Boiling Point 47: The Modernization of Small Business through the Ecostove in Nicaragua.
The EcoStove is an innovative woodstove which basically is a vented and insulated stove. The fire is entirely enclosed within the firebox (a ceramic elbow) which, in addition, is placed within a box of insulated material such as pumice rock. Above the fire there is a plancha (a large metal griddle) which is heated firstly by the flames and secondly by the hot gases (smoke) being circulated under the plancha.
