The free pdf version is at: <a href="https://aip.scitation.org/doi/pdf/10.1063/1.5141191?class=pdf" class="">https://aip.scitation.org/doi/pdf/10.1063/1.5141191?class=pdf</a>.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>This is a nice stove-breakdown list - that they mostly cover:</div><div class=""><br class=""></div><div class="">(a) According to technology used: Traditional and Improved cookstove </div><div class="">(b) According to draft or air supply: Natural draft and Forced draft </div><div class="">(c) According to combustion mechanism: Direct combustion and Gasifier </div><div class="">(d) According to fuel used: wood, Dung cake, charcoal, residue crops, Multi-fuels </div><div class="">(e) According to material: Mud, Brick, Ceramic, Metal and Hybrid </div><div class="">(f) According to fuel feeding: Batch feeding or continuous feeding </div><div class="">(g) According to utility: Domestic size or Community size </div><div class="">(h) According to chimney used: Cookstove with chimney or cookstove without chimney </div><div class="">(i) According to portability: Portable or fixed type </div><div class="">(j) According to pot used: Single pot or multiple pots </div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>I would add one more:</div><div class="">k). According to money flow: Make money or spend money while cooking</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Obviously there should be some stove-user interest in money-making. The only way I am aware of is making charcoal. Others? </div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>So this k) option is already possible as a part of c) Gasifier (meaning only TLUD in this paper). But (unfortunately) not much of k) is now happening as part of c). Nor is marketing of char discussed in this article.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>But there are many ways to make charcoal and some of the other ways are potentially applicable to cooking tasks. I’m working on a message on these other non-TLUD ways - and would welcome on-list or off-list dialog if anyone else is doing that.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>If we discuss k) seriously, it seems that k) can involve EVERY one of the breakdowns a) through j). I am concentrating now on modifications of both the “Traditional” and “improved" parts of a). This category can also expand what is covered in a) through j). For instance, b) can include “no draft”. e) may have other options than those shown. f) might have “and” as well as “or”.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>This paper is a nice summary of much past work, but is essentially silent on k) - the making of char/money while cooking. No discussion of how char influences efficiency computation.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Thoughts?</div><div class=""><br class=""></div><div class="">Ron</div><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">Begin forwarded message:</div><br class="Apple-interchange-newline"><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;" class=""><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif; color:rgba(0, 0, 0, 1.0);" class=""><b class="">From: </b></span><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif;" class="">Google Scholar Alerts <<a href="mailto:scholaralerts-noreply@google.com" class="">scholaralerts-noreply@google.com</a>><br class=""></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;" class=""><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif; color:rgba(0, 0, 0, 1.0);" class=""><b class="">Subject: </b></span><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif;" class=""><b class="">"The effects of fuel type and stove design on ..." - new citations</b><br class=""></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;" class=""><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif; color:rgba(0, 0, 0, 1.0);" class=""><b class="">Date: </b></span><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif;" class="">December 24, 2019 at 6:47:33 AM MST<br class=""></span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;" class=""><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif; color:rgba(0, 0, 0, 1.0);" class=""><b class="">To: </b></span><span style="font-family: -webkit-system-font, Helvetica Neue, Helvetica, sans-serif;" class=""><a href="mailto:rongretlarson@comcast.net" class="">rongretlarson@comcast.net</a><br class=""></span></div><br class=""><div class=""><div style="font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration: none; font-family: arial, sans-serif; font-size: 13px; line-height: 16px; color: rgb(34, 34, 34); width: 556px; max-width: 600px;" class=""><h3 style="font-weight: normal; margin: 0px; font-size: 17px; line-height: 20px;" class=""><a href="http://scholar.google.com/scholar_url?url=https://aip.scitation.org/doi/abs/10.1063/1.5141191&hl=en&sa=X&d=17213963389128872961&scisig=AAGBfm0-waMeF4PChI8-x6xowjhFKrv5zg&nossl=1&oi=scholaralrt" class="gse_alrt_title" style="text-decoration: none; font-size: 17px; color: rgb(26, 13, 171);">Evolution of high performance and low emission biomass cookstoves-an overview</a></h3><div style="color: rgb(0, 102, 33);" class="">C Samal, PC Mishra, S Mukherjee, D Das - AIP Conference Proceedings, 2019</div><div class="gse_alrt_sni">As a huge rural population worldwide is depending on open-fired or traditional<span class="Apple-converted-space"> </span><br class="">cookstoves to meet daily domestic energy needs, improvement of thermal efficiency<span class="Apple-converted-space"> </span><br class="">and reduction of harmful emissions are essential.
