Who First Used It?
• Ford Motor Company
• Henry Ford’s Model T

When & Where Was It First Used?
• 1908
• The United States was first to make working corn ethanol fuel cells in cars
![Page 4: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/4.jpg)
Why Did It Develop As An Energy Source?
• Corn Ethanol is better for the environment than regular gasoline
• With fossil fuels quickly diminishing, another fuel source was needed
![Page 5: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/5.jpg)
How Did They Develop Or Create It?
• Corn ethanol is developed in two ways: dry mills or wet mills
• Dry mills are less expensive then wet mills but cost more energy

Step 1
• After being cleaned in the wet mills, the corn is then taken to be steeped
• This process softens the kernel of corn for milling
![Page 8: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/8.jpg)
Step 2
• After steeping, the corn is then moved through a machine that splits up all the parts of the corn
• The gluten is separated from the starch by centrifugation
![Page 9: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/9.jpg)
Step 3
• The pure starch is now ready to become ethanol
• Enzymes are added to the starch to hydrolyze the starch to fermentable sugars
![Page 10: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/10.jpg)
Step 4
• Then yeast is added to start the fermentation process
• After two days, the fermentation broth is then distilled where about 95% of the distilled broth is created into absolute ethanol

Current Uses
• Corn Ethanol is used in all types of automobiles as a fuel, similar to regular gasoline
![Page 12: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/12.jpg)
Where Is It Currently Being Used?
• Corn ethanol is mainly used in the U.S.
• The U.S. had large areas of crop land and is able to produce a good amount of corn for food and fuel
![Page 13: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/13.jpg)
What Are The Future Plans?
• Making every new car that is produced E-85 (Corn Ethanol gasoline) compatible
• Finding new, more efficient ways to produce Corn Ethanol
![Page 14: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/14.jpg)
Benefit #1
• Much better for the environment than regular gasoline
![Page 15: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/15.jpg)
Benefit #2
• Produces less harmful emissions than other fuel sources
![Page 16: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/16.jpg)
Benefit #3
• Corn is a renewable resources, unlike fossil fuels
![Page 17: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/17.jpg)
Benefit #4
• Corn ethanol is less toxic in car exhaust than in regular gasoline
![Page 18: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/18.jpg)
Benefit #5
• Corn ethanol is better for the U.S. because it doesn’t require as mush dependence on imported oil
![Page 19: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/19.jpg)
Drawback #1
• Corn ethanol production is labor intensive and can be affected by bad weather
![Page 20: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/20.jpg)
Drawback #2
• It is more difficult to produce Corn Ethanol than it is to produce regular gasoline
![Page 21: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/21.jpg)
Drawback #3
• Corn ethanol reduces soil carbon that possibly contributes to warming
![Page 22: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/22.jpg)
Drawback #4
• The process of making corn ethanol uses corn which is a major crop used for food
![Page 23: Corn and its goodlyness](https://reader038.fdocuments.us/reader038/viewer/2022102900/54be54894a7959a4548b479d/html5/thumbnails/23.jpg)
Drawback #5
• Corn ethanol, coupled with consumption can be as worse as gasoline consumption
