There is no question that large transport category aircraft are the most efficient users of fossil fuel.
as compared to what?! A ship? A tractor trailer rig? Bus? auto?
It doesn't take a rocket scientist to see that the most wasteful application fossil fuel burners is the big-assed SUV which may manage a cool 12 miles per gallon.
Again, as compared to
what?! That city mass transit bus? A motorcycle? A LearJet? 737? A Geo Metro?!
As for the EEE-vil SUV's, my wife drives the kids around in a Chevy Suburban. Get's 15 mpg every day around town. My big ol' 1/2 ton pickup truck get about 16 with AC, 17 without.
The Toyota Camry we used to have got about 22-24 mpg in the city.
What matters to me is: 1. safety (family protection), with reliability, purchase cost, operating cost following up.
Thr Suburban weighs about 2.3 times more than the Camry. This translates into a vehicle that's 2.3 times as safe, from a kinetic energy standpoint. Not to mention it has 9 seats, versus the camry's 5.
Decision - Suburban, based on:
1. safety - hands down (outright weight, and mileage-weight comparison), and
2. mileage-seat comparisons.
Ain't it great in the US one is still
free (so far) to buy and use whatever vehicle is made and sold!!!
Now you tell me. If you really wanted to do something about air pollution where would you start?
I say we ban
all volcanic eruptions!!!
and ban all airborne polution from illegally crossing the US's southern border!!
