Kevin, find a definition attempt on https://energypedia.info/wiki/Improved_Cookstoves_–_What_is_it_all_about%3F it is a bit more specific than merriam-webster. # Unfortunately, when I went there, the page is "under construction.' Would you agree with the following: What is a stove? The term ‘stove’ refers to a device that generates heat from an energy carrier and makes that heat available for the intended use in a specific application. # I think this is a good "broad definition" for a stove. However, it would, for example, also apply to a device that is more typically called a "boiler." In line with the Stoves Site, I was hoping to get a definition that was more restricted to Domestic or Residential cooking and space heating. Cook stoves are made to transfer the generated heat to food, with the purpose to get it cooked and edible for human consumption. Thus ‘a stove’ features the combination of heat generation and heat transfer to a cooking pot if the food is cooked in a liquid, or a griddle, plancha etc. if the food is baked on a hot surface or roasted without liquid. # Efficiency of heat transfer is indeed very important A stove can be designed to accomodate a pot on the surface, a pot submerged within the stove, a 'two pot system", open flame grilling, a grill or griddle where food is baked or fried directly on teh stove top, where no pot is involved, etc. While a stove can be designed for maximum heat transfer to teh pot, there are many "legitimate stove designs" where the manufacturer has no control over heat transfer to the food or pot. I would suggest that "stoves are made to provide an opportunity for heat transfer to food, but it is up to the user in many cases to employ a suitable pot, wind screen, convection shield, to maximize heat transfer to the pot or food." Indeed teh Customer may want a stove with lower heat transfer heat efficiency for convenience, and may specifically want a "flat top stove", rather than a "submerged pot stove", simply because of a concern for the outside of teh pot becoming sooty. However, the Stove Designer may decide to offer a stove broviding direct heating of the pot, to serve markets wanting such a stove. Expressed differently, he may offer some designs that attempt to maximize fuel utilization efficiency to sell into rthat market, and other designs, of lesser heat transfer efficiency, to provide the Customer with other wanted features. # Note also that stoves intended for Tropic Regions may not want any shell loss from the stove, while in temperate or cool regions, heat loss from the cooking stove can be a decided advantage. I feel we should also include a "space heating function" in the general definition of a stove. Clearly "heat loss from a stove shell" in areas where the warmth is wanted should be included as an "efficiency bonus" to the stove, but if teh same stove was used in teh tropics, where the "heat loss was not welcomed', then it should be treated as a "Fuel efficiency loss."

I would suggest that it is important that we all know what a "stove" is, when we attempt to determine the difference between a "good stove" and a "poor stove.' When we ask Mr. Google, we get more than 7 million hits. However, the most common definitions seem to be typified by the one at http://www.merriam-webster.com/dictionary/stove " 1a : a portable or fixed apparatus that burns fuel or uses electricity to provide heat (as for cooking or heating) " At http://stoves.bioenergylists.org/ , the stated purpose of the site is: "Our site is dedicated to helping people develop better stoves for cooking with biomass fuels in developing regions. " What about accepting the Merriam-Webster definition for a "stove?" Would anyone have a better definition for a "stove?"
