| '''Cook stove''' is a general term for stoves used in developing countries, often of a very simple designs. Efforts have been made in recent years to design and promote more efficient stoves, known as ''improved stoves''', ''improved cookstoves''' or '''improved cook stoves''', that don't fill the home with harmful smoke (through more efficient burning to reduce smoke, and a chimney or venting to remove that smoke), and which use less fuel. Several designs have been developed.

| ==Ongoing research and development==
| |
| Groups including the [[Legacy Foundation]] and [[EWB San Francisco Professionals Chapter]] are doing research into optimizing such stoves, including using briquettes made from waste biomass (e.g. agricultural waste) with a simple [[briquette press].

| The fuel used can have a great impact on the smoke produced, as well as affecting the environmental impact. {{WP|Charcoal}} is much cleaner burning than wood or dung, but is usually made from wood.

| {{WP|Amy Smith}} has done work on producing charcoal from other forms of biomass. To make the biomass stick together, a binder is used. (Another method of making briquettes more cohesive is to leave the biomass in water for a couple of days to decompose slightly.) The choice of biomass depends on what is widely available, but includes {{WP|bagasse}} (sugar cane waste) bound with a paste of {{WP|cassava}} root (also called manioc or tapioca); and wheat or rice straw bound with a small amount of dung, in areas where pure dung is normally burnt.<ref>[http://youtube.com/watch?v=FwFkb1x7FJQ MIT's Amy Smith on third-world engineering: TEDTalks] - Video on YouTube.</ref>
