[Gasification] conversion of CO2 into methane (Off Topic)

Holy moly! Doug, you are a man of very interesting sides. 

I read with delight the mini-treatise in response to James on how to gasify
successfully and what not to do. Anyone who has not read Doug's responses
needs to do so as they cut to the very heart of practical gasification. As I
was reading James' posting, I was ticking of the responses I would make.
Then, I read your response... You hit everything I had and more. So thanks
for that.  

All the best
Rex Zietsman

Hi Dr Karve,

Not sure you are directing your question to the right forum, but as it's CO2
and methane, guess it qualifies, but never thought my own interest in this
humble cell form would be useful to anyone(:-)

Archaea having been around for 3-4 billion years are the ultimate colonist
of any environment, survival being that they arrive at their destination
from where ever they come from. Even if there was not the chemistry present
to feed directly, they can also take in energy from Sunlight and convert
this to feed. Mutation is rapid, given the environmental chemistry would
also changing around them over a few million years or so. Time doesn't seem
to matter and they keep multiplying to suit their environment. They can now
be found in just about every thing on this planet,so I'm sure carbonic acid
was considered ideal nutrient.

Given that your interest is of their participation in digestive processes
and the evolution of methane, one can only guess that the building blocks
allowing their evolution branching into bacteria one way, and eucaryota the
other, they had plenty of places to turn host nutrient into methane. My own
interest is their function within the human gut, evidenced by their methane
production and distinctive smell, and how they might be involved with the
matrix of peptides on which warm blooded cells of life forms build.

It may be better to discuss this privately rather than be off topic.

Doug Williams,
