Energy balance in the United States

One study has concluded that the use of corn ethanol for fuel would have a
negative net energy balance. Namely, the total energy needed to produce
ethanol from grain - including fermentation, fertilizing, fuel for farm
tractors, harvesting and transporting the grain, building and operating an
ethanol plant, and the natural gas used to distill corn sugars into
alcohol - exceeds the energy content of ethanol. However, all subsequent
studies have concluded that ethanol production yields more energy than it
consumes (most agree on a ratio of 1.34:1) This is remarkable when one
considers that the two primary sources of fuel for transportation (diesel
and gasoline) have a negative energy balance. Both consume about 20% more
energy than they yield. [9]
Does this mean that after I eat my corn I can shove the corncob in my
gas tank?

TIA

I had always heard the reason for NOT using Ethanol was that it took more
energy to produce than was returned. i never heard this about fossil
fuels.

So, what's the holdup, then?
Oil Cartel?

There is no holdup. For the last year, we have been averaging the building
of 2 ethanol plants a year. By my house, you can buy e-85 for about 70 cents
less a gallon than regular gasoline.

I just wish Toyota would pull their heads out of their asses and make their
cars compatible with it.

I meant a month... not 2 new plants a year... but two new plants a month

Why isn't the car compatible with it? Mods are needed to run ethanol?
Yeah basically you need to get rid of anything in the fuel system that could
possibly rust. You also have to program the computer to work with the higher
octane and lower BTU of ethanol. A properly programmed car will only lose a
little less MPG.
