Dear Friends,
A few weeks after Typhoon Bopha (locally Pablo) struck eastern Mindanao in December 2012, I was introduced electronically to a Filipina doing graduate studies in Saskatoon, Saskatchewan, Canada.. This young Filipina was fundraising for her home province of Davao Oriental in Vancouver but I was only able to contact her after she returned to Saskatoon. When she learned about the Eco-Kalan, she lamented at the thought of "so much rice donated to the typhoon victims but nothing to cook it with". Her lament has echoed in my mind ever since and has made me more determined to bring the Eco-Kalan stoves to victims of disasters wherever possible, not by ourselves, but with other organizations that can provide security, reliable transportation, food, drinking water, clothing and building supplies.

The stove was developed by Adrian Padt and Aidan Oosthuysen, and Richard Pocock, and uses a familiar Rocket design surrounded by a wire cage to improve the stove's stability and reduce burns. It's a smart looking stove, it saves women time and energy in gathering firewood, and it has lower emissions than the solutions it is typically replacing.

Lighting instructions:

The Rocket Works Stove, web site http://www.rocketworks.org/

  • The Rockt Works stove is a high efficiency wood burning stove, designed to accommodate multiple fuels when required.
  • It is smokeless after initial combustion, thereby reducing the likelihood of carbon monoxide poisoning and reducing the emission of black carbon particles.
  • The outer cage remains cool to touch even after hours of cooking, due to our innovative design.
  • It is made from high quality, heat resistant stainless steel allowing for years of regular use.
  • It can boil 5 liters of water in 15 minutes using as little as 250g of wood, which is significantly less than traditional cooking methods.
  • Its thermal efficiency is 45%, for the Large Pot High Power, performed by the SeTAR Thermal Efficiency Test.
  • Its emissions are the best in its class.

Basic Specification:

  • Mass: 2.95Kgs
  • Height: 270mm
  • Diameter : 240mm

Notes from Paul Anderson
Gustavo has presented a very nice video of the use of a tall TLUD gasifier under a DUAL purpose stove frame (frame = stove structure without the heat source) that first boiled 5 liters of water in 12 minutes, and then converted into a plancha stove with chimney, cooking papusas (related to tortillas). Total cooking time 1 hour 45 minutes on one batch of wood chips/chunks (5237 grams) that yielded 1300 g of char. 25% weight yield of char. Probably could have operated an additional 10 minutes with pyrolysis fire and a slightly lower percentage yield of char.

Note: That is approximately 4000 g of fuel of pyrolytic gases (including moisture content that was probably near 15%). Any ash content (probably 1% of the raw fuel) remained in the char.

For a comprehensive resource for TLUD stoves, see Paul's web site: http://www.drtlud.com/

Great half hour television program explaining Rice Hull Gasifier Stoves, and their potential in Vietnam.

It includes a good comparison of different stove types and designs, and interviews with people using the stoves.

Same video, the Vietnamese version:

Paal Wendelobo was an absolutely dedicated champion of clean cooking stoves, and the people that rely on them.

From his son:
"For almost 30 years, Paal brought attention to health and environmental issues connected to cooking and household energy for development countries. Paal found other people, later friends, with similar ideas and thoughts in this stove community. Despite arguments about stove design, function, and whom had the better stove. No doubt he was a pioneer, teacher but also he was a student."
"His simple Peko Pe stove invited people think new. He was also a pioneer of TLUD stoves."

He died with family a few days ago, and we'll miss him.

Christa Roth has updated the GIZ HERA Micro-gasification Manual
https://energypedia.info/wiki/File:Micro_Gasification_2.0_Cooking_with_g...

It is extensively revised, and features good -clear descriptions of essential cooking stove topics, e.g. choosing appropriate fuels, cooking stoves and technologies.

She highlights all of the major micro-gasifier cooking stoves, and includes a new section on biochar, with good, clear graphics and descriptions for how to use biochar.

An essential reference for everyone's cooking stove library, and this is all work supported by the German people through GiZ, we appreciate their support of Christa's amazing work.

PBS put together a nice video about the efforts to improve cooking stoves around the world:

There's more information on their web page: http://www.pbs.org/newshour/bb/building-cleaner-cookstoves/

Nancy Hughes and Gustavo Pena were highlighted with StoveTeam International. http://www.stoveteam.org/

Radha with the Global Alliance for Clean Cookstoves did a nice job outlining development challenges.

