Dear all,

For over two years we have been telling people that in two weeks or so we hope to have the mud Rocket Stove website updated. It finally happened. Flip has worked countless hours on this. This morning she shouted out, "The baby is born!"

Thanks to Larry Winiarski for all the mentoring and watching over us. Without Larry and the Good Lord this would have never happened.

Happy New Year,
Jon and Flip

and the movie:

Flip and Jon Anderson put together a beautiful earthen oven that's powered by a Rocket stove. They've got all of the details on their picassa photo album:

They were inspired by Kiko Denzer's book Build your Own Earth Oven to build the supports with apple pruning into an inverted basket, and then mix the clay and straw to put over it. This was done on a wonderful earthenware support built on top of simple framing to elevate the oven to allow for the rocket stove underneath.

Larry Winiarski offered suggestions and tweaks to improved the efficiency of the stove, and Flip and Jon report that it makes a beautiful pan of rolls and marionberry pie, with very little wood, and can also boil water off the top of the chimney. Nicely done.

Kobus Venter put together a great article that helps define the Rocket Stove. Please take a look at it on his web site:

This is a Hybrid Combustion Rocket, TLUD stove designed for practical use with the help of Larry Winiarski, and with Gustavo Peña of Stove Team International.

The "Easy 5 Gallon Bucket Rocket Stove", is very easy to build. All materials anyone needs to cook a good hot meal is a metal 5 gallon bucket, some stove pipe and vermiculite, pearlite or similar insulation (even "wood ash" can be used). Since the insulation separates the heat from the housing, almost ALL of the flame and heat is directed up to the cooking pot or utensil. Almost NO heat is wasted, making it one of the most efficient rocket stoves I've seen. Definitely one one the EASIEST to build and transport!

Robert Lange, and the team from the ICSEE has been working in cooperation with the local Maasai leadership to bring both improved cookstoves and improved light and radio access to their people, as well as the training to install and repair their own stoves and PVC systems.

This project does a great job of teaching the women of the Maasai tribes to build their own improved rocket style stoves using local materials, and relatively small sections of steel and rebar to improve the durability of the local ceramic brick. The women are clearly proud of their new stoves, and their ability to repair, and move the stoves as needed, and even better than that - the neighbors are jealous and motivated to learn and build as well.

More information is available on their web site:

Dean Still, August 2010

One fine rainy morning two fine fellows from StrawJet ( , an Oregon company that makes equipment to bundle agricultural waste in Malawi, wandered into the lab and asked if it’s
possible to make a stove that uses bundled corn stalks to cook food. I said that I thought it was possible and after some conversation and testing of prototypes StrawJet put up a $250 prize to encourage Stove Camp participants to make it so.

Burning corn stalks leaves quite a bit of ash that does not fall apart but keeps its shape.
For this reason stoves must be adapted to deal with a lot of solid ash. Two types of stoves
were tested: 1.) A Jon Anderson Rocket Stove with lots of draft and a grate and 2.) Two
large TLUDs built by Paul Anderson and Art Donnelley that were vertically loaded.

Participants voted for the best stove that, in their opinion, was most effective. Jon
Anderson won the 2010 Cat Piss Award for a tall Rocket stove made entirely from found
materials that successfully burned the bundled corn stalks. The hope is that a pilot test
could be conducted in Malawi. If so, we’ll pass along the results.

Jon and his wife Flip have been in Haiti recently for three months helping folks to build
these kinds of Rocket stoves. They are beautiful, dedicated people, who like many folk at
Stove Camp, deserve real praise and adoration. I’m happy to send them some of both and
congratulations for making a wonderful stove!

Hola companeros,

Mandanadose un reporte algo grande, pero de interes sobre el trabajo que hice Rogerio y Winrock introduciendo una estufa tipo Justa pero modificado para Peru, la Inkawasi
