Can EtOH be CHEAPLY converted back and forth to CH4?

EtOH is too corrosive for existing pipelines. All the corn in the USA
would only supply 10% of the EtOH to power our cars. Cellulosic EtOH
requires an additional dextrochiralisation process. Simplex coal and biomass
gasification was developed by Hap Schulz during WW2.

What's the economics at $10 $20, $40, $90 oil? (Assume $90 oil for six
months in the near future, the life of $60 oil to be five years and a return
to $20 oil in fifteen years.) The panicmeisters are going to destroy this
process if they force you to bet on permanently high oil prices: You have to
assume the "windfall" that can be plowed back into R&D will only last like
seven years; maybe we need 20yr energy futures and other risk derivatives?

I'm thinking there have to be conversion innovations (like using platinum
to convert kerosene to gasoline) that will only come with extensive use, and
hence accidents and experimentation. You should be able to take in anything
(corn silage, apple waste, garbage) and produce energy (EtOh, H2, CH4) as
essentially an "interconvetable triad".

What does it cost to dedydrate ethanol into ethylene (H2SO4, 170'F)
and then back? How does ethylene burn in gasoline engines instead of
ethanol? What does it cost to turn methane into ethylene?
Does ethylene have any pipeline problems?

Interesting subject but which has nothing to do with the subject mater of

Why do you think converting C2H5OH into a GAS
in one form(CH4, BP -89 C) or another (C2H4, BP -104C) is going
to enhance it's transport capabilities over existing liquid fuel
pipelines?
