<p>I received this from a friend and would appreciate your comments:<br>

<p>"<span style="mso-fareast-language:EN-US" lang="EN-US">I received
the email below from a Rotary member in Ithaca New York. 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

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></p>
