Open Space is a concept to give freedom to the people. Within minimum given place, people would have access to Fire to cook (good stove), have access to food, water for drinking, source for light (apart from stove, some light from solar powered lamps), place for communication and networking with others and a place for reading books, news papers, etc. These type of "Open Spaces" would be kept in public places, especially for the poor people to access all the above facilities..

Open Space was designed by Dr. N. Sai Bhaskar Reddy..being facilitated under the theme "Be-Cause".. for the urban poor people... http://e-openspace.blogspot.in/

Hi! (little correction: i am a Hungarian born Hungarian citizen, and now living in Hungary again... )

When seeing the design from Haiti we were a bit afraid of using springs for ejection, so we really wanted to push from the bottom.. And that was a challenge with the spikes that make the holes.. And then my colleague had the great idea with the two-way lid. (He is called Attila, I include him in the list) And I dont think it should make much difference that the holes are rectangular.

The other great idea of his, which i am not sure if u can clearly see from the pictures, is that one of the lids is actually a tray that should slide under the briquettes after compressed (and pressed above the mould), and when you lower the jack, the briquettes just stay on the tray and can be moved (we will probably make another one of these, to save time like with the two mould sets with the legacy press). When we were testing the press, we had a little accident with the jack, so I am not 100% sure yet whether the tray will leave the briquettes intact(ish) but the first try when the jack was working was promising.

The fabricators are of a small coop from another very poor region of the country. (They are actually also Roma/Gypsy). A friend NGO set us up with them, and they were really great to work with.

Sure we would be very happy to make a manual out of this, but I first want to wait until we can properly test it and hopefully make a second prototype soon. The material costs were quite high which would be quite good to reduce.

I attach a collection of images and some info on presses that can be used as inspiration. (I think it would be really interesting to experiment with the screw press with the weights).

Thanks for your support! All the best, Nora

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.

Dear Friends

This is very useful.

Save it!

y = 4-08x2 - 0.0036x + 99.996

X = your altitude in meters. Y = the local boiling point (at standard air pressure)

If you know your altitude, it will give you the ‘standard’ boiling temperature. If you know the local boiling point, you can work backwards to get the altitude where you are standing.

Excel cell contents:

=99.996-0.0036Altitude+410^-8*Altitude

where ‘Altitude’ is the cell in which the altitude is located.

A wonderful afternoon with Susan Kamau's Kenya Kitchens Cooking Club. Susan is a Global Alliance for Clean Cookstoves Ambassasdor Chef and we very pleased to partner with her to have a open afternoon at UCHUMI SUPERMARKETS LTD to hold a baking demonstration and discussion about energy conservation, clean cooking, nutritional baking as a business and of course healthy delicious eating!

In 1992, Dr. Maxwell Kinyanjui made the initial prototype of the Cookswell Energy Efficient Charcoal Oven, domestic and business sized convection ovens designed for baking and roasting on just a few handfuls of charcoal. Using a Cookswell Charcoal Oven means zero dependence on electricity and oil or gas for all household cooking needs. This can translate into reducing energy bills by up to 70% through switching to charcoal. The ovens are designed to provide an even heat flow throughout the cooking area so flipping and turning of the food is un-needed. The heat can be controlled from between 150F-450F by using the air inlet. The ovens come with a factory standard alloy-zinc body, steel legs with non-slip feet and have an inbuilt no-mess ashtray and drippings tray. Our ovens range in price from 11,000 Ksh for the smallest domestic sizes that can bake 3 loaves of bread to 45,000 Ksh for our largest heavy duty commercial ovens that bake over 80 loaves per load. Baking is nutritionally a much better and easier form of cooking that preserves the nutrients in the food and allows for a wide array of food combinations that require less water, fat and oil to cook. With the reemergence of knowledge of the health benefits of traditional foods, Cookswell Ovens make preparing all of your best dishes easier and more pocket friendly for a range of healthy meals for your whole community. Free range “kinyeji” chicken with an arrowroot/butternut squash rosemary melody, or sweet potato bread to go with tea in the morning - the options are limitless. For oven users in the commercial sector, a Cookswell Oven will save money and improve quality and standards of service, from optional hot water heater tanks to huge savings on energy bills and even providing heated plates for that extra touch. Cookswells’ quality reflects your choice of high quality in your kitchen products. In order to help us make charcoal a sustainable energy source, all of our ovens come with a packet of acacia tree seeds so that you can plant and grow your own charcoal for future use.

