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.

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.

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.

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

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.

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!

On February 22, 2012 I did three boiling tests.

The first test was carried out on a normal propane gas burner that I have in my kitchen.

http://youtu.be/w8OdW_GEhWo
Here it took 6 minutes and 6 seconds to bring one liter of water to a boil.
The burner shown in this video is a very efficient premix gas burner.
But since it operates solely by means of convection, its performance is not optimal.

The second test was carried out using the 150 gasifier:

http://youtu.be/jK3UTe1Lxqk
Here it took 3 minutes and 42 seconds to bring one liter of water to a boil.
Note that the same pan without a lid was used in these two boiling tests.
Here heat is transferred by both convection and thermal radiation.

The third test was carried out using an insulated electric water kettle, as shown here:
http://dl.dropbox.com/u/22013094/150%20Gasifier/Boiling/IMG_1042.JPG
Here it took 3 minutes and 25 seconds to bring one liter of water to a boil.
In this way I was able to compare the two previous results
with what could be considered to be the fastest way to boil water in a kitchen setting.

I wonder if you have found any technical design literature for this added radiative mesh? (Materials, wire diameters and spacing, etc?)

I have no theoretical understanding with regard to what is happening with the wire mesh dome.
I tried flat wire mesh, and this did not work at all.
The wire mesh has to be in the form of a dome to accommodate the small diffusion tail that you see here:
http://youtu.be/WXZvvoxCm1g

I tried wire meshes of various apertures.
If the aperture of the wire mesh is too big, the flames are not contained properly under the dome.
If the burning of gases takes place above the dome, the dome does not turn red hot.
This week I will experiment with much finer wires and apertures.

Also, if I turn down the primary air to a point where much less gas is produced,
combustion no longer takes place at the burner holes but within the apex of the dome.
Here a most unusual but stable cloud of burning gases is formed.
