I bought one of your parabolic concentrators (from you in person) - I think in 2009 at that year’s ISES meeting in Johannesburg, A solar cooking friend recently took it to the ASES Headquarters in Boulder, as I moved to a smaller place..</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b. Not many on this list will know that you are exceedingly well known in solar cookers. I’ve added four (possibly mutual friends through SCI ) to add more on your own contributions over many years They all know the charcoal-making topics here</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>c. I had no idea you have been working on wood stoves - especially designs that could receive a parallel solar input.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>d. My own interests are now shifted from solar to biomass stoves - but always now with char-making as a carbon negative co-product. (Because char-using stoves have so badly ruined so many forests. - and must be phased out.)</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>e. This list has also recently been much more on char-making stoves than char-using or the “Ben” type you are working on. Maybe because they are new and still gaining converts and new ideas. For some reason, your contribution below is now quite rare on this list - unfortunately..</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>f. I think there is much less reason to run solar and char-making together, but urge char-making stoves as the backup when the sun is not available.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>g. I found some information on “Ben” at <a href="https://solarcooking.fandom.com/wiki/Dieter_Seifert" class="">https://solarcooking.fandom.com/wiki/Dieter_Seifert</a>. Please tell us of other sites. I’m sure the SCI site is better for solar cookers, but this list needs to learn more about solar cooking.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>h. I’d also like to discuss making char with solar concentrators. (probably troughs, but maybe not) I’ ve only seen that concept once in print. Cooking with the resulting syngas might offer some advantages in the solar cooking world. Can use the concentrator all day.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>i. Making char seems to me to be the most popular form of carbon dioxide removal (CDR) in general - not just in stoves. Because char is needed in soils.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>j. Kevin McLean is often now writing about a char-making stove that seems to be vary attractive to the many users of 3-stones - essentially zero cost. He uses “rods” some.</div><div class=""><br class=""></div><div class="">Ron</div><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jul 24, 2022, at 12:54 AM, Dr. Dieter Seifert <<a href="mailto:doseifert@googlemail.com" class="">doseifert@googlemail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><span style="font-size:12pt;line-height:107%" class="">Dear all,<span class=""></span></span></p><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><span style="font-size:12pt;line-height:107%" class="">For simplifying
