 Quad – 2012 to Present
Quad Flat Assembly

The Quad TLUD has features for easier production (using tabs and slots, and zero rivets), easier shipping (as flat-pack pieces), local assembly, and greater stability and coolness of four wooden handles that serve also as legs. Without question, there will be further improvements as the number of users increases and they provide feedback. For example, households using the Quad TLUD stoves in various refugee camps could make suggestions that outsiders might fail to foresee. Jigs, tools and methods for making flat-pack pieces are being prepared in the USA for availability to stove projects worldwide.

Material: Sheet metal and 4 wooden handles/legs

Cost: Mwoto and Quad TLUDs sell for approximately US$15 in Uganda, and should eventually cost less, especially if purchased in bulk as flat-pack pieces to be assembled by a local project.

Dimensions: Currently one size, but size can be easily changed: Height: 19” (48 cm), Square footprint 12 x 12” (300 x 300 mm); Fuel cylinder height 14 “ (36 cm) with diameters from 5 to 7” (12 to 18 cm).
Test results of Quad and closely related TLUD stoves such as Mwoto and Champion:

CO & PM Emissions: Consistently the lowest for any of the natural draft stoves that burn solid biomass.

Thermal efficiency: Range from 35% to 41% currently. Expected to go even higher.

Fuel consumption: 1050 to 1600 grams for a standard WBT of cold start plus simmer (respectably low).

Fuel types: TLUDs can utilize a wide variety of low-value chunky dry biomass fuels (e.g. corncobs, tree seed pods, nut shells), including briquette pieces that can be locally produced from unused biomass. “Stick-wood” is not a common TLUD fuel, but can be used vertically as “wood segments.” Vertical segments also with papyrus reeds, bamboo, etc.
Options: The Quad can be made as a TChar variation for ease of using the created charcoal as fuel in a charcoal stove or as biochar that is added to the soil.

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.

Grass Tablet Biochar
4 cm Grass Tablets
Household Grill modified with an iCan reactor

The grass tablet biochar (pyrolytic carbon) shown above was made in an iCan TLUD
with a variable speed blower. This charcoal was air quenched and is thus bone dry.
When wet, it is very soft and can be formed to fit a variety of shapes. I have found, for
example, that grass tablet biochar saturated with cold water is effective at reducing the
pain of burns.

The following pages illustrate some of the ways the above biochar was made.
Note: Grass biochar will be ashy as grass has considerably more ash content that
wood

Grass tablets broken into short sections prior to being loaded into the fuel chamber of
the iCan reactor.
These tablets were made from field grass about 3 years ago in Shelburne, VT. Note
that the longest fibers are about the length of the diameter of the tablet. Shorter is
better.
These tablets are about 4 cm in diameter.

VermiChar Eco-fertilizers subsistence Garden
VermiChar Eco-fertilizers Subsistence Gard

Attached are the trials i did with biochar from rice husks and vermicast. I mixed the two together and filled the containers to become my garden.

Some of the lessons i learned

1. vermicast is highly water soluble and quick releasing than compost. Therefore i had to sprinkle a scoop of the vermicast once every week.

2. The vermi cast - biochar mix need a curing time before it can support the plants. Beneficial microorganisms can help cure the mix.

3. The earthworms take up a considerable amount of nutrients from the compost to become their body tissues.

And then do you think we can use the biochar-vermicast mix into the floating gardens? They are much lighter.

Good luck with your project.

1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

For those interested in using coconut husk (not shell)
Unprocessed coconut hulls make lousy fuel.
Coconut hull fiber are generally know as coir.
http://en.wikipedia.org/wiki/Coir
It is a big business in India.
http://msme.gov.in/Chapter%206-Eng_200708.pdf
The fibers are processed into mats, carpet backing, potting material, and geotextiles (for erosion control).
On a small scale, the hulls can be soaked in water for at least a month and beaten to break the pith and used as mulch.
The pith leftover from fiber production is known as cocopeat.
http://en.wikipedia.org/wiki/Coco_peat
It is generally a coarse powder. It can apparently be made into fuel pellets for gasifier stoves. See attachments.

From Alexis Belonio:
Good morning!!

Attached are the info on the latest development on rice husk gas stove in India. Just to update you that rice husk gas stove is now being commercialized by Navdurga Metal Industries of India.

From the India Economic Times:

The three-year-old startup based at Faizabad in Uttar Pradesh has created rice husk-powered, smokeless biomass cooking stoves that significantly reduce the cost of household spending on conventional fuel sources such as LPG, electricity, kerosene, wood and wood charcoal. "Rice husks can give about 3,000 kilo calorie of energy, compared with wood that gives between 3,800 and 4,000. These stoves reduce carbon emissions, and cooking costs significantly," said Jaiswal, 31. Nav Durga's first product, aptly named Janta Chulha Smokeless Stove, was launched in 2009 and priced at Rs 500. It has now launched a range under the brand name, Agni, which caters to both domestic and industrial customers. "We currently manufacture up to domestic 10,000 cook stoves and about 50 commercial stoves a month. We want to ramp that up to 20,000 domestic and up to 1,000 commercial stoves soon," Jaiswal said.

According to recent industry data, about 67% of Indian households, adding up to about 166 million households, continue to use solid fuels as their primary source of cooking fuel. While conversion to modern fuels has accelerated in urban areas, rural areas have been slow. Saurabh and the firm's co-founder Arvind Jaiswal, 56, have set up their own distribution and supply chain system. The startup currently has about 50 distributors spread across Uttar Pradesh, Bihar, Assam and Punjab. The company employs about 50, spread across two facilities in Faizabad and Faridabad, in Haryana. "The manufacturing is done by local talent alone," Jaiswal said.

The original news article, and instructions sheets for the stoves are attached as pdf files.
