The biomass black box…
What does industry need? What does industry want? Where can industry make a profit? What federal incentives will be available? When / how can you secure these
incentives? What kind of a business structure? Should the producer get involved with value
added processing?

As noted by Bill Jacoby… (Chemical/Biological Engineer at Mizzou)
Compared to coal or crude petroleum, biomass has a low energy density on a mass basis (BTU/lb or kJ/kg). It also has a low energy density on a volumetric basis (BTU/ft^3 or kJ/m^3). The energy density on a mass basis is improved by drying the biomass to the lowest moisture content attainable under ambient conditions. The energy density on a volumetric basis is improved by densifying (e.g., chopping, baling, grinding, pelletizing, etc.). In order to minimize transportation costs, both of these activities should take place on the farm. Is it possible that, for energy
crops, most of the necessary drying could occur before harvest?

So, the question is…
