Carbon based fuels
I find it a wondrous thought that when you look at a contrailing airliner as a distant speck in the sky that that speck may contain enough energy to fly at that height and speed for another 10 or 12 hours.
On that scale our fuel use seems miniscule.
But each day in cruise I look at the ever rising level of brown out from man made pollution.
We can't keep doing this to our home forever.
I am of the belief that the carbon based fuel route is still driving up the dead end of the evolutionary branch for all mammalian species on this planet.
In effect it is returning the energy that has been deposited over millions of years back into the earth cycle and we humans are recreating the primordial atmosphere.
Biofuels are not a solution.
Alternative propulsion is what we truly need, not alternative fuels.
