The data should be accumulated and published or simply noised abroad. Recent developments in biomass gasification, charcoal and coal burning stoves have changed the numbers pretty dramatically.<o:p></o:p></p><p class=MsoNormal>There are many very useful charts in Appendix 1 so I again recommend a read of this comprehensive review of improved stoves and the environments into which they are sold.<o:p></o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Crispin<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
