[Gasification] Dasifier Metal melter

[Thomas Reed]

Dear Peter:

I see Agua Das daily and had lunch with him yesterday, so hope we can 
attract his attention to this. 

The "Dasifier" is a unique gasifier in that it is simple, yet very 
flexible in operation.  Das likes to use "found" materials for most of 
his work, so the least "found" for the dasifier right now is an old 
refrigerator compressor to supply the ejector.  however ejectors can be 
made in principle from any moderately compressed air, say > 10 PSI 
should work fine, so your choice. 

The upper section of the dasifier pyrolyses 80% of the wood and supplies 
a moderately clean and rich gas for most of the combustion.  Some 
charcoal falls through into the lower section which can be operated as a 
charcoal gasifier or the charcoal can be kept for other purposes. 

These are the principles.  I would be interested in hearing Das's 
description.  I don't see why we shouldn't post this to the gasification 
network for other comments as well.  Maybe there are more using it.
