Definition

Der CCAT rocket stove hat gesellschaftlich und ökologisch Unterstützungsleistungen für die große Bevölkerung in die Entwicklungsländer, welcher haben keine Alternative als die Biomasse für ihre Kochenbedarf und Wärmenbedarf brennen. Die Agrargemeinwesenen weltweit von das Drei-Steine-Feuer für ihre Kochenbedarf abhängen. Unpraktisch Kochmethoden die Umwelt gefährden, zuviel Ernten des Kochenbrennstoff die Vegetation und Tiren beschädigen können. Das Verständnis der Kochenmethoden warum improved cook stoves sind ein bedeutend appropriate technology aufklären können. "Most cooking fires are surrounded by three of more stones, bricks, mounds of mud of lumps of fireproof material – thus the common name of three rock fire" [1]

Die Leistungen

Das Drei-Steine-Feuer hat die Leistungen dass modern Herd hat nichts: das Erwärmen (heating), der Insektschutz (insects), und das functionerit mit breitgefächert saisonbedingt Brennstoff können. Das Dre-Steine-Feuer erbringt die Beleuchtung wobei ein Herd erbringt nicht. "Three rock fires provide light, heat and a social focal point for family and friends."(Das Drei-Steine-Feuer erbringt die Beleuchtung, das Erwärmen und das Gesseligcenter für die Familie)[1] Ein Drei-Steine-Feuer in das Feuchtgebiet (wetland) kann der Insektenstich hindern, wenn es dichter Rauch macht. Das Feuer hat beträchtliche Vorteile gegen zu ein Herd. "It cost nothing and no special materials, tools or skills are needed to construct it"(Es costet nicht und benötigt keine Werkstofftechnik oder Fähigkeiten bauen).[1] Wenn die andere Funktionen des Drei-Steine-Feuer sind nicht nachbilden, dann der Herd ist nicht richtig bewertet. "If the fire is used to provide heat or light at times when cooking is not taking place, then its efficiency can hardly be judged only on the basis of how well it heats pots." (Wenn das Feuer bietet das Erwärmen oder die Leistungen wenn es kocht nicht, dann die Effektivität des Drei-Stein-Feuer nichts kann anhand von kochen abschätzen.)[1]

Die Kritik

Das Drei-Steine-Feuer wird von der Population der Entwicklungsländer dafür das Kochen abgehängt; aber die Gesundheit der Umwelt und der Leuten werden von dem Drei-Steine-Feuer gehindert. Zwei milliarden Leuten weltweit wenden die Biomasse dafür das Kochen und das Erwärmen an. Das altherkömmlich Drei-Steine-Feuer wird an den Irdenboden des Wohnsitz angewendet. Die Beeusstheit von der ökologisch und soziale Kosten hatte uber die lezten Dreizig jahren wachsen ("Over the last 30 years awareness of the environmental and social costs of using traditional fuels and stoves has grown.").[2]

Traditional three rock fires pose major obstacles to the environment, social health and sustainability of society. The most important concern with traditional three rock fires is indoor air quality. Biomass fuels release large amounts of air pollutants when burned on traditional three rock fires. These pollutants become concentrated in inadequately ventilated homes and dwellings. "Several recent studies have identified prolonged exposure to biomass smoke as a significant cause of human health problems." [3]

Biomass burned on three rock fires produces harmful soot and ash that become concentrated when confined inside a dwelling, resulting in harmful indoor air conditions. "According to recent estimates by the World Health Organization, up to 1.6 million women and children die every year from breathing polluted air in their homes." [4]

Respiratory and vision problems occur in mostly women and children because they spend significant time indoors tending to cooking fires. Another critique with traditional wood fires is the inefficiency in fuel consumption. Traditional wood fires are very efficient at turning wood into energy. However, traditional wood fires are inefficient at transferring the released energy into the cooking vessel. Most of the released energy in the wood is wasted heating the surrounding air rather than heating the cooking vessel. The inefficient transfer of energy requires the user to use more wood fuel, increasing the amount of wood harvested from the surrounding environment. The increased demand for wood can further deplete the already stressed local natural environment.

The third critique of traditional wood fires is childhood burns. "Burns are quite common in homes using fire and can be fatal or horribly disfiguring." [2] Children can easily fall into the fire because traditional wood fires are located on the floor. Burns disfigure and scar their victim and the experience can be very painful for the child.

    This publication addresses the very political nature of improved stove programs. The book informs the reader of: domestic fuels, current and past stove programs, and why improved stove programs should be used. The main advantage of this publication is the focus on stove programs success and failures and the books ability to refer to African societies past experiences with improved stove design. The books main disadvantage is the lack of any design or construction ideas for rocket stove design. Sections are included that refer to measuring efficiency and testing performance.

    This publication from the World Bank gives a comparison of stove programs throughout the third world. The paper gives an overview of the general lessons from stove programs: consumer preferences, stove design, role of government and donor agencies and the role of subsidies. The paper presents the role of politics in improved stove programs; considerable information regarding the emergence of government based stove programs is included in the paper. Advantages of included the stove market and consumer preferences section. This topic was not specificity addressed in any other publication. The main disadvantage of this publication is the role to the publisher. The World Bank has provided this paper with good intentions that must be questioned.
