Ethanol (from corn) as a motor fuel never did, and never will, make
sense - particularly in Oilberta.
Ethanol from saw-grass would be a totally different situation.

as they figure out ways to liquefy natural gas for carrying and travel
that'll probably take over a lot of things

NorthernStar Natural Gas wants to help navigate fuel to its destinations
(homes and businesses) on the US West Coast. It is developing liquefied
natural gas (LNG) receiving terminals which will re-gasify the fuel from
suppliers for consumers using existing pipelines. By cooling and converting
it to a liquid form, natural gas can be transported more easily and cheaply
across long distances. Its portfolio includes one terminal project with a
capacity of 1.3 billion cu. ft. per day (Bradwood Landing, in Oregon) and
one offshore terminal in California. Industry veteran executives William
Garrett and Paul Soanes have teamed up with investment firm MatlinPatterson
Global Advisors to fund the company's development.

Liquified natural gas has a bit of a problem in car fuel tanks - on
such smaller fuel tanks even with a lot of thermal insulation, rate of
heat inflow from outside into such cold fuel raises its vapor pressure to
great levels. At many times, the temperature will exceed the "critical
tempwerature" - above which liquid of most of LNG's chemical constituency
cannot exist no matter how high the pressure is. How much fuel can one
store in what practical fuel tank if it is gaseous rather than liquid?
Will the fuel pumps at the refueling stations pump the fuel into such
higher pressures at a cost that the market will support? Will these
fuel dispensers be operable by Joe Sixpack, or require a trained
technician to operate?

What is the octane rating of "natural gas" anyway?

I have heard of trucks and seen forklifts running on propane - but that
is easily liquified at ordinary temperatures at fairly reasonable
pressures.
