Looks like some investors are finally starting to wise up. You are going to have a tough time profitably making ethanol that far outside the Midwest - unless of course you charge $6/gal for it. There is a reason that they position ethanol plants within 50 miles of corn supplies.

... nope, it doesn't look like ethanol is getting a totally free ride.

I just caught your comment back at the oil shale thread. I left a reply for you. Amazed!
I assume by now everyone has heard the Bush joke that spawned that thought...
I guess ethanol does have a useful purpose after all. It is going to force us to conserve even faster due to it being mandated. Of course I don't think this is what the administration had in mind when they mandated it. The good news is that the amount we require in our gasoline will increase over the next few years, which will drive prices ever higher and force us into conservation mode.
RR
Correct ?

It runs on present gasoline vehicles unmodified at equal or greater mileage.
It is much less prone to absorption of water removing the need for special storage tanks and pipelines.
Can be made from the same feedstocks as ethanol at greater yield.
Produces useful amounts of hydrogen as a by-product.
Is cheaper to produce than ethanol.
All these claims are from a company promoting its patented process to make the stuff and extrapolating from a pilot plant so due caution is needed in accepting these claims.

"Butanol as a biofuel (http://www.lightparty.com/Energy/Butanol.html) - Butanol solves the safety problems associated with the infrastructure of the hydrogen supply. Reformed butanol has four more hydrogen atoms than ethanol, resulting in a higher energy output and is used as a fuel cell fuel."
I suspect this might be a familiar site to some of you here, is it responsibly run?

Bio-butanol
Butanol has some significant advantages over ethanol, and probably has a better EROI because it is a less polar molecule than ethanol. Of course, we still won't be able to produce enough to make much of a dent in our oil consumption.

Even the Wall Street Journal has come against the current ethanol hype. In an editorial in the 6/17/2006 Weekend edition of the WSJ they discuss why imitating Brazil won't work for the US, and they also cite research by Cornell's David Pimental and Berkeley's Ted PatzekCornell's that indicates that it takes more than a gallon of fossil fuel to make one gallon of ethanol.
Here is a link:

Ah, they are just riding on our coat tails:
Lessons from Brazil
:)
and they also cite research by Cornell's David Pimental and Berkeley's Ted Patzek Cornell's that indicates that it takes more than a gallon of fossil fuel to make one gallon of ethanol...
Sadly, any article mentioning Pimentel is immediately discounted by ethanol proponents. They consider him discredited, so when he is cited they don't believe the article is reliable.
RR
However, if you want to make any headway with an ethanol pumper, best to avoid Pimentel's name. That is the quickest way to have them dismiss your arguments out of hand. That doesn't mean they are correct in doing so, but my objective is to have them listen to my arguments.