In their presentation at the GACC forum, Paul Means and Chris Lanning take a look at the supply chain problem with using woody biomass as a replacement for charcoal in urban areas, and they propose some ideas for equipment that may overcome those problems, as well as identifying some of the challenges to that approach.

Hi all many of you don´t know me, I start 5 years ago with the help of Nancy Hughes from Stove Team International and with a little help form Carlos Santana, since then I have learn some stove principles desings with Larry Winiarski, 2 years ago the Global Alliance invite me to attend the wood cooking stove forum in Lima Peru, in the opportunities brought along a hybrid stove Rocket/TLUD similar to the DK stove. and I´m working with a metal rocket combustion chamber wich will be done next week, we´ll make some KPT for 2 months before I send pictures, but tomorrow I´ll post some pictures of my hybrid metal rocket-TLUD that I made 2 1/2 years ago.

this what I was talking about, I made this combustión chamber 2 years ago and is working good, I´m desingnig a stove at this momento with one of this combustión chambers. if someeno need plans and pictures just let me know, hofully some can make some imprivements

A few more pictures to clarify how the Rim Fire iCan is built. It is quite simple.

Materials:

• One fan
• Four standard stove pipe parts
• Two tin cans
• One metal plate
• Three angle brackets to support the burner plate
• Six bars to align the cans when stacked.
• Some screws, nuts, and bolts.

To Build the Stove

1. The fan is set facing up on an 8 inch stove pipe trim collar - made in Canada This is a standard stove pipe item. The base acts to keep the secondary air from escaping out the bottom.
2. The fan is then enclosed by a 7" to 6" stove pipe reducer.
3. Next the primary/secondary air mixer is added. Made from a 4 lbs tuna fish can. This is more or less a fixed part of the system. It is independent of the reactor operations.
4. Next the fuel chamber/pyrolysis reactor is added. Made from a 3 lbs Costco coffee can. This is the only can that gets extremely hot. It should be made of a good stainless steel.
5. Lastly, a length of 8" stove pipe is added. it is capped by a standard 8" to 6" reducer. The bottom of the stove pipe sits just inside the rim of the trim collar, which acts to more or less seal the bottom of the system. The bolts are only there to correct for a bad guess and would not normally be used. The secondary air flowing up the inside of this pipe helps to keep it cooler. In operation, the segment of the pipe below the reactor can is very cool.
6. Detail of the fan set on the trim collar. Note: The fan never gets hot. It is nearly impossible for hot bits to fall thru the 5/64ths primary air holes.

To Operate

1. I load the fuel chamber. Add starter. Place the burner plate on its supports & center it;
2. Place assembled and loaded reactor can on the primary/secondary air mixer can;
3. Lower the stove pipe outer shell over the unit. Center it.
4. Ignite the starter via the gap between the reactor side and the edge of the burner plate.
5. To unload the reactor at the end, I simply reverse these steps - using pliers and insulated gloves.
6. With a too fast, single speed fan, a reasonable fuel load of 1,500 grams of wood pellets will last just under an hour.

Cost of this, if wood pellets are $300 per ton, is about 50 cents per run. Fine in the US market, but probably too expensive in many places. Tuning this to work with rice hulls, coffee husks, etc would be importantTuning this to work with rice hulls, coffee husks, etc would be important.

Unfortunately, I do not have access to rice hulls or coffee husks for testing.

Total height of the assembled unit is just over 54 CM.

All in all, this is pretty simple to build and operate.

The first two stoves in the attached i already am making since the past years. And recently, i have been teaching women and soon their husbands to also make their rocket stoves here in the province of Bulacan under a disaster preparedness program by the Save the Children International. They also make their own designs of flowers, castle towers, chess characters, and faces into their stoves.

the drawing in the third attachment is a prototype in process. It is a Holey Rocket Stove with a char pocket on the side and a box as a platform. I hope to finish it in the coming weeks.

