Dear List,

I am resending the below e-mail because it may not have made it to the list

G'day All,

Compressing gas for transport fuel is a waste of energy - you need
liquid fuels for mobile applications and use the gaseous ones for
stationary things (except electricity, which can be generated by
solar/wind/hydro!).

For your switchgrass digester you will need some inoculum to get the
right bacteria - in fact you may be best to feed the grass to animals
first to get a bit more value (except the waste of energy is high!). Se
the "Beginners Guide to Biogas" at <>.

(I will be in Cameroon running a biogas course for the next couple of
weeks)!

All the best,
HOOROO
