<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">This is a quote from the article linked below:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><i><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">“At the household level, the key issues to consider are women’s and children’s health. Indeed, World Health Organisation studies show that one hour of using firewood has
the same health impacts as smoking a packet of cigarettes.”<o:p></o:p></span></i></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Of the many untrue things written in the article, this is probably the most outrageous, and that is really saying something.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The exposure one gets from a single cigarette is about 45 milligrams of PM2.5. The exposure in the worst home tested by Fresh Air in Kyrgyzstan in the past 4 months, which
has terrible indoor air pollution in most low income homes, was 6000 micrograms per cubic metre. That is 20 times the exposure in Beijing on a bad ‘orange alert’ day. The exposure of a Kenyan cook is
<i>very</i> unlikely to be as high as that and I invite researchers to show that it is indeed as high as 6000 for one hour per day, on average.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Next, to be exposed to the same level of PM2.5 as a pack of 20 cigarettes (45 x 20 = 900 mg or 900,000 µg) one would have to inhale 150 cubic metres of such air in an hour,
or 150,000 litres. To do that in an hour would require about <a href="https://www.quora.com/How-much-volume-do-we-inhale-and-exhale-in-a-day">
6000</a> people!<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">As the health effect on a human from cigarette smoke is far worse than wood smoke, let’s call it 10,000 people to be safe. If an exaggeration of 10,000-fold is not alarming
enough, consider all the other unsupportable ‘climate’ assertions thrown left and right in this piece. Good grief why can’t people just promote their products on their merits without linking it to all the junk-topics-of-the-hour.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">CleanStar’s product makes perfectly good sense and has a viable business plan. Sugar cane-based ethanol is a processed biofuel which is convenient and can be burned very cleanly
(test, don’t assume). It can be produced at scale and distributed at lower cost and at greater convenience than LPG. So….just do it.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">For those who don’t know Sagun, he was one of the judges in the TerraWatt Prize competition held by National Geographic a couple of years ago. The organiser of that competition
was so inspired by the experience he has moved to Mozambique to try to fill in a gap created when CleanStar moved to Kenya.

<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">Woodfuel releases carbon fumes into the air, adding to the carbon footprint and global warming. This has resulted in global climatic change, which is also being witnessed in Kenya in the form of
higher temperatures, prolonged droughts and dry spells.<o:p></o:p></span></p>
<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">Though new to the local market, ethanol has gained wide use in Mozambique because it is clean and efficient, comparable to LPG. CleanStar Ventures has conducted market research primarily in urban
households that confirms the convenience and safety of ethanol. <o:p></o:p></span></p>
<p><span lang="EN-US" style="font-family:"Calibri",sans-serif">The Kenya Forestry Service (KFS), the Kenya Forestry Research Institute (Kefri), and ICRAF, among others, are working with farmers on managing trees for woodfuel. They promote the harvesting of
mature stems, growing of acacia trees for charcoal and managing trees in drylands.<o:p></o:p></span></p>
