<div dir="ltr">Dear Nikhil,<div>producing biogas from dung is a very wasteful process. 1 kg (dry weight) of dung, which would yield 4000 kcal energy if burned, yields only about 200 kcal energy, if converted into biogas. In the city where I live, cowdung cakes are used in certain religious rites. They are sold at a lucrative price of about 9 USCents per piece. That would be a very attractive business for a Dutch dairy farmer, but drying the dung would be problematic in a country like holland. </div><div>Yours</div><div>A.D.Karve</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature">***<br>Dr. A.D.

Now all we need is for GACC to claim biogas as such superior clean cooking technology - Kirk Smith argued that in 2000 and I fully agree, just that there is too much open defecation by man and animal - that ISO must have lab testing at various scales. <br><br>Heck, I will even write the testing protocol and specify a standardized bull, a standardized meal, standardized poop, ... They have the rest - standardized water, standardized meals, standardized cooks. Just unstandardized dose-response claptrap. <br><br>Cow poop is ok, it is the Anthropocene bull manure that only a select few can digest, anaerobically of course. <br><br>"a small clay pisspot is a cutting-edge technology"? <br><br>Yeah, for the New Age nuevau riche of the New york times. <br><br>I once worked on a GHG offset project to both change cattle diet and to reduce methane emissions. If I remember correctly, open cow manure in hot areas dries up quickly and does not emit that much methane. <br><br>But those who want to cook up numbers and careers, research papers and propaganda, will stop at no BS. <br><br>Seriously, the main point here is that biomass is not a climate-friendly technology at all. Taken all the emissions from the production to consumption of foods - including those due to cutting forests, open burning of grass and leaves, forest fires - and valued in 20-year GWP terms, the contribution to atmospheric concentrations is much greater than that, say, from power generation. <br><br>Go read Nadine Unger. <br><br>Or Nick Stern, who I believe has gone veg. (I also hope he gave up sugar.) <br><br>Then again, there was some paper a few years ago claiming beef is a superior food because its carbon footprint can be quite low. <br><br>I prefer to be a horse. But I am fond of BS; academia and media give me such earthy fragrances all the time. <br><br>Nikhil<br><br><br>Message: 6<br>Date: Tue, 30 Aug 2016 10:41:04 +0530<br>From: nari phaltan <<a href="mailto:nariphaltan@gmail.com" target="_blank">nariphaltan@gmail.com</a>><br>To: Discussion of biomass cooking stoves<br> <<a href="mailto:stoves@lists.bioenergylists.org" target="_blank">stoves@lists.bioenergylists.o<wbr>rg</a>><br>Subject: [Stoves] Hi tech cow dung technology<br>Message-ID:<br> <<a href="mailto:CAGeG2tDBzt_RDONrSmo%2Bu-WTpcS9DsFSXUiDOa28cj1npWO5Jw@mail.gmail.com" target="_blank">CAGeG2tDBzt_RDONrSmo+u-WTpcS9<wbr>DsFSXUiDOa28cj1npWO5Jw@mail.gm<wbr>ail.com</a>><br>Content-Type: text/plain; charset=UTF-8<br><br>Hello stovers,<br><br>You might enjoy reading this article in NY Times.<br><a href="http://www.nytimes.com/2016/08/29/t-magazine/cow-poop-design-museum-castelbosco-farm.html?emc=eta1&_r=0" rel="noreferrer" target="_blank">http://www.nytimes.com/2016/08<wbr>/29/t-magazine/cow-poop-design<wbr>-museum-castelbosco-farm.html?<wbr>emc=eta1&_r=0</a><br><br>Cheers.<br><br>Anil K rajvanshi<br><br>--<br>Nimbkar Agricultural Research Institute (NARI)<br>Tambmal, Phaltan-Lonand Road<br>P.O.Box 44<br>Phaltan-415523, Maharashtra, India<br>Ph:91-2166-220945/222842<br><a href="mailto:e-mail%3Anariphaltan@gmail.com" target="_blank">e-mail:nariphaltan@gmail.com</a><br> <a href="mailto:nariphaltan@nariphaltan.org" target="_blank">nariphaltan@nariphaltan.org</a><br><br><a href="http://www.nariphaltan.org/" rel="noreferrer" target="_blank">http://www.nariphaltan.org</a><br><br><br><br>------------------------------<br><br><br> <br><br> </div>
