[Gasification] Coal Gasification

[hugh]

Problem is

Gassifying coal, produces coke - carbon + mineral content - it is not 
the same as charcoal - especially from a soil perspective. In fact it 
can be quite toxic. (As a young boy - if we couldn't get galena (PbS) 
crystals (to function as rectifying diodes in crystal sets) we used coke 
(which was everywhere in the 50's) - which worked quite well - go figger....
