[Gasification] Bisschop Engine - rough & ready

The problem with producer gas is the carbon blacks, which certainly can be 
caught for a price increase to the installation. They coat the heads with 
fine dust like ash, that is if the heads are designed to allow the quantity 
of gas required to get around their heating surfaces.

I have worked with a German Stirling engine developer, and the Micro Class 
gasifier shown on the Fluidyne Archive www.fluidynenz.250x.com  was to 
answer a question posed on behalf of Whispergen. "Can wood pellets be 
gasified for their system". The answer was no for our type of gasification, 
and as it would only require three kg/hr to run this engine, the automation 
needed for domestic use would make for expensive hot water. Stirling's 
appeal is out of sight, and out of mind. Total convenience!
