If and when the world runs out of petro/oil,
what do you think the majority of airplanes and/or heliocopter will
fly on?

1) they will fly on ethanol based renewable biofuels.
2) they will fly on rocket-like fuels, e.g. hydrogen.
3) they will fly on fuel extracted from coal.
4) they will fly on human power (e.g. pedaling).
5) they will fly on a fuel based on ___________________
(fill in the blank, e.g. nitroglycerin).


Where is the fun in this? Did you mean dis'fun'ctional?
You must be a typical human ass if you have children...

The fun part comes from using your imagination. :-)

For example, would it be too far off the mark to
for a ethanol like biofuel to have the same energy density
as aviation fuel or jet fuel?
