Ethanol-blended gasoline--Help

My twgn is politically sensitive and is demanding that the ethanol be made from organically grown, but not-genetically-modified corn. :roll:

I'm confused.

ALL pump gas has some percentage of ethanol, and it's impossible to know where that ethanol comes from.

Your twgn doesn't happen to be a hippie, does it?

I can see why there would be a concern with genetically-modified corn, but it shouldn't matter if it's organic or not.
The problem with genetically-modified plants is that the crops will cross-breed with other crops nearby. Even DNA from sterilized plants will appear in the DNA of offspring of nearby plants, which could be grown by the same or a different farmer for other purposes, reducing the value of their crop. Another problem is that the genetically-modified plants have an advantage over the native species and can replace them outright. For example, Taiwan has no native wild rice left in it's country. There is rice growing wild in Taiwan, but it's genetically-modified and resistant to attempts to eradicate it. Even those interested in genetically-modifying the rice are concerned as a non-modified stock is needed to begin the modification process with.
But why organic if it's used for fuel? Are algal blooms or groundwater pollution a problem?
by the way, what is a twgn?

Wow. I don't think any of those are on my reading list. However I'll be sure to PM you if I ever have to take chemistry in future semesters.

btw- twgn is short for Turbo Wagon. : Look at all the education being spread in this thread! :-)

Turbo Wagon.
*slaps forehead*
I should have realized that one.
Are there still places that are required to add ethanol to the gasoline?

Not a fan of ethanol/politics associated with it. My cars were not made to run on ethanol. Nor were my power tools. I'd see it as an option for consumers to choose, but mandating it's use causes gas prices to go up. BTW ethanol is more expensive right now than gasoline. Has been for a while too.

With thousands likely to die during a recent famine in Africa, the U S was preparing to donate corn. The European media and cultural mob said "No!". The reason was that the corn might have been genetically modified and therefore hazardous to the long-term health of a population that was starving to death.

BAC5.2 -- Yes, it seems that my twgn has been a closet hippie-- does this raise or lower the value of my car? :roll:

Everyone is. Most are E10.

Subtle - I think being a closet hippie raises the value for the Subaru community.
