Also take a look at
for other pictures of this type of stove.

Jed started with the Rok Oblak Holey Roket stove:

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 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.

Dr TLUD (Paul S. Anderson) would like to share recent documents about rice husk gasifier technology and its application from Alexis T. Belonio (Professor and Engineer) of the Center for Rice Husk Energy Technology (CRHET).

The first four documents describe stove developments through CRHET’s collaboration with fabrication shops. These stoves provide rural households and small cottage industries new options for clean cooking using agricultural wastes, like rice husks, as fuel.

The fifth document describes a rice husk gasifier plant which produces enough electricity for community street lighting. This plant was developed by Suki Trading Corporation in Lapu-Lapu City, Cebu, Philippines in collaboration with Kanvar Enterprises and the Center for Rice Husk Energy Technology (CRHET).

This paper (see attached) describes a continuous-flow rice husk gasifier (CFRHG) designed and developed for various thermal applications such as cooking, drying, kiln firing, baking, and others. The technology follows the principle of a moving-bed, down-draft reactor converting raw rice husks into combustible gases that is rich in carbon monoxide (CO) and hydrogen (H2).

Different sizes were built and tested in collaboration with the private sector both in the Philippines and in abroad. The gasifier units which were built, tested and evaluated have varying reactor diameter, ranging from 0.40 to 1.20 m with a corresponding power output of 35.7 to 321.2 kWt. The rice husk consumption rate for the different reactor diameters tested ranges from 19 to 169 kg per hour. The specific gasification rate of the gasifiers was found to operate well at 150 kg/hr-m2. The temperature of the gas leaving the reactor varies from 150° to 270°C for all the units tested. The flame temperature reaches as high as 400° to 800°C, depending on the size of the reactor. The bigger the size of the reactor diameter, the higher is the flame temperature. The parasite load varies from 4.2% for the smaller diameter reactor to 1.5% for the bigger model. Combustible gases are generated within 5 to 30 minutes for the different sizes tested. The heating value of the gas ranges from 1200 to 1400 kcal/m3. And, only one person is needed to operate the small gasifier and two persons are needed for the big gasifier model.

Results of the tests showed that the CFRHG is convenient to use and its operation is easily controlled with the use of gas valves. There is no smoke emitted during operation. Black carbon content and tar emissions were found to be very minimal. The char produced can be used for agricultural application and the ash produced can be used for the production of low-cost construction materials.

What is an eco-KALAN?

An eco-KALAN is a portable stove made of clay consisting of three components: the outer shell (kalan) on which the cooking pot sits; the inner chamber (rocket elbow) where the combustion takes place; and a shelf with air holes to hold the fuel. The space between the kalan and the combustion chamber is filled with wood ash for insulation.

This video demonstrates how to build an Eco- Magic Box; and how to use the Magic Box and the Commercial (C) Eco-Kalan in the Lunch Feeding Program at South City Central School in Mangnao, Dumaguete City, Negros Oriental, Philippines.

Avocado Eco-Kalan Presentation, February 19, 2010.
Avocado is a mountain community in the town of Sta. Catalina, Negros Oriental, Philippines. Donors from British Columbia, Canada are Kees & Rebecca Arrieta Vermeer and the Chilcotin Log Church. Avocado is unique in that it was and continues to be a base for insurgencies by the New People's Army.

The projects are supported by non-profit organizations in British Columbia, Canada.

Stove development has been in collaboration with Nate Johnson and Mark Bryden of Iowa State University and Sebastian Africano of Trees Water and People and Aprovecho Research Center.

An Update from BSH on Protos. The Plant Oil Stove.
Samuel N. Shiroff, Director, BSH

For a brief update BSH is preparing a mass production capacity that should come on-line in late autumn of this year. Initial production will be ramped up through Q4 so we can expect to produce several thousand units in 2009. We are working with a local Indonesian partner - in an OEM process with 100% local content. This is part of our goal, but since BSH is not present in any meaningful way in our conventional business in that country, it is a very new activity for us. Thus, the time line may be subject to delay if quality or other issues arise. I would rather delay a few weeks than deliver a defective product.

The initial cost is going to be around US$40 - 42 Ex-works. This means it does not include transport or tolls if moving outside of Indonesia. Our total capacity for 2010 should be around 50,000 units - so this price will hopefully edge down. Naturally currency fluctuations will also play a role. BSH is running the project as a "social business". This means our goal is simply to cover costs and any additional profit will be put back into the project - for instance subsidizing costs in countries where there is viability, but not enough purchasing power for the capital costs. The mentioned price is the cost of production and local overhead. No more. Larger orders do not generate greater discounts. At first all orders will be filled out of Indonesia. New production capacity requires a minimum annual demand of 25,000 units and a viable infrastructure in the desired region. With perhaps the exception of the tank and some cleaning tools, it is simply not possible to establish small-scale local production that ensures consistent quality in an economically viable manner.
