Kevin:
I think we all know what Aron meant in asking about a biochar stove. His first message, responded to by Erin, was very clear. You are creating considerable confusion with two comments I respond to below.

Dear Ron

# A "char making stove" is only relevant in a case where the person
wants a cooking/heating function, and ending up with a charcoal
residue is acceptable or desirable. In many cases, the production of
residual charcoal is undesirable.
# There is a lot of confusion with the term "biochar stove."
1: It is not possible to have a "biochar stove." One can certainly
have a stove that produces "charcoal", but charcoal only becomes
"biochar" when it is used in an agricultural application . A TLUD stove
is not a "biochar stove"... it is a stove that produces charcoal that
may or may not end up being used as biochar.
2: In that we have a "wood stove", a "kerosene stove", a "charcoal
stove", etc, the term "biochar stove" could simply be a stove that is
fueled with char, charcoal, biochar , etc.
[RWL: You (correctly) denied this sentence 's validity with your above ( now-underlined, italicized and bolded ) phrase. Fueling a stove with biochar is not an "agricultural application". .
# Is Aron perhaps designing a stove that is fueled with charcoal?
[RWL: Obviously not - see his first message (below) to the list. I wish that whole topic could disappear from this list - as it is usually so wasteful of biomass. Ron]
