I have problems to understand your message - simply because consideration of
methanol as a fuel is several decades old. In the late 70's there was a
project (not executed) to build a pipeline from Poland to Austria through
which a slurry of coal in methanol should be sent to Austria to substitute
power from the "cancelled" nuclear power plant at Zwentendorf.
Methanol has a much higher value concerning energy efficiency per liter
compared to ethanol. Without doubt there are much higher costs for producing
it than for ethanol. Of course it may be produced from wood - but at what
costs? Heat is not the only cost factor. What about the tremendous amount of
by-products, which to a small part could of course be used commercially, but
the major part would cause a lot of costs for disposal? A simple reasoning:
If this kind of producing fuel would be financially favourable the big oil
companies would have changed to it since long. Thinking of this possibility
this might have changed politics dramatically - no invasion of Iraq would
have been taken place, not tens or hundreds of thousands of people would
have died. Another question is whether wood is really so easily available
and so cheap. This depends on the region, sure this is not the case in the
middle east. I see again that comments by US citizens do not take into
consideration that there is a world outside the USA. Regarding the use of
for instance corn for fuel production I would question whether it is
politically and ethically correct to use potential food to produce fuel for
thirsty car engines.
My opinion is, that if it would have been really economically favourable, it
would have been done since long.
