[Stoves] planting trees ( the way I'd do it 1, 000, 000, 000 years from now)

Dear AD

 

Thanks. Regarding other users running off with the technology, Cecil Cook
found that there are about 3-4000 copies of my Terrabric Machine in the area
of Mthatha in the Eastern Cape of South Africa. The technology has gone wild
and it has displaced the hollow cement block as the dominant low cost
housing technology in the area. Something like 70% of self-built housing is
using stabilised soil bricks made (mostly) by women's groups.

 

Cecil and I introduced the technology in 1983 through an organisation known
as TATU. The bricks are now called 'tatu bricks' though no one remembers why
anymore. Heh heh. Another technology that went will was the jackal netting
machine operated by hand. That is a fence product also known further north
as 'pig wire' meaning it is used mostly got keeping animals out of vegetable
gardens.

 

I am glad to hear that your kiln design is running wild. It is a sign that
the technology is appropriate to the task at hand.

 

Regards

Crispin

 

 

Dear Crispin,

a cooperative started by our group is today the only organisation engaged in
making charcoal from sugarcane leaves. It costs about US Cents 25 per kg to
make the final product (briquettes) and we sell the briquettes at USCents 50
per kg to users of our Sarai cooker. About 100 organisations have purchased
our kilns. They do not char sugarcane leaves, but pine needles, needles of
Casuarina, urban leaf litter, grass, leaves and weeds found by the roadside
and light agricultural waste. Since the technology has not been patented,
there is also a likelihood that more persons are using it without our
knowledge. I know of at least one group in Germany, who have been supplied
with our kiln.

Yours

A.D.Karve
