I know of no way that you can <br>> turn a rocket stove into a char-making stove (but would love to hear <br>> differently).<br><br># A "char making stove" is only relevant in a case where the person <br>wants a cooking/heating function, and ending up with a charcoal <br>residue is acceptable or desirable. In many cases, the production of <br>residual charcoal is undesirable.<br><br># There is a lot of confusion with the term "biochar stove."<br>1: It is not possible to have a "biochar stove." One can certainly <br>have a stove that produces "charcoal", but<i><u><b> charcoal only becomes <br>"biochar" when it is used in an agricultural application</b></u></i>. A TLUD stove <br>is not a "biochar stove"... it is a stove that produces charcoal that <br>may or may not end up being used as biochar.<br>2: In that we have a "wood stove", a "kerosene stove", a "charcoal <br>stove", etc, the term "biochar stove" could simply be a stove that is <br>fueled with char, charcoal, <i><b><u>biochar</u></b></i>, etc.<br> <b>[RWL: You (correctly) denied this sentence</b>'s validity with your above (<u><i><b>now-underlined, italicized and bolded</b></i></u>) phrase. Fueling a stove with biochar is not an <i><u><b>"agricultural application".</b></u></i>.<br><br># Is Aron perhaps designing a stove that is fueled with charcoal?<br> <b>[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.
