IFB stainless liner school rocket stove
IFB stainless liner school rocket stove skirt detail

On a recent trip to Haiti, I completed the first prototype of a new school rocket stove. This one has a 26 ga 330 stainless steel firebox liner, 2½" insulating firebrick walls, and galvanized steel outer shell. The skirt is 304 stainless inside, 1" ceramic fiber in the skirt floor and walls, and galvanized steel outer. The mouth and firebox are 6½" x 6½". The pot is 40 qts with the top diameter about 1/4" larger than the diameter near the bottom, and is imported. The locally available spherical bottom pots made skirt construction extremely difficult. We hope to someday produce this stove in quantity at a combined vocational school/stove factory.M2k Tekno

In my continuing quest to use readily available manufactured materials for stove construction, here is the steam pan charcoal stove with "perforated lollipop" air control. It is a 1/6 size steam pan (roughly 6" x 7" x 4" deep) inside a 1/2 size (roughly 10" x 12" x 6" deep) with 1" ceramic fiber board insulation between. The charcoal chamber is lined with expanded stainless steel to extend the life of the inner pan and improve air flow. Army surplus D rings are used for pot supports. Threaded rod for legs. It can be easily disassembled for repair. It has a small charcoal capacity like the BURN's Jikokoa (formerly Tank).
I plan to eventually build a two burner version in a full size steam pan.Nike

On my trip to Haiti in March 2016, I finished the ammo box stovetop oven. It is made with two ammo boxes, ceramic fiber board insulation, some stainless steel sheet, and various hardware. The oven chamber is 13" x 13" x 5". I plan to add split firebricks on the floor for use as a pizza oven. It fits on a household rocket stove but could be used over virtually any heat source.nike black leather school shoes clearance outlet

sink charcoal stove
rebar inverted pyramid charcoal stove

The inverted pyramid rebar stove is ubiquitous in Haiti. Lots of radiation and convection away from the pot. No air control. Pot is often placed directly on the charcoal which quenches the charcoal and interferes with good radiative heat transfer.
I cut up a scrap stainless steel kitchen sink, built a sheet metal outer box, put in 1" of ceramic fiber board insulation, and added legs and pot supports. The inverted pyramid grate will have the legs shortened and be placed inside the "sink". A slide gate with sets of progressively smaller holes will be added to the "drain" for air control. nike

TOASTER SLOT BRIQUETTE STOVE
I have been designing some briquette burning stoves for El Fuego del Sol, which is making square fuel briquettes from paper, cardboard, and sawdust in Port au Prince, Haiti:
https://sites.google.com/a/elfuegodelsol.com/elfuego/
The stoves are loosely based on rocket stove principles. My latest stove is inspired by the toaster. Briquettes are like thick pieces of bread. For good combustion they need to be surrounded by air and slightly separated from each other and the liner wall. This design holds 4 briquettes in two vertical slots of expanded stainless steel. As they burn down, new briquettes are added through insulated swinging door flaps.
Wrapping new briquettes in a sheet of paper before insertion ensures quick ignition and minimal smoke production.
Air comes in the front and bottom and can get to all sides of the briquettes. The insulated doors block much of the radiant heat from the upper briquettes from escaping out the front and keep briquettes from rolling out of the stove.
The liner will be surrounded with insulating bricks and have a galvanized steel outer shell. There will be a pot support frame and sheet metal pot skirt at the top.
The concept should also work well with round briquettes and dung fuel.

Hi friends,

I have reported to many of you how fun and successful my cooking demonstration with Dr. Paul
Olivier's rusk husk burning TLUD was on my 1st day back in San Jose. My thanks again to friend and frequent SeaChar volunteer Birgit Lendernick for hosting and organizing that. So fun, great food, great conversations and the stove's clean blue flame impressed everyone there
It has been an absolutely exhilarating ten days, since my MEPE bus rolled into Puerto Viejo. Yesterday E.F. promoter, Thierry Mangel and I conducted a biochar buy-back day in the Bribri communities of Amubri, Suiri and Sueretka. We worked closely with the organizers in each community and although it involved lifting and transferring approx. 1200 lbs of biochar from homes to truck, to boat, back to truck and then off-loading. It went great, everyone coordinated well. After stopping at APPTA to pick up the last 10 sacks of biochar that we had inventoried there. We off-loaded and dry stored 565 kilograms in 54 sacks. This gives us enough to meet the order which we have received from a researcher at CORBANA. http://translate.google.com/translate?hl=en&sl=es&u=http://www.corbana.c...

CORBANA is the research and farmer education arm of the Costa Rican Banana industry. They have one of the most sophisticated soil testing laboratories in the country. They will be initiating a three year long controlled study program evaluating the use of biochar on banana cultivation and field practices. This will be the 1st of several orders as this program gets underway. We will enjoy full access to the data from the project as this very important relationship develops. As I have said recently I am not so impressed with how much more biochar we have been selling this year as I am by how influential some of the parties buying it are.

Rogerio Carneiro de Miranda shared his new video that highlights the features of the Ecofogão in Brazil.

It is is a rocket style stove that uses wood to heat a cast iron griddle and an oven. It is an efficient stove that also includes an chimney, and the option to build it into an attractive and functional kitchen island. They also have an option that heats water (for washing or bathing).

This stove is designed to work with Vetiver Grass, they also have plans to encourage small scale productions of Vetiver grass straw pellets for use by the wider Haitian community.
