kevin,
thank you, for citing, I stopped at the first clear source I thought to be reliable, I now understand the confusion, and am left with a confused understanding.
the sources you cited seem to carry credentials one even states that it can mean not just one or the other but either.
I just wonder which part of the elephant Greg was discovering in December? Ha!
com-on laugh with me now,, no harm intended.
I'm fond of low grade hydrogen gas, I think producer gas as seemingly unrelated as it is,,,, is unanimously safe. throw a btu content on the end for those who care and call it good.
Luke

kevin,
I posted earlier on this , its pretty tough to argue with a dictionary,
# I did a Google on "Syngas Definition" and here is what I got:
http://www.google.ca/search?hl=en&client=firefox-a&hs=ldt&rls=org.mozilla:en-US:official&defl=en&q=define:Syngas&sa=X&ei=rJpATcCcOYjrgQe60J26BA&ved=0CBgQkAE
# Note that the various definitions vary somewhat, depending on their source. See also
http://en.wikipedia.org/wiki/Blind_men_and_an_elephant
if this info is wrong please anyone call it out and site your source
# My source for the Definitions I provided for consideration is me; I made them up. I do think that the definitions I proposed for consideration will enable a disinterested party to clearly tell if a sample of gas is Woodgas (or Wood Gas), Pyrolysis Gas, or Syngas (Either Synthesis Gas or Synthetic Gas)
first below, you will see a definition of syn- that i pasted
notice that "syngas" is coincidentally used as an example of how the prefix syn can be properly used in our language, syn in front of gas as one word means synthetic gas, not synthesis gas.
I could care less either way, I just like clarification. this seems very clear to me no matter how many peolpe are misusing this term.
second you will see a definition of synthetic that i pasted, the list of synonyms made me chuckle.
pretty clear wood gas can be used as synthesis gas, but it is not synthetic gas. See definitions below.
# I would suggest that the lingustic derivation is not as important as would be general acceptance of what the word means.
just wondering of all the better minds out there who agrees? simple yea or nay would be nice to observe. i think for all.
# Do you see problems with the definitions I proposed? If so, please feel free to propose better alternatives.
Best wishes,
Kevin Chisholm
