when is the meeting, page-33

jantimot,

i can see that if the ctl fuel is 10% less dense it will require 10% more energy in order for the lower density to be fully exploited.

afterall, it is a weight mixture (fuel and air).

perhaps the ctl fuel does contain a higher energy but i certainly wouldn't have a clue.

if it doesn't contain more energy then the having less density is in fact a disadvantage to the aircraft manufacturers because they will require larger tanks.

and because fuel is sold by volume, the airlines will have to by more volume to get the required energy which means higher fuel bills.

i know there are environmental benifits beyond just the density issue but their claim is interesting.

thanks for the reply.

cheers
