoves are available for using the briquettes, including some of these AVAN and MAGH series stoves can be used. Magh-1 stove with little adoption can also be used for briquettes as fuel. We can also make and use special stoves for the briquettes as fuel.

  • Rocketstove.org is Online

     

    Dear friends,  

    www.rocketstove.org  is finally online! And our friend John page from Aprovecho has agreed, at least in the short term, to be the new web administrator.   

    Our goal is to make this a practical site. For example the key content that I have right now is the Institutional Rocket stove  design tool that will allow users to  generate a custom set of institutional stove plans (brick and metal)  just by inputting pot size and a few other  key inputs .Ideally this would be the site that users would  turn to for specific plans on how to construct  rocket stoves , bread ovens, dryers kilns etc. If you have content that features step by step stove plans please register and then post them to the site.  (note e: g it might take a day or 2  to approve your registration  as I have to manually  accept each registration ) .  Registered users will eventually be able to  produce their own home page if desired , or just add contact info. Foremost I would appreciate it if we could link your webpage to ours and vice versa.

    The second goal of the site is to link people in the stove community by interest and region . For example someone could turn to the site and be linked to stove producers, purchasers and/or researchers in  China, Guatemala,  or Uganda. As the site grows into phase two we will add more functionality (ordering stoves online, visitors donating to specific projects, etc)   but initially I would love to collect as many links and content as possible in the next few weeks for the launching of the site . 

    At present this is a volunteer effort , and John and I would appreciate any form of support (financial or otherwise) from the stove community to get this web page up and running. The webpage was only made public last week so we are still very much in our infancy so we appreciate your patience as we smooth out the wrinkles. 

    Also, Please feel free to forward this e-mail to anyone you think might be interested. 

    Peace

    Foreword

    The Building and Construction Improvement Programme (BACIP), operating in the Northern Areas of Pakistan, is a project under the Aga Khan Planning and Building Services, Pakistan (AKPBSP). The programme is financed by PAKSID, a collaboration between the Canadian International Development Aid (CIDA) and the Aga Khan Development Network. The BACIP Programme Director is contracted through the Netherlands International Development Co-operation Programme (DGIS). BACIP works in co-operation with other Aga Khan Development Network Institutions (AKDNI) in the Northern Areas and Chitral, Pakistan. During 1999 and 2000 some 40 staff members, consisting of architects, engineers and social workers, have been involved in the BACIP programme activities. In addition, more than 200 village-based male and female resource persons assist on a voluntary basis in the implementation of the programme.

    The present programme (to end-December 2000) consists of the development and introduction of house improvements (more than 40 different types) for traditional and new houses which are useful for villages in remote areas. Technology and skills development among local entrepreneurs has been initiated to enhance the delivery of the house improvements locally. Participatory cluster and village planning is a part of the process as well and community discussions have begun for determining appropriate housing locations to avoid building in geographically hazardous areas. Parallel to these mainstream activities, attention has been given to the design of new schools. As many of the technologies being applied in the new school designs can also be applied in houses, the demonstration effect would have a high impact on the youth and future house builders.

    The present report gives an overview of the different types of stoves that have been developed by BACIP. The designs are improvements upon the existing stoves in terms of durability, cost, fuel efficiency and manufacturing techniques. The designs have been repeatedly modified to suit the needs and acceptability of the people.

    The BACIP stove (buchari) has been developed on the basis of the AKPBSP (formerly the Aga Khan Housing Board) buchari which was introduced about seven years ago and more than 10,000 installed in the region. The new models have been fitted with various options, such as the top-oven, improved chimney, warm water facility and various chapatti plates for making bread.

    Firing Things UpFiring Things Up

    See slide show attached. I did this in conjunction with a Woman's Club, "Kare in Okrane." Essentially, "Women of the Break of Dawn," a reference to women getting up a the break of day to prepare for the family's day. We did have hundreds of observers and a strongly expressed interest. In this case the rocket stove had the clear edge. Burning fuel is what people understand. Women have been doing it at their grandmother's knee since childhood. The Solar oven probably came in second. Here it was much like a microwave. I had to constantly open it up and invite people to touch the pot. Ouch, that it hot, hey it does work. What can you cook in it? Sadly the TLUD was more of curiosity. . The kerosene/propane like flame did surprise people, and I repeatly brought up charcoal and terrapreta as a benefit over time. However, the small size and short burn worked against it. I simply switch between two to resolve this. Best Regards to all Michael Trevor mtrevor@ntamar.net
