Originally posted by Phil1 'It's not a panacaea, but if the process of growing and converting the corn can be made greener, then you have a combustible carbon neutral fuel which can store energy for things like vehicles in a portable way. (For the meantime, at least it can fuel a car off the dreaded coal without paying Saudi Arabia) But it won't be 'green' until that process can be made to use more sustainable energy (and hopefully biomass) inputs. See?'
Ahhh no. We have no coal fueled cars here at least in this part of the country and I have been in the automotive field on a manufacturing level for only 47 years. I think the Saudis are big in oil.
The ethanol formula is:
C2H5OH.
C= carbon
Biodiesel and most any other 'bio' is carbon based.
Corn ethanol fuel is a subsidised waste and will die a natural death without gov't cash keeping it afloat. It cannot compete with gasoline/diesel at anything less than $5-6 a gallon gas in the real world.
You're not hearing me.
Making ethanol from corn ends up using just as many fossil fuels, to grow, fertilize, and process that corn into ethanol. That's why the ethanol thing turned out to be just another way for Big Oil and agribusiness to greenwash: but it wasn't supposed to stop there.
What are presently fossil fuel inputs that come out about even by the time you burn the corn crops... don't have to be fossil fuel inputs. And the biomass doesn't have to be food crops.
But the big money and Bush halted things there.
You can process even corn into ethanol by using any energy input for that process: that includes coal or, hopefully, something more sustainable. You could run those plants off wind farms, even. Then you'd start seeing benefits... If you have a place to sell the ethanol.
If you have a place to sell the ethanol, there is a reason to *make* the ethanol.
No, you don't turn *coal* directly into ethanol, but you can at least use it to run the conversion plant. Not that it's clean, but at least the coal is domestic.
And we can do better.
Again. *get it?*
