<p class="MsoNormal"><span style="color:windowtext">There are several micro-gasification stoves in Kenya where they have been used in some areas for a few years. Users like the reduced emissions and reported 40% fuel savings. A few projects are promoting biochar
which is often combined with manure, a combination recommended by local agricultural extension folks and endorsed by the national university. I wonder if there have been similar projects in Ghana.
</span></p>
<p class="MsoNormal"><span style="color:windowtext"> </span></p>
<p class="MsoNormal"><span style="color:windowtext">While the stoves produce small quantities of biochar they have been an effective way to introduce biochar. For larger quantities, people have been using fines from charcoal production, at least where the fines
are not rolled with clay into fuel balls. </span></p>

Thanks for the reference. VERY recent publication (the journal date is February 2018 --- yes 2018).

This will be useful information for some anticipated TLUD stove work in Ghana. I will see if my contact in Ghana knows any of the 6 authors.<br>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN" style="font-size:12.0pt; color:#505050">Abstract</span></p>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span lang="EN" style="color:#505050">Many cookstove designs and biochar programs have been implemented in many countries around the world. These programs have had varied degrees of success which is generally
low. Some were able to achieve all their target objectives, others achieved a fraction of their target objectives whiles others achieved different results from their initial targets. The low success rates have been attributed to disregard for various users’
considerations by the past implementers of such designs and programs. This study seeks to determine the factors and features that Ghana cookstove users want to be incorporated in the designs of their cookstove and biochar programs. The study used a nationwide
survey of household cooks. It was found that about 99% of the respondents will prefer a smokeless cook stove. The challenges that they will want eliminated from the conventional cooking systems are ranked from the highest to the lowest as: smoke and heat (35.80%),
difficulty in use (21.8%), cost of cooking systems (6.8%), faulty parts (3.1%), and fuel availability (2.90%). About 83% of the respondents have no idea of the use of charcoal as a soil amendment tool (biochar), which presents an opportunity to educate the
communities about the potential of biochar to improve soil fertility and quality. This paper therefore recommends that future cookstove designers, researchers and biochar programs implementers consider elimination of smoke and heat as well as fuel availability
ahead of the other factors considered in the design of cookstoves.</span></p>
