This is coolbert:
From the Chicago Tribune the other day more military biofuel:
"Cost sky-high for military to buy alternative fuel"
"Air Force pays $59 a gallon in push for green options."
"WASHINGTON - - The Navy angered Republicans by spending $26 a gallon for biofuels for this week's Great Green Fleet demonstration but the Air Force received little attention when it spent more than twice as much per gallon [11,000 gallons at $59 a gallon] to test synthetic jet fuel last month."
THIS IS ALCOHOL TO SYNTHETIC JET FUEL!
Alcohol is a biofuel as derived from plant matter. Alcohol when further processed producing jet fuel [AVGAS].
"the alcohol-to-jet fuel was expensive because it came from a small demonstration plant"
Exactly. Merely a pilot project what they are called and not a fully up to scale working plant producing the fuel in large commercial quantities, processes and techniques steps and measures needed to produce a quality product that works being tested.
Furthermore, according to this Tribune article that Great Green Fleet not so "green: after all so the reader is able to infer:
"[that] $12 million the Navy spent for biofuels to power a carrier strike group on alternative energy for a day."
POWER - - FOR A DAY?
That amount of biofuel as supplied to the Great Green Fleet only enough to power the various warships and planes of the carrier strike group for A DAY ONLY?
That six month deployment of the carrier strike group will be in part fueled by alternative fuel [biofuel] but only for a day?
That blended [?] mix of traditional petroleum product and biofuel only enough to last for one day of conventional "steaming" and carrier take-off and landing?
[the carrier the warship itself powered by atomic reactors, the remainder of the strike group petroleum fueled!]
Well, these are pilot projects just to determine the do-ability and if the product can be done as envisioned further mass production worthwhile.
And again, all this has in mind the day if and when the American military will no longer have access for whatever reason that easily obtainable source of fossil based fuel [petroleum] needed to power naval vessels.
