As for the burning of renewable biomass, again some Eurofreaks have said that the Dutch funding of improved stoves is not climate-focused because biomass is carbon-neutral. <br><br>Kirk Smith declared that "If one were to put carbon in the atmosphere anyway, CO2 is the least harmful from both the climate and health points of view." He meant the high GWP of biomass PICs, which in turn meant that not only was biomass as "traditionally" burned (unprocessed fuel, uncontrolled TSF) was NOT carbon neutral, LPG was superior from both GWP per meal and air pollution (however summed) per meal. <br><br>That gave him the courage and confidence to write <a href="http://www.kirkrsmith.org/publications/2002/12/06/in-praise-of-petroleum">In Praise of Petroleum</a> (2002) and later <a href="https://www.forbes.com/sites/realspin/2014/05/27/the-petroleum-product-that-can-save-millions-of-lives-each-year/#6d870a19769f">The Petroleum Product That Can Save Millions Of Lives Each Year</a> (2014), specifically for LPG. He had laid out the basic rationale for gas cooking in 1989, and rightly so. <br><br>Forget his assumptions for methodical killing and salvation of "millions"; he affirmed the hollowness of biomass argument of "renewability" or "carbon neutrality". <br><br>Not all fossil fuels are alike. And each can be used in a myriad of ways, with emissions vented or contained.<br><br>LPG is among the most versatile of fuels with the most varied applications in varied sizes. Probably the best. From power plants in Japan to lighting in Vanuatu to water heaters, cigarette lighters, fuel cells, space heaters, and refrigerators and chillers.<br><br>Because of this, I support area gasification as much as area electrification. Both gas and electricity can come from biomass; I don't care if it is locally renewable.<br><br>Nikhil<br><div dir="ltr"><br>On Nov 18, 2018, at 5:52 PM, Crispin Pemberton-Pigott <<a href="mailto:crispinpigott@outlook.com" target="_blank">crispinpigott@outlook.com</a>> wrote:<br><br></div><blockquote type="cite"><div dir="ltr">
