that is a “mechanical loss”. The efficiency of the boiler is about 30% - something like half of what it should be.<o:p></o:p></span></p>

<p class="MsoNormal">Hi Crispin and Dieter, <o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Very true about the need for people to have a quick option of cooking in various 'context of use' scenarios. We have found particular interest in our small kilns from customers that are farmers who have waste maize cobs and also are regular
buyers of charcoal - (<a href="http://kenyacharcoal.blogspot.co.ke/2012/10/make-and-use-maize-cob-charcoal.html" target="_blank">http://kenyacharcoal.blogspot.co.ke/2012/10/make-and-use-maize-cob-charcoal.html</a>). As one lady told me the other day, she
stopped buying charcoal (still makes and uses it for certain dishes) and thus saved up enough money to buy an LPG gas cylinder. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">Other interesting feedback I have had from customers about the need for a 'V-Power' type of charcoal (fast lighting and burning, very hot) is from hotels who have a brief but fast lunch rush - you can mix maize cobs or other light density
charcoal with hardwood charcoal to tweak the speed of cooking - and also from quite a few home cooks. They mostly say having a light density charcoal that goes out after 20mins for small dishes like eggs or tea is much better than the hassle of lighting hardwood
charcoal that burns for another 20mins after you have finished cooking. <o:p></o:p></p>
