I think that there will still be enough demand for a suitable high octane
aviation gasoline that it will be made available -- at some price. The real
key is that Continental and Lycoming need to get to work on building engines
(and airframe manufacturers need to make fuel tanks and lines) that work
with premium mogas, including those with ethanol. Otherwise, the future for
light GA aircraft will be diesel

And this would be a bad thing why?


Hydrogen, when looked at on a large scale, makes all this other stuff
look cheap.

Depends on the original energy source. Right now, photovoltaic systems can
be constructed for about $1 per delivered watt, or $1 million per megawatt,
and prices are coming down. Vast photoelectric farms in the desert could
produce copious amounts of cheap, environmentally innocuous electricity.
But how to transform that electric energy to a form that can readily be used
for highway transportation? Hydrogen from water dissociation.


They are talking 5 to 9 degrees over the next century. If it goes to
5 or 6 degrees, it is going to drastically alter some coast lines and
economies. If it really does go to 9 degrees some one needs to read up
on the "Permian Extension" (SP?)

Yes, we simply have to reduce the burning of fossil fuels, the leading
source of the greenhouse gas CO2. Burning biodiesel and ethanol also
produces CO2, of course, but growing the chlorophyll-based plants from which
these fuels are derived absorbs as much CO2 as is produced when they are
burned. No net add of CO2 to the atmosphere. Hydrogen/water cycle
generates zero greenhouse gases or any other pollutant.

Nonsense.

Anything that burns using the oxygen from air produces oxides of nitrogen,
i.e. smog.