And there were a fair number of stoves that were included in the broadcast but not mentioned by name. I saw Envirofit, Burn Design Lab, Prakti and a few others represented. Let me know which ones I missed. :-) at erin@trmiles.com

Dear Friends,
On December 27-28, 2013, the Eco-Kalan Project Team led by Monica Sison and the Philippine Army (302nd Infantry Achiever Brigade in Tanjay, Negros Or.; 303rd Infantry Brigade in Murcia, Negros Occ,; and 62nd Infantry Battalion in Sagay) went on a relief mission to Purok San Pedro Beach in Barangay Old Sagay, Negros Occidental, Philippines*:

a) to distribute relief food supplies and clothing collected by Monica from a Catholic school where she is teaching, the Social Action Team of the Catholic Diocese of Dumaguete, and ONCAN (Oriental Negros Children Advocacy Network); and

b) to train 150 persons in the set up and use of the eco-Kalan from Barangay Old Sagay who were worst hit by Typhoon Haiyan (locally called Yolanda). These trainees would become the demonstrators at eco-Kalan presentations in their barangay in the New Year. Of the 150 persons selected by Barangay Old Sagay officials, only 35 were from Purok San Pedro Beach.

Purok San Pedro Beach is a coastal village where fishing is the main livelihood. It is also the poorest of the typhoon devastated areas in Old Sagay. Since Typhoon Haiyan (Yolanda) hit the eastern Visayas on November 8, 2013, little aid has reached this purok. The typical relief food package given to a family was 3kg of rice, 2-3 little cans of sardines and 2-3 packs of noodle soup -- a single day's meager provision for a family of 2 adults and 4 little children. Poor families extended the number of days they ate from this food aid by cooking the rice as lugaw -- i.e., rice boiled in lots of water.

There are some wonderful comprehensive overviews of clean cooking stoves on the internet.
These are a few great resources.

Dear Friends,

A few weeks after Typhoon Bopha (locally Pablo) struck eastern Mindanao in December 2012, I was introduced electronically to a young Filipina doing graduate studies in Saskatoon, Saskatchewan, Canada. She was fundraising for her home province of Davao Oriental in Vancouver but I was only able to contact her after she returned to Saskatoon. When she learned about the Eco-Kalan, she lamented at the thought of "so much rice donated to the typhoon victims but nothing to cook it with". Her lament has echoed in my mind ever since and it has made me more determined to bring the Eco-Kalan stoves to victims of disasters wherever possible, not by ourselves, but with other organizations that can provide security, reliable transportation, food, drinking water, clothing and building supplies.

When Typhoon Haiyan (or Yolanda) made landfall on Leyte on November 8, 2013, we immediately advised the Emergency Response Team at the Negros Oriental Governor's Office; the Department of Social Welfare and Development in Dumaguete; and our main partner, the 302nd Infantry Brigade of the Philippine Army, of the Eco-Kalan Project's interest to join relief missions to typhoon ravaged communities. Tacloban, Leyte and the northern islands of Cebu were quickly saturated with NGOs and security became a problem so our Project accepted the assignment to Cadiz and Sagay on northern Negros Island where little or no aid had been received. The Eco-Kalan team met with local barangay officials for Cadiz Viejo and Lacawon Island and for Old Sagay to assess the needs there and took photos for documentation (see links below). We also made plans for an Eco-Kalan demonstration and distribution of relief food and clothing in Cadiz Viejo for Lacawon and Cadiz typhoon victims on December 7; and later on December 28 for Old Sagay victims to allow time for the reconstruction of a covered area on a school ground. At each Eco-Kalan demonstration, an Emergency Eco-Kalan-C Kitchen is set-up with 10 stoves each.; and 150 householders are trained in the set-up and use of the Eco-Kalan (see demonstration photos below). These trainees will be the demonstrators at the Eco-Kalan presentations on January 11, 2014 for 670 households from Lacawon Island and Cadiz Viejo; and on January 25 for the 500 or more of the 2,082 affected households in Old Sagay, depending on donations we receive. Lacawon Island will be given 5 Eco-Kalan-C to set-up an Emergency Kitchen of their own. The Emergency Eco-Kalan-C Kitchen is an essential and necessary component of our demonstrations and presentations as nothing appeals more to the poor and hungry than the delicious aroma of the food we cook on the stove they are given.
