<div>Dear Digestion Friends,</div>
<div> </div>
<div>It was a while ago that I was exchanging information with (I believe) David House, about biogas digester training workshop in Alberta, Canada. I recall that you have been building a prototype that would be housed in some kind of structure to reduce heating costs. Or maybe it was not David but Richard Harris but I cannot recall now. This wonderful person who wrote to me about his prototype, could you get back to me? </div>
