have some questions that I hope you can help me with:</div>
<div style="color: black; font-family: arial; font-size: 10pt;"><br>
</div>
<div style="color: black; font-family: arial; font-size: 10pt;">1.
What would be an appropriate engine for generating from biogas
at this power? I am considering a dual fuel compression engine
(for the advantage of being able to rely on diesel if the
biogas is down for whatever reason) but not sure if this is
the best idea? Does anyone know of any companies that would
provide appropriate engines for this application?</div>
<div style="color: black; font-family: arial; font-size: 10pt;"><br>
</div>
<div style="color: black; font-family: arial; font-size: 10pt;">2.
What are appropriate BMP, Total Solids and Volatile Solids
numbers to use for sizing the digester (currently assuming
380m3/tonnesVS, 25%TS and 85%VS but want to check this is
correct. The feedstock is 100% dairy cow manure from
zero-grazing cows in rural Central Uganda.)</div>
<div style="color: black; font-family: arial; font-size: 10pt;"><br>
</div>
<div style="color: black; font-family: arial; font-size: 10pt;">3.
Does anyone know of any reputable companies operating in the
East Africa area who have experience of biogas at this scale?</div>
<div style="color: black; font-family: arial; font-size: 10pt;"><br>
</div>
<div style="color: black; font-family: arial; font-size: 10pt;">Thanks
in advance for any help that you can give,</div>
