[Digestion] biogas electricity generation

Tue May 10 10:34:45 CDT 2011

Jorge,

Based on my experience in Mexico, if you work for the electric company, that
is the hardest part! Let me see if I can dig up a specific model of
equipment that would be appropriate for the size you are requesting.

Best,

Alex
