[Stoves] FW: Improved cook stoves and carbon footprint

[Crispin Pemberton-Pigott]

Dear Martha

ProBEC (Programme for Basic Energy Conservation - a SADC/GTZ project) has
some fairly detailed figures on the offshoot of those technologies which is
being implemented in Lesotho as the Tau Stove. This is a localised version
of the Libhubesi or Lion Stove. It retain some of the features of the Rocket
Stove upon which it is based but introduces another approach to combustion.
The final results, in terms of emissions and fuel consumption can be taken
to be very similar.

We are presently building 500 of these in Highland and Foothills schools
together with the WFP in Lesotho, financed by carbon so there is quite a bit
of information on the baseline, the savings (which have to be asserted then
proven) and carbon issues. 

With respect to 'GHG' you might find something missing depending on what you
want to know. Are you looking for a methane balance/offset or particulate
emissions (which are a significant air-warmer during the particulate's
lifetime)? How inclusive is your 'GHG'?

I'm lurking on this list in order to learn and also as research for a
writing project. Can anyone direct me toward information regarding
greenhouse gas emissions from stoves such as Peter Scott's Eco-Stove
and the "Sunken Pot Apro-stove"? I am trying to come up with plausible
comparative figures for biomass cooking and heating vs. electric
appliances powered by coal-generated electricity vs. natural gas vs.
LPG.

If anything has been published on this topic I'd appreciate being
pointed in the right direction. If not, informed opinions are welcome.
