[Stoves] Report #1 from ETHOS meeting

Mon Jan 26 06:42:25 CST 2015

Dear Bodie

Please take these performance numbers with a grain of salt.

Three of the metrics have no physical basis in reality and several of the others are misleading. ‎ For the char making TLUD's the 'fuel consumption' metric is highly misleading to the tune of >200%.

Marc Park pointed out at ETHOS that in a village studied where all users had an 'improved stove and used them religiously' there was no net fuel saving.

Before using a performance metric for comparison check first if it is telling you what you think it is (or have been told it is).

Frankly, we don't really know how improved stoves compare in performance, for the most part. The ISO and the South-South Sustainable Stoves Group are both working on cleaning up this situation because it is wasting a lot of time, social capital and money.

Crispin

Wow! This is a great resource, Christa!

I'm really curious about the StoveTec TLUD -- does anyone know why it
had/has such incredible performance? And why is it not in production now
(as the document says)? I would love to know more about it.

Thanks!
Bodie

*Food for Thought:*
*"A mountain is composed of tiny grains of earth. The ocean is made up of
tiny drops of water. Even so, life is but an endless series of little
details, actions, speeches, and thoughts. And the consequences whether good
or bad of even the least of them are far-reaching."*
