(Maybe not much; GACC increasingly looks like a sideshow.) <br><br>I will now read the D-Lab report in light of your observations. <br><br>George: <br><br>Some questions: <br><br>1. Who is leading the external charge on SE4All when it comes to cooking energy? Is the emphasis only on households? This is important because if SE4All is aligned with UN SDGs, the goal is to reduce the "% of households using solid fuels for cooking". <br><br>In other words, SDGs are as pernicious to use of biomass for cooking as WHO/ISO Tier 4 Emission Reduction Targets for PM2.5 (hourly average). I do not understand why this List has not reacted to this blatant betrayal of the "better biomass stoves" agenda. <br><br>2. Is there an evaluation of the Gambia stoves work in the past? And to the SE4All Investment Prospectus (likely to be heavily weighed to electricity)? <br><br>------<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'>Thanks, both.

The follow-up point I want to make is stimulated by the fact that your project was discussed previously and it has some aspects which interesting to those planning stove roll-outs in locations where the are manufacturing capacity or skill shortages.<br><br>Quick review: at about the same time, Ashok Gadgil and I concluded that the way forward in places with limited manufacturing capacity was to send partially manufactured stoves to the site, absent only what could be made using the available skills and manpower. By ‘concluded’ I mean we both started ‘doing it’, Ashok in Darfur and you with me in the Gambia. At the time Ashok and I have not met or communicated – we only found each other later and got on like a house on fire.<br><br>While it has probably been done before, we didn’t have examples. The plan was to make the combustion chambers for Vesto stoves and send them to you, with all the rest of the stove made locally from available sheet metal. The result was a locally fabricated Vesto Junior that has the same performance as a product made in Swaziland.<br><br>Ashok for his part, produced ‘blanked’ parts in India and sent them to Darfur for assemble in a workshop that had no electricity – just hand tools, initially. Later they added some welding to further improve the product.<br><br>The common elements were that the ‘industrial’ production was done as close to the bulk material source where the tooling could be produced and maintained. In the case of the Darfur stove it was blanking tools. For those who don’t know the term, it is punching tools that typically have a very small vertical movement, used to create a shape out of a flat sheet. It can also be done by laser or plasma cutter, but when volume is involved, press tools are made that punch the whole part at once at very low cost. There was no way that could be run and maintained in Darfur.<br><br>With Banjul, the challenge was similar. There is a mechanical training centre with limited cutting and welding facility but no laser cutting or CNC punching capability. The grate on the Vesto needs three press tools to make, including a complicated blanking tool. So the combustion chamber with scores of holes and the grate were produced in Johannesburg – at the contractor that does the CNC work and the SeTAR Centre’s stove development workshop at the University of Johannesburg. That facility was equipped by ProBEC/GIZ in its last days.<br><br>At the time the goal in the Gambia was to produce locally a high performance stove that could burn briquettes made for available waste materials, which is a fuel a Vesto is able deal with quite well. The initial target was to make it to last five years, and it is heartening to hear that indeed these stoves have endured that long. Given that there is no ceramic component in them, perhaps designers can learn from the experiment. It is an all-metal stove like the Darfur Stove. They two products have little else in common as to how they work, but they do share these:<br><br><br> * Designed outside the region<br> * Introduced after local testing<br> * Main components needing high precision produced outside the country<br> * All metal construction<br> * Performance much better than local baseline products in common use<br> * Production process adjusted/evolved as local capacity improved<br> * Field performance evaluations confirm acceptance and long term use (displacement)<br><br>It would be good if the project can be picked up again and expanded to include all the city neighbourhoods.<br><br>Many thanks<br>Crispin<br><br><br><br><span class=gmail->Crispin.</span><br><br><span class=gmail->Sorry my mistake. Maybe of interest to a wider audience. Even way back I always thought that your stove designs never got enough mention. Feedback from the grassroots.

Total collapse of tourism, still trying to recover now. At the time restricted movements of goods as borders were almost closed for some months – high prices for scarce products. We laid in boxes of tinned sardines and other tinned stuff and went into lock down mode for about 3 month – only fresh daily bread. In the end I think they traced the virus back to some monkeys in Niger or there abouts – yes bush meet played a big part and the eradication of forests…</span><br><br><span class=gmail->Crispin. Our 23 Furno Ees are still working great for the “test” families – nearly 5 years on. 2 ½ years ago we had a SE4ALL validation workshop here and both the Furno and the Briquetting were included in the Governments priority initiatives and the Investment Prospectus. Now with the new people in Government hopefully more positive actions will happen in time. We also had some serious funding problems with getting messed around by some implementing partners in charge of purse strings – we never made it away from the 1 tin of sardines per day. Amazing what you can do with that!</span><br><br>Watch this space ☺ There is still spank in this old geezer!<br><br>George <br><br><span class=gmail-> </span><br><br> <o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></div></div></div></body></html>
