[Stoves] efficiente stoves in Colombia

[Max Turunen]

Some *no budget at all* effeicient stoves... for extreme (and fashionable
:) ) high tech of low tech, or for temporary stoves before more precisely
purpose selected stoves can be obtained:

Charcoal making stove:
This is overall most efficient and cheapest in costs of money or materials
I have came accross:
http://holon.se/folke/carbon/simplechar/simplechar.shtml
Uses any dry biomass, relatively little or no smoke at all... and as end
result it gives charcoal after cooking / water heating is done. Can be
safely used outdoors or in *very* well ventilated areas... not in ordinary
indoors.
That charcoal can be then mixed with wet compost to make Terra Preta -type
mixture for turning very poor earths into permanent sandy soils. (charcoal
is not same as ashes... just clarifying in case of language barrier.)

Stick burning stove:
For non charcoal making stoves that burn branches, most efficient in whole
life cycle costs seems to be... Suuxat Rao -mud stove. It's a solid moon
type crater made from clay/mud, with about 1/8th left open for adding wood
and air intake. Wood is burned in such angle that it is not touching the
bottom of the 'crater'. rims/walls of about 35-45cm high crater keep the
kettle / pan in place, but let air through at the edges of the pan.
Material costs are small, burning is efficient, but needs specific form of
biomass: branches, sticks, planks, such.
http://www.mrhpngo.com/mud%20stove%203.jpg <---kind of just like that. It's
important that air comes to burning part of sticks from below as that makes
efficient burning, reducing the amount of smoke.

Other burning thing (zero material cost, work will cost some):
Stick burning movable clay stove with good circulation and insulation:

http://koti.mbnet.fi/maxt/tempstuff/Clayfire/pot.gif
(N.E.R.D.-society stove, from Coimbatore University)
If and when such breaks down due to dropping or falling objects... at least
it is not costy to replace.
And it has ready cooking places for different sized pots and pans :)
