[Stoves] Advancement of "better" stoves

Design stoves that are functional, safe and efficient. And don't forget, to
design stoves that can be situated in modern kitchens. Getting rich people
in developed countries to use biomass stoves should be one of our big
priorities. I think that many of us grossly underestimate the power of the
tlud concept. Imagine a small tlud less than 10 inches in height; made of
high quality, long-lasting stainless steel; holding no more than about
three or four cups of wood or straw pellets; capable of putting out 2 to 3
kW of heat over enough time to cook an average meal; elegantly contoured to
match in beauty high-end kitchen accessories. Such a stove need not cost
more than $50 US to fabricate. It would produce a beautiful blue flame that
would rival that of a bottled gas stove. It would produce a valuable
biochar for farms and gardens. It would be proudly used in London or Laos,
Boston or Bangladesh. It would appeal to rich and poor alike.

Of course we can build cheap, tin can stoves. But why should we expect poor
people to use them, while we would never dream of doing so, except,
perhaps, on an occasional camping trip?
