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/flamepot.gif http://koti.mbnet.fi/maxt/tempstuff/Clayfire/flamepan.gif 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 :) MaxT http://www.ymparistojakehitys.fi/energia_terrapreta_english.html On Wed, Nov 16, 2011 at 10:38 PM, Lina Lopez Ricaurte < [email protected]> wrote: > Hi everyone, > > I am a biologist from Colombia South America currently working in a > project to reduce mangrove wood consumption for cooking in a very isolated > place of my country called Golfo de Tribugá on the Pacific coast. > > One of the alternatives in which I am working at, is the installation of > efficient stoves. > I was wondering if someone could help me with some advices, models, > learned lessons, budgets etc. > > > Many thank! > > Lina Lopez Ricaurte > > _______________________________________________ > Stoves mailing list > > to Send a Message to the list, use the email address > [email protected] > > to UNSUBSCRIBE or Change your List Settings use the web page > > http://lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org > > for more Biomass Cooking Stoves, News and Information see our web site: > http://www.bioenergylists.org/ > > >
