I would ordinarily have added this to the garden & healing herbs section which now is a read only reference library with moved-to links and the actual threads have been moved to this section, so, am going to post here and hopefully get a link there (for reference). That was one of my favorite sections and those topics haven't been added to in quite a while so I'd like to get things going again even with the changes. I'll may edit this bit out later but for now thought a little explanation was in order.
Ken Goyer has passed away some years ago and I'd read about this many years ago in a newspaper article and I didn't want the information to get lost (with his passing) so I searched for it again and found a few things, like the pictures of his trip to Sudan which I found very interesting.

A tragedy of worldwide proportions is unfolding in the Sudan where two million people have fled from terror and violence and now live as refugees. Removed from their homes and their livelihood they now live in camps such as this one and are dependent on charity for their survival.

Almost all cooking takes place on a three stone open fire. This is very wasteful and
inefficient. The stove on the right burns charcoal. Charcoal is also wasteful and
inefficient.

Posted Image

Past efforts to introduce cooking stoves have not been successful.

Posted Image

Any cooking fuel that might have existed is long gone. Everyone must purchase or barter for fuel, or go great distances to obtain it.

Posted Image

Firewood and charcoal is trucked from the surrounding hinterlands and sold. If you have no money then you must trade something. Many people are forced to trade some of their food to get the fuel to cook what food remains.

Posted Image

The SixBricks Rocket stove uses half (or less) of the fuel of the open fire. Of this half, less than half of the smoke and emissions are created. This stove has been highly engineered and tested and is easy to make from inexpensive, locally mass produced bricks.

The success of the Six Bricks Rocket Stove depends on six special bricks. They are not ordinary bricks. They are lightweight and will float on water. These bricks act as
insulation to keep the fire very hot and efficient, and to keep the heat directed at the pot. They form the combustion chamber of the stove and are the big secret of the Rocket Stove. This brick, made in Turkey with the Sehan Adana Rotary Club, is held by Ken Goyer and Wilfred Pimentel.

Posted Image

The Six Bricks Rocket Stove should actually be called the eight bricks rocket stove.
While six bricks form the combustion chamber, two more bricks are used for the wood entrance or “elbow”. (Wood ashes will insulate the bottom of the stove).

Posted Image

Once the six bricks are wired together and the entrance is made from the other two bricks the stove is mudded in place to make it stronger and more stable. Vahid Jahangiri from the International Lifeline Fund demonstrates this stove at All Nations Christian Care in Lira, Uganda.

The valley of the giant kilns. There is no shortage of brickmaking capacity or ability or desire in Darfur.

Posted Image

Brick makers at work and at play.

Posted Image

After testing the clay/organic mixture for the bricks, the first Rocket Stove bricks are
made.

Posted Image

The test bricks are burned in this mini-kiln.

Posted Image

Our first batch of bricks has been successfully burned.

Posted Image

Before we can demonstrate the stove to the women, the men have come to pass their approval. They like it!

The next day our first demonstration takes place.

Posted Image

The women learn rapidly how to assemble the bricks.

Posted Image

Working in teams the stoves are quickly assembled.

Posted Image

Cooking asseeda, their staple food, on the Rocket Stove. Asseeda is corn meal that is
boiled and stirred to the consistency of thick mashed potatoes. This is eaten plain or with various “sauces” or side dishes of whatever else might be available (meat being the most luxurious sauce).

Posted Image

In another demonstration asseeda and various sauces and tea are prepared on the
SixBricks Rocket Stove.

Posted Image

Dan Wolf and VJ talk with the women about the stove and the future aspirations of the International Lifeline Fund to provide everyone in Darfur with their own SixBricks Rocket Stove.

Why Are These Women Carrying Stoves On Their Heads?

Goyer came up with a stove constructed of six trapezoidal bricks that stand on end and are then wired together and encased in mud.
-----
The wood fuel is placed on a shelf in a hole in the front of the stove, which allows air to pass underneath and mix with the wood in an extremely hot combustion chamber. That allows the wood to burn more efficiently - no small accomplishment in lands where fuel is so scarce that people dig up dry roots to burn - and with less pollution.
-----
The secret of Goyer's design is that the bricks - clay mixed with finely ground rice husks, peanut shells, sawdust or other material - are light enough to float in water. The lightweight "aerated" bricks offer excellent insulation.
http://www.thefreelibrary.com/FUELED+by+a+desire+TO+HELP.-a0141059973
I'd like to figure out the shelf mentioned here. By appearances the stove is constructed like an igloo where the entrance is (for wood on the stove). I haven't seen any detail about a shelf under which air can pass other than this reference.
Also, I wonder where rice hulls and peanut shells might be acquired and what is used to fine grind them.
I wonder if this "aerated" clay that makes the finished product lightweight and a good insulator could be used successfully for the Zeer Pot-in-Pot Refrigerator. Lightweight is the way to go if it's doable.

In the years since, he has overseen the construction of literally thousands of stoves in El Salvador, Guatemala, Mexico, Turkey, Uganda - and now, Sudan. For years, Goyer worked strictly with other nonprofit agencies, but more recently established his own agency, Aid Africa, in hopes of better negotiating red tape.
-----
Goyer had to wait 11 days between sending two e-mails to his brother, who then passes them along to other friends and family. "He was more or less MIA there for awhile," said Warren Goyer.
Ken Goyer's e-mail spells out some of the pitfalls surrounding him.
"Sixteen vehicles have been stolen from (nonprofit agencies) - the Toyota Land Cruiser being the vehicle of choice," he writes. "One driver is still missing. These land cruisers will presumably be used by the rebels to eventually mount an attack - somewhere, on something and somebody. Much information travels by rumor."
