EPA: What could go wrong?

United States Environmental Protection Agency (EPA) officials, testifying to Congress on Wednesday implied that automakers like Ford Motor Company (F) and Toyota Motor Company (TYO:7203) were lying when they said higher ethanol blends could corrode seals, fuel lines, and engine components, voiding warranties.

I. EPA -- We Know Better About These Cars Than the People Who Built Them

The EPA is convinced that it knows about the risks better than the automakers who built and tested the cars.

At issue is the question of whether the EPA can authorize E15 fuel -- a 15 percent ethanol, 85 percent gasoline -- mix to be sold at pumps, with special stickers to warn customers.  E10 fuel, which contains a smaller 10 percent fraction of ethanol, is currently mandated by many states.  Approving E15 would clear the way for states to possibly mandate it as the exclusive fuel.

Margo Oge, director of the agency's Office of Transportation and Air Quality office, claims that her researchers conducted "extensive" tests using E15, which showed, "no unusual damage was found compared to control vehicles tested with normal gasoline."

Thus far General Motors Comp. (GM), who produces E85 (85 percent ethanol) capable FlexFuel vehicles, has been the only automaker to voice enthusiasm about the proposal.  The rest of the major U.S. and foreign automakers have complained that E15 could destroy engines in cars produced in 2001 or later.

Essentially, both sides are calling the others a liar in the dispute.

II. Ethanol Opposition is Solidifying

There are signs that opposition to the proposal is mounting in Congress.  Rep. Andy Harris (R-Maryland) blasted the measure, stating it wasn't a "science-based decision".

Overall, while green technologies like cellulosic ethanol seem promising, the case for the U.S.'s current ethanol supply -- corn ethanol -- isn't particularly compelling.  Corn ethanol has been shown to raise food prices and delivers worse gas mileage (ethanol exclusive engines can deliver better mileage, but mixed engines deliver worse performance when burning ethanol).  

Some studies have also shown that it produces more polluting gases, such as nitrogen and sulfur-containing compounds, than gasoline over its life cycle, thus deteriorating air quality.  Similarly, it produces more carbon emissions than gasoline.

Still, farming states have managed to push corn ethanol onto the nation.  The move paid off for a lucky few -- corn farmers grew wealthy the recipient of billions of dollars in subsidies and the politicians they donated to were reelected. 

However, the good times for corn ethanol proponents appear to be coming to an end in the U.S.  Just weeks ago the U.S. Congress repealed the $5.6B USD in incentives for corn ethanol.

The corn your talking about is termed "Dent Corn", you can identify it by the dimple at the top of the kernel. And yes, if you eat it raw it will kill you though the 3 "D"s. Disentary, Diarea, Death.

However you happen to eat it all the time. Corn meals and most Mexican applications (think Masa which used in just about everything) process the ground corn using a lye soak to remove the toxins. After processing it is perfectly safe. You not going to die from binging on Doritoes.

Sweet corn is usually sold directly on the cob or canned. But is a very small percentage of the US corn harvest.

Secondly, it doesn't "slowly" kill cattle. Corn fed beef is fed straight unprocesed dent corn. Most cattle are harvested at 18-22 months of age. They die perfectly healthy, its the slaughter house that gets death going for the cow.

We've got 20 year old corn fed breeding bulls on my brothers farm in Colorado that are pefectly healthy.
