There may be substitutes for shipping fuel from anywhere, thus eliminating a least some of the logistics train…

A very good suggestion of producing biodiesel in Afghanistan was explored by several

“Yields in gal/acre:

corn 18
hemp 39
soybean 48
safflower 83
sunflower 102
peanuts 113
opium poppy 124
rapeseed 127
olive 129
oil palm 635

Before you get into lye and alcohol needed for transesterification, consider that this oil will run straight from the press if it is preheated to lower the viscosity. Diesel engines get hot.
Run the coolant through your 55 gallon drum supply tanks = hot fuel.

Use a little lye and alcohol and you have straight diesel to kick start the process.

Their are African countries using this process for electricity right now….

…Americans are making Biodiesel out of soybeans (check it’s position on the list and selling it as commercial biodiesel for at least the same price as diesel. I think they call it B-1.

Notice the yield of opium poppy vs. soybean on that list.”

While, I don’t believe that buying the poppy crop and converting it to fuel would provide the large amount of fuel required, it could make a good dent, AND help disengage those poppy farmers from the Taliban

Reduce fuel requirements by reducing NATO manpower deployed in Afghanistan and producing bio-fuels (and other alternative sources) locally may be part of the answer.

other possibilities:

Protect convoys in Pakistan ??? w/UAV’s ?

Alternative route into Afghanistan is via… IRAN.
