I agree. Corn is horribly inefficient. Sugar is where it's at. We need to invade Cuba.
15% ethanol for gas engines? Are you kidding me!

I thought this thread was about the Corn Syrup lobby that makes us use Corn Syrup instead of real sugar in our sodas and fruit juices.
Let's not waste time with converting for Ethanol, we've got the whole Eastern coastline ready to open up for real oil!
Not surprising, as long as bribing politicians is legal.
Nearly all US corn and soybeans are now genetically modified, which is completely for the benefit of the corps, esp Monsanto, not in any way for the benefit of the consumers.
Corps are feeding us, and their animals, pathogenic , and shipping their all world, killing local agriculture.
Shouldn't that read - Americans are such gluttons that they'll eat the nastiest a corporation can put in front of them as long as it's cheap and loaded with enough fat and/or sugar.
LOL...I occasionally run M85 in my van. 85% Methanol. It's ridiculously cheap..usually .75 to $1 cheaper than unleaded.
The kicker is, my mpg is almost cut in half.![]()
I heard once that modern agriculture could pretty much be defined as "the conversion of oil energy into food".
http://www.abelard.org/briefings/energy-economics.php
Look at the table "approximate EROEIs [6] for different energy sources" about halfway through the briefing.
Ethanol offers somewhere between a negative EROEI, that is it takes MORE energy to produce than you get out of it, to about an 8.
Now, the most pertinent bit is the briefing on biofuels, that has some rather good data in it.
http://www.abelard.org/briefings/biofuels.php
There is a good particular chart that shows the amount of energy/fuel in a given hectare (unit of area), but it does not show any of the "cellulose based" ethanols, but the briefing does talk about them in a pretty balanced and fair-minded way.
The end result is that it would, even with the best technology and efficient distillation processes, probably not be very efficient to get fuel from such sources. It would require VERY large amounts of crop land to replace more than a tiny fraction of our needs from it.
It is mostly likely a dead-end for most countries. Brazil manages to get a good chunk of their transportation energy needs from sugarcane, the most efficient of the sources given in the graph and almost twice as efficient per unit of land as corn. Brazil still uses oil, however, and it remains to be seen if the ethanol economy can be sustained over the long term due to concerns about long-term farmland soil depletion.
We are not Brazil however. The amount of farmable land in the US that could sustain sugarcane is much, much less to start with, and we consume much more energy in our transportation sector.
Soda and fruit juices? I wish only that. I think you meant everything.
http://www.abelard.org/briefings/biofuels.phpA litre of ethanol provides about sixty-five percent the energy of a litre of petrol/gasoline.
Converting that into actual figures:
Assume:
Regular gasoline price: $2.80
85% ethanol price: $1.80
MPG regular gasoline: 18
MPG 85% ethanol: 9
The price is dollars per gallon or $/g
The MPG is miles per gallon or m/g
Since both have a common denominator, you can actually calculate the MPD, or miles per dollar, m/$
18/2.8= 6.42 miles per dollar for regular gasoline
9/1.8 = 5 miles per dollar for 85% ethanol.
You can subs ute your own actual figures for my estimates, but the end result should be fairly close in terms of scale.
This is why one must always remember that you cannot subs ute a gallon of ethanol for a gallon of gas.
They are NOT identical in the way that really matters: the amount of USABLE energy. That is the ultimate measure of any energy source.
Talking off-the-cuff with no evidence here, but I think the majority of people will agree that ethanol is a failed idea.
Everything is right. It's in practically all bread products, meat and nearly every condiment you can think of. It's also in many alcohols.
Go to any fast food chain and order any meal combo - there's corn in every bite. The meat (in addition to being unnaturally corn-fed) usually has some sort of corn product added to the beef or chicken. The soda, bun and condiments all have HFCS and the fries have probably been fried in corn oil. It's also in practically everything you buy during your weekly grocery trip, so unfortunately "just don't eat out" isn't as simple a solution as it should be.
How about this. Everyone... Call your congress[wo]man. Voice an opinion.
The corn farmers no longer need a subsidy to [not] grow corn. I lost track of the truth over the matter with corn, but if it's tax break, OK. If there are subsidies, I say eliminate all corn related subsidies. With the mandated 10% ethanol in fuel, there is a known demand for corn.
Interesting read, look who's names are on it:
Letter to Growth Energy
Subsidies and tax breaks are the same ing thing in the end. Whether you pay less taxes or get money and pay higher taxes it ends up as the same god damn thing in the end. I'm not sure why you're so persistent to act as though one is better than the other.
*WTF It's the wrong thread!* post.![]()
No, read 3 posts above mine.
A tax break is allowing one to keep money they earned, a subsidy is giving someone money that someone else earned. There's a difference.
I stopped trying to explain the difference. I just chock it up to another reason why I call them "lib s."
*WTF. I'm an idiot post*.![]()
What difference does it make if the end result is still the same?
No, it matters.
With a tax break, your money can be no greater than your earnings. With a subsidy, your money can be greater than your earning.
My God....
Why am I trying to explain this again.... I must be insane. Afterall, one definition of being insane is doing the same thing over, expecting a different result....
and you ain't got it right yet.
