Out-Greening the Oil Addicts

The U.S. Armed Forces are way ahead of our corrupt and craven Congress when it comes to finding ways to reduce dependence upon petroleum: the Pentagon figured out that we can save the lives of U.S. service personnel by reducing the use of fossil fuels. Read the article to find out how your military is out-greening the private sector:

    • The military is so well funded that it is where the majority of America's technological advancement comes from. Cell phones, GPS, etc. were all military projects originally before they were disseminated amongst the public. It doesn't surprise me that the military is on the forefront of American green technology.

      Edit: and now that I think on it some more, the internet was a military project too!

    • Doesn't the death of "Mabus" start the 3rd world war; according to Nostradamus?
      So the death of they guy spearheading the Green Navy, will cause WWIII???

      --I think it would be awesome if at the end of the prophecy Nostr. wrote "tantum iocus".
      (that's latin for LOL)

      if only it was that easy. i have tried to run my motor bike on Grain Alcohol. Didn't do to good. But my carbs have never been cleaner. i think the best way to beat them is to go with a boidiesel or electric car. even if you go solar or wind power on your home will help save a lot. The real problem is the cost to do so. They don't want us to get away from Big oil. Sun shine is free for right now but don't worry as soon as enough folks go solar they will have a sun shine tax.

      ---------" You have to advance the timing and adjust the mixture. You don't, however, get the horsepower unless you have a bigger displacement. That's just how alcohol engines run."---------

      No. Air/fuel mix part is correct. Gasoline requires higher air mix than alcohol. (off the top of my head, I think it is 14:1 mix for gasoline, and 9:1 mix for alcohol)

      Some gaskets, delivery lines and other fittings like O rings need to be more corrosion or solvent resistant. Otherwise---any ICE engine can use alcohol, although pure hydrous ethanol can be hard to get started in cold conditions----this is the reason for 15% gasoline mix. It can also be remedied by preheating the alcohol until the engine is up to running temp.

      Otherwise, there are two major differences. One, pour some gasoline in a bowl and ignite it. You will get a massive cloud of thick black, acrid smoke. Pour some alcohol in a bowl and ignite it. You get a clear blue flame and no smoke at all. The same thing happens inside an engine---that is why you get almost no pollution at all from an engine burning alcohol vs. one burning gasoline. The alcohol burns completely, the gasoline does not. Most of the soot(smoke) from the gasoline ends up in the oil----that is why it turns so black after just a few thousand miles. Change the oil in an engine that runs on alcohol, and the oil is almost the same color it was when you put it in----alcohol does not produce the pollution that gasoline does-----and the engines last MUCH longer, the oil lubricates better when it is not contaminated. THAT is why car companies would rather have you driving cars that run on gasoline. You'll have to buy a new car MUCH sooner than if you drive your car using alcohol.

      The key to engine efficiency with an Internal Combustion Engine is compression. The higher the compression ratio, the higher the power output, and the higher the efficiency. The key to higher compression is the fuel that you use. Octane is the rating that compares the ability of a fuel to withstand higher compression without preignition(knock--fuel igniting too soon in the cylinders). The octane of gasoline is 85-87----the octane of ethanol is 115. With gasoline engines, you can only get about 9 or 10:1 compression ratio before you start getting knock. With ethanol, you can go to 24:1 compression before you start to get knock.

      That is why the fastest, most advanced race cars in the world---the Indy League Circuit all run on 100% ethanol. They use a 3L, Honda V8 engine that typically develops 1200 to 1600 bhp. From an engine with a displacement smaller than most V6s on the road---Indy race cars develop more horsepower than 4 typical 18 wheel OTR diesel rigs. That is why Indy racers use 100% ethanol-----and have for over 45 years. Gasoline can't even come close to producing anywhere near that amount of power----and even if they did, would burn up the engines in just a few laps by friction caused by oil contamination and breakdown.
