Its simply that if the ceiling of it were dome-shaped, it would tend to concentrate at least the infrared heat, back down into the center of the combustion chamber. </div><div>As a dome shape, it would also be structurally stronger and more durable because it inherently directs the upper body load - stove and pot-downward and inward -in compression- with more even heating and more direct expansion of the surface of the dome as ceiling.</div><div><br></div><div>I sketched up a simple generalised form sample ,as a screen shot and .skp file, if you want to build on it, below, </div><div><br></div><div>Keep up the good work. If you make a manual ald sell it online, I will be happy to refer others to you. We have our own hands full with finalisation of our MINI thresher chopper ( “molino ya mano”) manual which you and I spoke of earlier. We’re also getting ready for return to Nicaragua and very likely a TOT project emerging from the training we did last march. </div><div><br></div><div>Richard </div><div>Briquette serf</div><div><br></div><div>CC dome concept for your stove</div><div> cross section </div><div></div></div></body></html>
