Dear cookstove community,

Our friend and mentor, Dr. Larry Winiarski, passed away at his home in Oregon on August 5th at the age of 81. Inventor of the rocket stove and grandfather of the clean cooking movement, Larry was a true humanitarian and wonderful teacher in all things related to clean and efficient combustion and appropriate technology.

A memorial is planned for Saturday August 28th at 1:30 pacific time both in person in Oregon and on zoom. The invitation is attached and zoom link is here: https://oregonstate.zoom.us/s/91634829672?pwd=NlpBQTdxbGtpdUhWOGI3T1g3Y1....

All,

Attached are some drawings of a stove I have been working on. I hope at least some of you will enjoy looking through it. My design concepts are a bit odd, but they work.

A new handbook aims to help designers and entrepreneurs by translating recent R&D advances into practical approaches for improving biomass cookstove performance, usability and affordability. The Handbook for Biomass Cookstove Research, Design, and Development, was developed in partnership with MIT’s D-Lab and the Global Alliance for Clean Cookstoves, with funding by UK aid from the UK government.

Modifying a Retail Chinese TLUD Camp Stove for Improved Efficiency

The problem with the stove is that the primary air grate has large diamond shaped cuts for air. This allows the stove to burn excessively, producing a large flame exiting the stove top. The large flames envelope the pot bottom and sides producing heavy deposits of soot on the cooking utensil.

My idea was to modify the stove by reducing the primary air and attempt to force the flames back into the burner by using a stainless steel cylinder in the center of the stove opening to restrict the exiting air flow, and at the same time introducing air into the stove top by punching holes in the angled concentrator ring/pot support.

To restrict the primary air flow, a paint can lid was placed upside down inside the stove bottom. A threaded bolt was run through the center of the lid, and four small holes were punched for primary air. A stainless steel cylinder was affixed to the top of the threaded bolt. Cylinder height adjustments can be performed by loosening the jam nuts, repositioning, and re securing.

No fan is used.

The assembly is placed inside the stove, and wood pellets are poured onto the paint can lid. (About 1” deep). After the pellets are ignited, it takes around 5 minutes for the stove to gasify. After gasification, you can see the flames are being pushed down into the stove.

The PROFOGONES Project, created by Fundación Vida, is dedicated to promoting and developing the market for improved cooking stoves in Honduras.

Their website (in Spanish) is still under development, but they already have some excellent promotional and informational videos online:

I have built the ELSA stove that's
documented here, https://www.youtube.com/watch?v=55r5DmvT3XE .

I started with a stainless steel trashcan that had seen better days. I
unrolled it and glued on ELSA stove blueprints from the web. Then I cut out
the shapes with a 24 tpi bimetal blade in a jigsaw.

I don't have an anvil, or the sheet-metal "curling" tool (is there a name
for it?) that is shown in the video. I bent the metal over some angle-iron,
and I made the tool from some stainless tubing I bought at the hardware
store.

I couldn't get the stove to light until I used the lighting cylinder, which
is shown in the video, for some extra draft. I used brown packing paper as
tinder, and wood pellets as fuel.

Small scale biochar production and use was discussed at the annual conference of the Engineers in Technical and Humanitarian Opportunities of Service (www.ethoscon.com)

An estimated 2.5 billion people worldwide cook their meals with biomass. ETHOS is an international group of individuals and organizations that promote improved cooking stoves for health, safety, and household energy. The Toplit Updraft or TLUD stoves are efficient and can produce biochar as a co-product of household energy.

Participants were interested in how biochars can be used to remediate soils and improve agriculture. Norman Baker, Sequim, showed how a 55 gallon TLUD can be used to make biochar for growing vegetables and improving nutrition. Paul Anderson (drtlud.com) described 12,000 TLUD stoves in India that product 10 tons of biochar each day. Users receive cash from selling the biochar to a German company, atmosfair gGmbH, which recovers carbon offsets for the energy savings and char to help fund the energy efficient cooking stoves. Art Donnelly, Seachar (seachar.org) demonstrated a new biochar making stove and described how biochar from cooking stoves has been used by coffee workers in Costa Rica. ETHOS participants are among the 1600 partners of the Global Alliance for Clean Cookstoves (cleancookstoves.org)
