[sustran] Re: Steve Abley field trip querying sustainable transportinitiatives world wide - Your help in organizing

[Daryl Oster]

Alan,

Jet aircraft can fly just fine on biodiesel.  The main modification needed
would be to insulate and or heat the fuel to avoid gelling due to cold
temperature at altitude.  The cost of biodiesel is about double the cost of
fossil jet fuel.  Since biodiesel is renewable, there is no net increase in
CO2.  Other emissions are also significantly less.  

Presently, financial and social sustainability is more of a consideration
than environmental or energy sustainability.  

As far as ultimate sustainability goes, if we switched from fossil fuel to
biodiesel there would be a food shortage UNLESS about half the world's meat
eaters became vegetarian.  It takes about 7kg of grain to produce one kg of
beef; so present grain production could be diverted to vegetable oil
production for bio-fuels.   

The best solution by far is to make quantum improvements in energy
efficiency of transportation methods.  ETT for instance is capable of
providing 50 times more transportation for a given energy input.
