to such an extent that the small size attracts a premium (which is gonna take a while!) we will have shown a broad acceptance.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US">I suspect there is never equilibrium in the market. One effect that will disrupt the coal supplies will be a demand for a certain size of fuel. Just
the same, dung may be traded in a different form. There are two forms now: ‘as collected’ meaning low density, and ‘trodden’ meaning plates of it picked up off the corral floor and stored as large plates about 1.5” thick. There may be a rise on the cost of
the dense plate version because the Model 2.5 and 2.0 can burn it really well, completely to ash without adding wood as a co-fuel, something hitherto required for a decent fire.<o:p></o:p></span></p>

recoup some of the loss by processing the fuels to suit the demand. Pellets of raw coal would be best for low emissions and lowest cost.<o:p></o:p></span></p>

<br>
May I suggest other indicators of whether people are at home or out and about....perhaps you can turn this defect into a marketing virtue by giving a banner or flag on a pole that announces the home is occupied even though there is little or no smoke coming
out of the chimney. <br>
<br>
Turn smokeless stoves into a virtue by advertising the added security provided by improved smokeless stoves; with a Piggot stove it is impossible to know whether a house is occupied ....therefore it is risky to assume a smokeless house is vacant when there
is no obvious smoke. Therefore smokeless households are more secure because burglers can not assume it is empty and vulnerable to robbers simply by observing there is no smoke.<br>
<br>
Maybe there is no house burglary in Kyrkyzstan??<br>
<br>
Any other suggestions about ways to capitalize upon smokelessness??<br>
<br>
What - if anything - do the gossiping nay sayers state in opposition to these low smoke stoves? There is always opposition from interest groups who perceive themselves to be disempowered by smokeless chimneys and unpolluted indoor air? <br>
<br>
Who are the enemies of the Crispin crossdraft gassifier low smoke stoves in rural Kyrgyzstan? such as: gov't officials, merchants, LPG stove proponents, bankers, environmentalists, women's rights activists, fuel suppliers and miners, fabricators of traditional
high smoke<br>
stoves, etc.<br>
<br>
Hope this is a multiple win stove breakthru??<br>
<br>
Is it? How do we know this locally fabricated low smoke higher efficiency stove is a run away winner? Is it a stove technology "beauty contest" or are there other sinister players and stove competitors who will contest for market dominance?<br>

Subject: [Stoves] Kyrgyzstan stove pilot - update on air quality.<br>
<br>
Dear Friends<br>
<br>
Dr Talant, the Kyrgyzstan government's head cardiologist, is about to release his report on measured exposures to PM2.5 taken this winter in more than 50 rural homes. These measurements were made before, after and side by side with homes receiving an advanced
combustion stove, either for wood, dung, cotton stalks, coal or a combination. There are 4 stove models involved.<br>
<br>
His preliminary numbers are very encouraging. Today he told us that they recorded exposures as high as 7000 µg/m3 indoors prior to changing the stove. That is 35 times higher than a Red Alert day in Beijing.<br>
<br>
The impact produced by the advanced combustion Model KG4.2 coal stove (a refuellable crossdraft gasifier) was to reduce the PM2.5 level to the range of 10-40 µg/m3, a reduction of 99%. He reports that elderly people have noticeably better health, fewer headaches
(caused by high CO) and better lung function. Users report they simply 'feel better'. They are testing pulmonary function as part of the monitoring which will be expanded this year.<br>
<br>
As the stoves do not cost more than conventional stoves of similar quality, it is expected that uptake by the market will be strong. Something unexpected was the very high level of CO in many homes. It is also highly variable, often rising above 100 ppm. With
the new stoves, Dr Talan reports that there is a very low level that is steady. People exhale CO so we do expect that it is not reduced to zero.<br>
<br>
The uprated Model 2.5's mentioned in the last update were delivered to Naryn on Monday and probably installed today. There are a total of 10. It is still snowing heavily and very cold up there. We will be getting repots in the coming weeks about how they are
received in the villages. A complaint is that people no longer can see if there is someone 'home' because there is nothing visible coming from the chimney. One report said someone burned their hand by placing it on a stove thinking, arriving home 4 hours after
loading it with dung, that because of the time they had been away and the lack of smoke, that the fire was out. Wrong assumption.<br>
<br>
When the health impact report is available, I will post a link. It contains multiple, clear evidences that improving IAQ has specific, positive medical impact.<br>
<br>
Regards<br>
Crispin<br>
