4. Conclusions
This type of stove has the potential to save fuel wood because it can work on a great variety of non-wood or waste-wood fuels. The combustion efficiency and heat-capture efficiency of stoves are better than efficiencies of open fires and stoves currently in use, resulting in the need for less fuel. There are millions of small and inefficient cooking fires needed to feed economically poor people. Society needs an efficient stove that does not pollute, and the small wood gas stove is one of these, and quite possibly the best of these.
