Good article written by Rev. J.D. Hooker. He shares his experience using manure as a fuel and the ash as fertilizer for the soil.

Making Manure BricksMaking Manure Bricks

Snip:
“It’s been well over a decade now since I first heard my friend Pete voice his amazement at my practice of spreading animal manure as a fertilizer. It seems that since time immemorial, well dried manure has been very highly regarded as a fuel in his homeland in the south of Thailand, with only the ashes left from burning the manure seeing regular use as a fertilizer.

Now Pete readily admits that he’s never had any experience with farming on the sort of huge scale regularly seen in our country. Still, he assures me that the yield routinely realized in their big market gardens very easily surpasses any that we’re used to seeing here. He’d never even heard of anyone ever needing to add lime to their soil, even though many of the gardens and small farms where he grew up have been in regular use for more than a thousand years.”

The Oxygen BombCalorimeter

Q.
I would like to know how the oxygen calorimeter works, if you don't mind.
Is it required that the sample be dried first?

If a wet sample was placed in the calorimeter with equivalent one gram
dry weight would the results be the same as a one gram dry sample? That
is, does the water in the sample lower the calorimeter value when measured?

Q.
Dear Stovers,
The fuel magazine that sticks out the side of a rocket stove is divided into two: above the shelf is where the fuel goes, and air passes under the shelf. Am I right in thinking that the fuel should be packed in as much as possible, to try and minimise the amount of air entering the stove through the fuel inlet? If so, why? My experience is that char builds up at the bottom of the elbow, so air is needed to burn the char (which in turn pyrolises the fuel), and a second air supply is required to burn the volatile gases. Any pointers would be warmly received.
Confused, Hugh.

Production of Sixbricks Rocket Stoves in Uganda and Darfur 2006
Ken Goyer, AidAfrica, International Lifeline Fund, November 12, 2006

Dear Tom,

I believe that so far, with Mathew and All Nations Christian Care, we have made about 15,000 SixBricks Rocket Stoves in the Lira, (north) Uganda refugee camps . I have 2,700 numbered pictures of these stoves, with the owner, her house, the flag of the Rotary Club of East Fresno and the number of the stove. Taking pictures has proven to be more difficult and more elusive than actually making the stoves. I hope to show these pictures at our ETHOS conference this year. Dan Wolf of the International Lifeline Fund has taken over this project in Lira and plans to fund 100,000 more stoves as well as to fund and run the project in Darfur camps to build a targeted 100,000 stoves there.

Meanwhile, I have started a new stove project in Gulu, (north) Uganda to make an unlimited number of Six Bricks Rocket Stoves in the Gulu refugee camps, in addition to teach stove building in Northern Uganda. AidAfrica is also working with Rotary Clubs in Southern Uganda to make about 1000 stoves for each of thirty Adopt a Village projects.

So this coming year will be even more exciting than last year.
AidAfrica now has an office and staff in Gulu and we plan to send volunteers from here to Gulu (and other parts of Uganda) to build stoves, start a reforestation project, address the problem of malaria and continue with the medical project which has directly saved very many lives.

Much thanks to you for running the stoves list. It has been instrumental to bringing the world closer together.

Best regards, Ken Goyer
