I am not advocating that they go further to find the wood, I am advocating that they raise their own energy - exactly as they raise their own food.

The energy gained by the pot (including the heat gained by the pot material as it can be substantial) is determined over a cooking simulation. In the case of the CSI-Indonesia pilot the determination is made using the CSI-WHT (‘Water Heating Test’). This is an accurate measure of the energy gained by the pot – to within a few Joules.</span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">Energy applied divided by energy drawn from the forest is the system efficiency, or ‘overall efficiency’.</span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">Regards</span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">Crispin</span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA" style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span lang="EN-CA"> <o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">Hi All,</span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">I found myself a little confused by the discussion. </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">Not being expert in the field, this is how I would pose my questions:</span><span lang="EN-CA"><o:p></o:p></span></div></div><ol start="1" type="1" style="margin-bottom: 0cm; margin-top: 0cm;"><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">There is a certain amount of energy per kilogram of wood (I’m going to stick with wood for the moment rather than all biomass).</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">When burned, some of that energy is realized and some is not, i.e. there is not complete combustion. How complete is the combustion? How much energy is released? That would be the first measure. I want this because it tells me about one component of the system and is useful for design. It does not tell me the net result for the user.</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">How much of the released energy goes into cooking? That would be my next measure. That should tell me what weight of wood people have to collect to cook their food. It is worth noting that the amount of energy that goes into cooking is also affected by the pots and lids used as well as how they fit onto the stove.</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">It is also important to know how much energy was expended to get the fuel and prepare it for use. Some of that energy is human energy so it gets treated a bit differently and has a different impact. For example, it doesn’t convert simply to climate impact (are humans low global warming gas emitters?). If you cut up the fuel a lot and process it a lot there is a cost there. I don’t know how that stacks up for gasifiers vs other stoves.</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">Regarding charcoal. I am presuming you can still use the charcoal. I was, apparently erroneously, under the impression that gasifier stoves could continue to receive primary air and therefore burn the charcoal. I actually liked that idea because it was simple and used most of the energy in the stove. If you take the charcoal out of the stove you then have a couple of options for using it. You can burn it in another stove, which has some appeal as you can do a different kind of cooking with it (e.g. BBQ, or ?). But also seems like quite a bit of work and complication for a small amount of charcoal. Or, you can use it in the soil. So another question:</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">Is a gasifier stove with charcoal (biochar) buried actually carbon negative?</span><span lang="EN-CA"><o:p></o:p></span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125);"><span style="font-size: 11pt; font-family: Calibri, sans-serif;">Then the other important measure: what are the emissions?</span><span lang="EN-CA"><o:p></o:p></span></li></ol><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);"> </span><span lang="EN-CA"><o:p></o:p></span></div></div><div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">And, a kind of crude question: with the ins and outs of this discussion is it the case that rocket stoves or some other stove is more efficient than the gasifiers?
