My questions on this particular stove:</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>a. What char yield is obtained? 25% possible?</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b. Can you supply the dimensions for the components. (Diameters and heights). A sketch would help (wanting to see both primary and secondary ari flows)</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>c. Of particular interest is your use of a skirt - which we don’t see enough of. How important for efficiency gain?</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>d. Is there primary air control? Might the primary air receive preheating?</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>e. This looks like you must be cooking for better than free - zero cost fuel and a salable (biochar) product. Can you estimate the months of operation to pay off the cost of the steel parts? (Over a 3-stone fire competition).</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>f. Has anyone done a simple water boiling test? Might you be at Tier five?</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>g. Is anyone making these for sale and at what price?
