Re: [Phys-l] Climate Change - Is it Controversial?

bc is surprised, so we are left w/ the rare instance of charcoal  
briquettes, coke, etc.

bc also surprised the best (only?) coke is from bituminous not  
anthracite.

p.s. from the article Jack referenced below:
------------
COAL is not a hydrocarbon. Even if we leave out of
 consideration the technically very important constituents ash,  
moisture, sulfur, and nitrogen, the
data in Table I show that, in a high-rank bituminous coal,
there may be one to nine oxygen atoms to every hundred
atoms comprising the coal substance.

----------------

It's a matter of definition -- coal is a sugar!, partially carbonized  
along w/ lignin and cellulose.  Which makes sense since that's from  
whence it came.
