Anyone care to do the math and figure what Microsoft's profits would have been if they'd moved the same volume of software that the oil companies moved in oil? I'm sure it would error out most calculators!
Personally, I think bio-diesel is the way to go. You can make 20 gallons of it yourself with 2 gallons of ethanol, some lye, a few other minor additives (off the hardware store shelf, btw) and used frying grease.
Because it uses less ethanol, and the grease is a waste product of our MILLIONS of restaurants, it's win-win. Waste products are recycled, it would take less of our cropland for the ethanol portion (since it's roughly 1/10th of the recipe), and it would free us from crude oil dependency. It's not rocket science, you can make it in your garage for about 80 cents to a dollar per gallon.
If you want to be free of the system, you can't count on the system to help you achieve your goal. If you don't want to pay $3-$3.50 per gallon, do something about it yourself, rather than complain about large corporations doing what any company wants to do, i.e. make a profit. Trade your vehicles in on diesels and make your own fuel.
