[Stoves] ***SPAM*** RE: [SPAM] Rotary project question

[Willem Boers]

Dear Paul,

 

Innovations are always welcome and need to be assessed! 

 

The size of the cooking pot seems rather small. What is the typical pot size required in Uganda. In Rwanda a typical school needs pot size 100- 500 litres.

 

The stove should be tested for TE, and emissions as was done with Institutional Stoves in Rwanda. Only then can we compare. 

 

The CAPEX are very high, what makes the stove so expensive? , From the YouTube video I could not detect any expensive material or piece or equipment. 

 

 

With kind regards,

 

Willem

Subject: [SPAM] [Stoves] Rotary project question

 

I received this from a friend and would appreciate your comments:

"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%.   https://www.youtube.com/watch?v=4SyWCc-EGis.  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?"
