A stove adapted by the International Rice Research Institute (IRRI) from a Vietnamese design not only cooks rice more quickly, it is also environmentally-friendly and uses virtually free fuel. The stove called the Ipa-Qalan, uses rice hull waste and requires 1-1.5kg of the waste for one hour of cooking. The stove is easy to fire, has a low smoke level and needs minimal attention. It only takes 7am of newspaper to start and within five minutes can boil a litre of water. The design of the stove is simple, and it can be constructed economically from local materials such as recycled oil drums, biscuit cans and used sheet metal, using only a tin cutter, a hammer and a 4-inch nail. IRRI engineers have calculated that by using rice hulls instead of wood to fuel a stove, a household of five or six people could save at least two tons of wood each year; or about 1 hectare of a forest where trees are harvested for fuel. Rice hulls which are a byproduct of rice production, are often considered a nuisance and previously their disposal has posed problems as there have been few uses for them in most rice producing areas. As around 20% of harvested rice is composed of hulls, this is a large fuel resource. Previously, rice hulls have been largely ignored as a domestic cooking fuel because they are difficult to burn and are bulky. Additionally, traditional stoves burning rice hulls have generated too much smoke and required constant attention. The Ipa-Qalan design has overcome these defects.
