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:<br><br>Charcoal making stove:<br>
This is overall most efficient and cheapest in costs of money or materials I have came accross: <br><a href="http://holon.se/folke/carbon/simplechar/simplechar.shtml">http://holon.se/folke/carbon/simplechar/simplechar.shtml</a><br>
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.<br>
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.)<br>
<br>Stick burning stove:<br>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.<br>
<a href="http://www.mrhpngo.com/mud%20stove%203.jpg">http://www.mrhpngo.com/mud%20stove%203.jpg</a> <---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.<br>
<br>Other burning thing (zero material cost, work will cost some): <br>Stick burning movable clay stove with good circulation and insulation:<br><a href="http://koti.mbnet.fi/maxt/tempstuff/Clayfire/flamepot.gif">http://koti.mbnet.fi/maxt/tempstuff/Clayfire/flamepot.gif</a><br>

(N.E.R.D.-society stove, from Coimbatore University)<br>If and when such breaks down due to dropping or falling objects... at least it is not costy to replace.<br>And it has ready cooking places for different sized pots and pans :)<br>
