Fat Replaces Oil In F-16s

It looks like the military has finally figured out a way to combine Americans' love of french fries with their love of blowing stuff up. The Air Force says all of its 40-plus aircraft models will be able to burn biofuels by 2013, three years ahead of schedule. From the article: "The Army wants 25 percent of its energy from renewable sources by 2025. The Navy and Marines aim to shift half their energy use from oil, gas and coal by 2020. 'Reliance on fossil fuels is simply too much of a vulnerability for a military organization to have,' U.S. Navy Secretary Raymond Mabus said in an interview. 'We’ve been certifying aircraft on biofuels. We’re doing solar and wind, geothermal, hydrothermal, wave, things like that on our bases.'”

      It doesn't make sense environmentally. Biofuels produced by plants or animals are a dead end, the efficiency is just too low and in some cases even negative.

      Algae-based fuels may have a chance, and once solar cells make electricity dirt cheap then turning hydrogen into e.g. methane may have a chance too. Until then, the only alternative to fossil oil is to turn coal into oil, which is even worse for the environment.

      Good thing we proved the technology as Sandia NREL in the 1980s; the conjecture was that the process would be profitable by the time diesel fuel reached $3/gallon, but nobody has spun it up yet. This is possibly due to the fact that the only place you can get enough suitable land cheap enough is managed by the BLM, and you can get permits to mine coal or drill for oil, but heaven help you if you want to build a renewable energy facility.

      The war in the Pacific was started over oil, and turned on fuel supply.

      In the end, Japan was using biofuels made from the roots of pine trees, which they had a lot of because the trees had been felled to be burned themselves.

      It took 100,000 pine tree stumps to make one tank of gas for a Japanese fighter jet.

      Biofuels are an overrated source of energy.

      Once the oil begins to run out, heavier-than-air airraft are going to become scarce.

      This has all the hallmarks of an urban legend. First of all, the Japanese "fighter jets" were basically nonexistent in WW2, coming too late to enter service. Furthermore, the "100,000 pine tree stumps" isn't quite correct either. For one thing, it's the roots that were (are?) turned into fuel. Now, it may take 100k roots, I have no idea, but I highly doubt it was "stumps". Finally, last I read, this had been a pilot project (no pun intended) only. While technically feasible, the manpower required to convert the pine roots into fuel was determined to be too much of an impact on other programs.

      Regardless, this isn't an oil based biofuel, it would have been an ethanol one. Bit of a difference there, I think, though I am not an expert on the matter.

      Not to mention the Soviet Union was extremely aware of, which is why almost two million died at Stalingrad - most of them Russians. That was the gateway to their oil riches to the south and had to hold at all costs. From the WP page:

      The Soviets first defended Stalingrad against a fierce German onslaught. So great were Soviet losses that at times, the life expectancy of a newly arrived soldier was less than a day, and the life expectancy of a Soviet officer was three days.

      Lambs to the slaughter... but it was defense at all costs. In war, and at least if you're the Soviets, men were plentiful and oil scarce. They were willing to sacrifice plenty of the first to secure the second.

The concept that these engines are somehow eco-friendly is absurd, no matter what contributed the hydrocarbons that they are burning.

      Its not so much about a "green war" as it is about reducing dependence on a supply of oil that could get cut off in a war. The first place our enemy would invade would be the Middle East. Why do you think we have a strong military presence in Afghanistan and Iraq? Its the only thing our leaders could come up with that we would (or I should say "DID") support. Why do you think there is a push to get at the oil in the Bakken formation or the oil sands? Both are not as economically feasible as a stable Middle East sending us oil, but the problem is we don't want to have our source of energy so far from home where potential enemies can cut it off. I'm not saying I agree with the whole war and "everyone's an enemy" type of thing, its just me being realistic.

    From TFA:

    The U.S. Air Force is set to certify all of its 40-plus aircraft models to burn fuels derived from waste oils and plants by 2013

    The armed forces say they’ve been successful testing fuels produced from sources as diverse as animal fat, frying oils and camelina, an oil-bearing plant that’s relatively drought- and freeze-resistant.

    “We can use an almost unlimited number of feedstocks to produce these fuels,” said Braun. “From a performance stand- point you can’t tell the difference whether you’re burning a camelina blend, a tallow blend, or another fuel that’s made up of a bunch of waste greases -- fry grease or seasoning grease.”

    And from TFW

    Fats may be either solid or liquid at room temperature, depending on their structure and composition. Although the words "oils", "fats", and "lipids" are all used to refer to fats, "oils" is usually used to refer to fats that are liquids at normal room temperature, while "fats" is usually used to refer to fats that are solids at normal room temperature. "Lipids" is used to refer to both liquid and solid fats, along with other related substances, usually in a medical or biochemical context. The word "oil" is also used for any substance that does not mix with water and has a greasy feel, such as petroleum (or crude oil), heating oil, and essential oils, regardless of its chemical structure.

    The confusing point is that "oil" is a very generic term. They're switching from using fuel derived from petroleum (which is an "oil" but definitely not fat) to fuel derived from various renewable sources (many of which are oils and most of which are fats).
