Does anyone have a full (or partial) list of commercially available SMALL 
gasifiers, their costs, and their capabilities.   What is the smallest that 
is commercially available?

Tom Reed and I are working with "batch feeding" and can get a sustained 
burn for 40 minutes without much problem.   But we have not made a 
large-batch unit, so we do not know the impact of the height that is 
essentially filled with pellets.   One of many experiments waiting to be tried.
