[Stoves] Cuber and size of densifying machines. (no longer Re: The wood and char and fuel "debate" )

[Richard Stanley]

Crispin, 
The feel of the dung floor underfoot was comfortable as well. BAsed on the good ayruvedic advice there, we even smeared it on our 
peace corps earned bug bites in Ambepussa Sri lanka (mattha). 

It was actually neutral to bugs on the walls as well. Lets pitch it to the likes of Sadolins Sherman williams Pittsburg paints etc etc.
CAn you see the advertising copy;
the classic happy family smiling inside their new house in the burbs in background:  
  "Make your life better with cow shit..and it costs not on wit"

returning to topic…
we think that we have discovered something called the rocket stove when if you really think about it: We are not all that unique: 
 a good three stone fire with flat insulative stone surfaces reflecting heat inward and a large pot on top,  forms a kind of side feed port, 
and the cook periodically more or less continuously feeding in fresh  fuel supply through same port…
Hmm…  Who knows what when, eh ?

As I read the booklet at the time, there was no attempt at all to sterilise
anything. They used the 'dung water' as it was.

The same approach is taken with smearing dung over mud walls to protect them
from rain. Also all floors in traditional structures in Swaziland (and
elsewhere I assume) have the same covering. It involves taking fresh dung,
mixing in some mud and plastering by hand over the floor and up the walls.
When dry it doesn't smell of anything.

The dung water-clay mix undergoes a chemical reaction I presume involves
acid which is known to harden clay. 

There is a commercial clay process during which hard clay is softened with
one additive (which makes it really soft), then mixed with ingredients for
various purposes, then hardened with (I think very dilute hydrochloric
acid).

The type of clay matters a lot but the guys found it in Uganda where the
pamphlet was written.
