Your char/biiochar work is great.</div><div><span style="white-space:pre-wrap"> </span></div><div><span style="white-space:pre-wrap"> </span>Can you further clarify this last “excited’ sentence? That is - I am “excited" about <b><u>both </u></b>your char/biochar and Kevin’s char/biochar. I like Kevin’s because it uses (cooking) the energy that most 200 liter drum’s can’t. And for the multiple reasons I gave earlier today on why 3-stone fires remain so successful (zero cost, non-batch, less fuel preparation, etc.. Kevin could be making a major change in the way three-stone fires will be used - and his idea (and self-funding) is only a few weeks old. To the climate benefit of us all.</div></div></div></blockquote><div><br></div><div>IN A SENSE, I MUST AGREE. THE ENERGY CAPTURE ASPECT OF THE EMBERS APPROACH IS GREAT AND SOLVES THE BIGGEST PROBLEM WITH TLUDs, THE IMPOSSIBILITY OF MAKING USE OF THE HEAT PRODUCED UNDER ALL BUT THE RAREST OF CONDITIONS.</div><div><br></div><div>IN GENERAL, HOWEVER, I AM NOT BOWLED OVER. WHY? FIRST, IN MOST TRULY POOR AREAS, THINGS LIKE CORN COBS AND OTHER FUELS EASILY PYROLYZED IN A TLUD ARE SELDOM AVAILABLE. RATHER, MOST BIOCHAR IS MADE BY DIGGING A TRENCH IN THE GROUND TO PYROLYZE HAY, STALKS, STEMS, AND STRAW AS WELL AS HARD TO MANAGE STUFF LIKE BRANCHES AND BAMBOO THAT OTHERWISE REQUIRE A LOT OF ENERGY TO CUT TO SHAPE.</div><div><br></div><div>SECOND, WHAT IS EXCITING ABOUT WHAT I REFER TO AS BIOCHAR, THAT BASIC STUFF PRODUCED BETWEEN 450 AND 550 C IS THE NEAT ARRANGEMENT OF THE C INTO CIRCLES AND ALL THE REST THAT SEEM TO PROVIDE BIOCHAR MADE AT THIS TEMPERATURE ITS VERY LONG LASTING AND AMAZING SOIL ENHANCEMENT PROPERTIES. CONVERSELY, THE LOWER TEMPERATURE STUFF THAT CONTINUES TO CONTAIN LOTS OF AROMATICS DOES HAVE IMMEDIATE VIRTUES. MOST IMPORTANT, THESE "HUMICS" AS I BELIEVE THEY ARE CALLED. SPEED GERMINATION AND WHAT NOT FOR APPROXIMATELY A YEAR UNTIL THEY ARE EXHAUSTED. WHILE THIS IS PERFECT IF YOU ARE MAKING A FERTILIZER AND WANT REPEAT CUSTOMERS, IT IS NOT GOOD FOR USE IN GARDENS FOR THE LONG-TERM.</div><div><br></div><div>I HAVE NO IDEA ABOUT EMBER CHARS OTHER CAPABILITIES - ITS ABSORPTION AND ADSORPTION CAPACITIES THAT MAKE BIOCHAR SO VALUABLE IN THE FACE OF CLIMATE CHANGE AND IN POLLUTED SOILS. THESE, HOWEVER, FIGURE VERY IMPORTANTLY AMONG THE REASONS FOR WHICH I AM "EXCITED" BY WHAT I REFER TO AS "BIOCHAR" (TEMP RANGE SPECIFIED) AND WORRY THAT DEFLECTING EFFORTS TO TRAIN POOR FARMERS TO MAKE BIOCHAR FROM AVAILABLE AG WASTES THAT WILL OTHERWISE BE BURNED IN NOT A GOOD IDEA. ALL OF WHICH LEADS BACK TO MY FINAL QUESTION: "WHY ARE WE SO EXCITED ABOUT BIOCHAR WHEN THE ALTERNATIVE OF USING CHARCOAL IS SO CLOSE AT HAND?"</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="overflow-wrap: break-word;"><div dir="auto" style="overflow-wrap: break-word;"><div><br></div><div><span style="white-space:pre-wrap"> </span>4.
