[Stoves] FW: Need designs

Sun Sep 16 17:27:01 CDT 2012

So there's a new group people looking for stove designs that have mainly been visiting the web site so far.  They have learned a little about biochar, and they are interested in it, but they haven't really figured out how it works. They like the idea of a cooking stove and they are trying to make a biochar making cooking stove that they can use in their own community. They are brand new stove enthusiasts, and with a little help from us, they can do a good job making efficient stoves.

  I'm working hard to try to meet the needs to this type of stove designer because I think it's a great way to share the wealth of information and experience we have and foster a new generation of stove users and creators. 

To sum up, they are new and they are looking for 'biochar stoves,' and I think they've gone ahead and aptly named a class of stoves that will use fuel efficiently, hopefully emit less, and produce a helpful byproduct.  I generally tell them how wonderful and helpful you all are before I direct them to the list.  :-) 

Cheers,
Erin

 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

Quoting rongretlarson at comcast.net:

# 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]
