Interesting stuff from ORNL

There's some really interesting data in the documents
under http://cta.ornl.gov/data/download24.shtml about
transportation energy usage.
.
I was surprised to find that general aviation consumes
on a par with autos per passenger-mile; I thought it
was *much* more. Maybe it used to be.
.
Cars are still chewing on the order of a kilowatt
per nice person-mile, or 28-ish effective mpg.
.
The really disturbing thing is how they think we've
got *plenty* of oil left. I'm beginning to think
that *nobody* really knows the right answer to that.
