She has put together an $11,620 project (attached) to pay for Vron Engineering of Kampala, Uganda, to build four fuel-efficient stoves at schools in Gulu, Uganda, enhanced with a PV-powered fan to regulate the cooking temperature. Vron Engineering claims their unit reduces firewood or charcoal use by 80%. <a href="https://www.youtube.com/watch?v=4SyWCc-EGis">https://www.youtube.com/watch?v=4SyWCc-EGis</a>. The Rotary presentation is very professional, but my unscientific mind is skeptical. I know that clean cookstoves reduce firewood use, but it seems doubtful that adding a PV panel, battery and fan would further reduce fuel use. And without the PV panel, it seems excessive to spend $11,000 to demonstrate that clean cookstoves (with stovepipes) actually save fuel—something everyone already knows. Your thoughts?"</span><o:p></o:p></p><p><span lang=EN-US style='mso-fareast-language:EN-US'>Paul Arveson</span><o:p></o:p></p></div></body></html>
