[Gasification] Re: Gasification Digest, Vol 22, Issue 7 Re synergism, biodigestion and fermentation

[Ron Wagner]

Is fermentation a form of biodigestion? What are some
common vectors for biodigestion? yeast,
termites,pillbugs, e-coli, etc.

If one had a large supply of wood chips, or other
cellulosic waste, what would be the way to contain the
gas and save it. Is anaerobic digestion best, or
aerobic?

Would large, strong, clear plastic bags be a good way
to heat the biomass in the sun, and then bleed off the
gas? 

How hot could I get such a bag of biomass in the sun?
Would there be danger of explosion or fire?

What kind of gas would be the product? How could it be
stored? Could it be compressed without expensive
equipment?

Any basic refernences would be appreciated.

Thanks,

Ron Wagner