The document “Mechanisms for Evaluating and Achieving Efficacy of Household Energy interventions” from

http://community.cleancookstoves.org/user_content/files/002/955/2955562/...

is asking very pertinent questions that the CSI team in Indonesia has been grappling with, and I think making very good progress. I recommend everyone read and ponder the past portion, at least:

1. The plan that is developed will have to be implementable, technically feasible, cost-effective, repeatable, and supported by multiple stakeholders. Will we have capacity to do conduct and enforce testing according to any requirements that are set?
2. To implement any proposed plan, are there additional requirements beyond protocols, standards, indicators, tiers, and best practices? For example, do we need a serial numbering system? What are the data sharing needs?
3. Stove usage and stacking is a particularly challenging issue to address. What aspects can be addressed through standards versus using feedback from customer purchase decisions? Does the mechanism change depending on whether stoves are subsidized or not?
4. What are the short-term practical mechanisms, and what are the long-term implementable mechanisms? How can we plan to move from the short-term to a sustainable long-term solution?

They are correctly identified as ‘over-arching questions’. There are other questions in the rest of the text that will be of great interest to testers and developers.

More pictures of Jed's work on Stoves and also a pdf of Jed's work on stoves and ovens

Also take a look at http://www.stoves.bioenergylists.org/Holey-Roket-2013
for other pictures of this type of stove.

Jed started with the Rok Oblak Holey Roket stove:
http://stoves.bioenergylists.org/taxonomy/term/243

and has been making improvements to the design detailed in the pdf, and has these lovely stoves made with the help of the artists he's been working with in the Philippines.

These are the features that he's working to include in the latest batch of stoves:

• A side fed fuel chamber allows for continuous cooking.
• Better flame control.
• Eliminating the risk of handling hot char.
• Allowing for multiple fuel types
• Clay is less expensive than metal.
• Clay stimulates employment, social inclusion, and creativity
• Clay stoves are heavier and brittle but they outlast equivalent metal stoves, some lasting for longer than 3 years of continuous use.

Stove Camp 2013 ----- July 22-26,2013 ----- Cottage Grove, Oregon
“Great Stoves” to meet the Global Alliance standards for clean, efficient, and safe cooking.”
Co-hosted by InStove, Aprovecho Research Center, and Paul “Dr. TLUD” Anderson
The Global Alliance for Clean Cookstoves is establishing standards, and this summer’s stove camp is going to focus on the design and delivery of stoves that meet them. We will be looking at the various proposed tiers of stove performance and see which stoves fall into what classifications. We’ll also be exploring design considerations for producers who are interested in building top-tier stoves.
The Aprovecho team will lead the testing – an opportunity for attendees to conduct emissions tests of their stoves “under the hood” in both a test kitchen and in simulated field conditions.
TLUDs (“Top-Lit Up-Draft” stoves) are achieving some impressive results measured by these new standards, and we’re fortunate to be joined this year by Dr. Paul Anderson “Dr. TLUD” who will be leading workshops and sharing the current state of the of art of this clean-cooking technology with Stove Campers.
The InStove team will demonstrate their “Stove-Factory-in-a-Box” method of producing high-performance, institutional stoves anywhere in the world, and will conduct workshops on adapting this production methodology for household stove designs. InStove will lead workshops on improving stove safety and will demonstrate their newest-generation briquette-making presses, medical-grade autoclave, and water purification system.
Stove Camp is open to all comers, and regularly attended by – designers, producers, humanitarian program implementers/administrators, folks interested in environmental issues, women’s advocates, student interns, and some amazing inventors. We all share the goal of serving humanity – particularly in the developing world – by finding viable solutions for some intractable global problems.
Tuition is a low $300 USD, and people have the option of camping out by the river on our campus or choosing one of several affordable lodgings in our beautiful, small, Oregon town. We expect the largest turnout ever this year, so reserve a spot today!
Schedules will be available in early June.
For details, email Stella Strother-Blood at: Stella@instove.org. or Mike Hatfield: apromike@gmail.com
Registration: Mike Hatfield: apromike@gmail.com

OK, the focus is not the best but this is the require for submission of stove samples.

The potential order size is large -
