[Gasification] Aviation's role in global warming...9/11 aftermath proves theories on H20 in contrails in dramatic fashion.

[Greg and April]

Jet fuel at it's most basic, is ultra high quality diesel, with additives 
added to it to do various things - like detergents to keep the system clean, 
and as far as commercial aviation is concerned to minimize the risk of fire 
in a crash.

The problem with biological diesel fuels, is that they have very poor cold 
weather characteristics- something that due to the altitude, jet's face all 
day, every day while they are flying.

Another factor, is that biological fuels tend to have a lower BTU value than 
their fossil fuel counterparts - which means that more fuel has to be 
carried for a given distance traveled - thus a lower fuel economy ( which 
can be a major factor in flight operations ).


Personally, I would like to see commercial flying cut back and the return of 
commercial train traffic ( which is more fuel efficient anyway ) - steam 
engines based on gasification tech anyone?
