[Gasification] Sawdust in Fan TLUD

[rkurt at tadaust.org.au]

I haven't been following this list for some time, but 4 or 5 years ago  
there was a young fellow somewhere up North (In your area) who was  
making balls of charcoal+grass+possibly sawdust by tumbling the  
material with starch gel. He used a cement mixer with the padles  
removed. The stuff formed accredion balls and after drying appeared  
quite firm and possibly useful in a gasifier.
What happened to him, and his concepts. That tumbling method is also  
used to make things like chocolate covered peanuts and sultanas.It can  
also be used for small scale pelletising seeds.

regards,

Kurt
