[Gasification] DIY GtL

[Tom Miles]

LI>In China, there are hundreds of villages using fuel gas 
station...(gasifier --> producer gas --> pipe line --> end user).

Li,

Is this producer gas from wood gasification or biogas from anaerobic
digestion? 

We hear about the large number of anaerobic digesters in China but I have
never seen evidence that wood or straw gasifiers are used in anything larger
than a household.
