they use corn to make fuel while it would be much much easier to produce ethanol with hemp..
Yes it is and it is quite the versatile product. Industrial hemp has many uses but getting a buzz is not one of them. It's called ditch weed around here and into western Indiana. In Illinois they kill it, in Indiana they stake it out and bust the people harvesting it.I guess hemp is part of the "war on drugs" we have been losing for decades.
It's true that ethanol doesn't contain as much energy per unit volume as gasoline. Ethanol is blended in to reduce emissions that are harmful to human health, not to reduce carbon dioxide emissions or get you better gas mileage.Corn is the staple of the American diet. Turning "food" into fuel makes no sense.
The creation of corn ethanol requires more energy to produce than the energy liberated later on when we burn it. This makes no sense. Brazil has proven "sugar ethanol" does make sense, however.
Ethanol has a lower energy content and hence lower mileage. I would postulate MORE pollution as a result of the lower mileage.
This is nothing more than a political boondoggle started by GW Bush and extended by the current regime. Once again, market distortion.
Ethanol was originally used to reduce emissions. But emission control is so much better now it is not needed. It's really nothing but a boondoggle anymore and no need to use it as a motor fuel.It's true that ethanol doesn't contain as much energy per unit volume as gasoline.

It still does reduce emissions. By using the word emissions I'm not referring to the non-toxic water and carbon dioxide, I'm referring to carbon monoxide, particulate matter and other chemicals that are toxic to humans. Adding ethanol makes the oxidation of gas more complete and reduces the harmful emissions I just listed.Ethanol was originally used to reduce emissions. But emission control is so much better now it is not needed. It's really nothing but a boondoggle anymore and no need to use it as a motor fuel.
Much better uses for corn out there than spending $4 to make $4.50 worth of fuel, and get worse gas mileage and mess up small engine carbs.
Well we're I'm from ethanol in gasoline was only legislated in 2007, so I don't think that much has changed since then. Do you have any facts from credible sources to back up what you say?Oxygenateors are not needed with the cats, variable cams and precise ECU control they have today.
All that article does is question things and says increasing the minimum to 15% may do something. It's good to question things, but that's not proof that adding 5-10% ethanol doesn't work.It was introduced in the 70s to help with the pollution. I believe emission control has advanced quite a bit since then. I don't see how it improves the emissions just because there is an O atom attached when you can precisely control the fuel O2 ratio now.

You realize ethanol cannot be transported in pipelines? This means it all has to be trucked or by train.
I read that article and the conclusions you are drawing from it are incorrect. That article says nothing about the reduction in toxic emissions when burning ethanol blended gas. You can't just add more oxygen to the fuel air mix to achieve the same results.If you want to add O2 to the fuel mix then just open the throttle. In the end ethanol is a net loss in petroleum and a gross polluter when used as an automobile fuel. It only helps older cars that have ancient emission control.
Ethanol Fuel from Corn Faulted as ‘Unsustainable Subsidized Food Burning’
When you burn gasoline combustion is always incomplete. You also get by-products because of impurities in the gas. Think of what happens when you burn a piece of wood. Most of the mass turns into carbon dioxide and water while a lot of ashes remain as incompletely combusted wood. The exact same thing happens when you burn gasoline. Catalytic converts help convert some of the by-products to less harmful forms but can only do so much. When you blend in ethanol you reduce the amount of unburned gas.What does ethanol do to the combustion process?
Adds an O atom, increases octane. Just how does it reduce deadly emissions on a new car? It requires more fuel per mile, about 5% from what I see. Some new cars actually leave the air cleaner than what went in depending on where you live.
