It is well known that chunkwood makes great fuel for engines.
Bill makes gasifiers, and I was hoping he could give some insight and
recommendations on the ability of smaller sized fuels to yield Engine
When Ben says "pellets must be well bonded", just what does this mean?
Can the readily available wood pellets be used for a gasifier, or will
they fall apart, and give poor gas?
I hope Bill will be kind enough to tell teh List what sizes of wood
his gasifiers can use, and whether or not, they can use wood pellets.
