Corn and its goodlyness

  1. 1. By: Ethan Carabin & Sam Foster CORN!!!
  2. 2. Who First Used It? <ul><li>Ford Motor Company </li></ul><ul><li>Henry Ford’s Model T </li></ul>
  3. 3. When & Where Was It First Used? <ul><li>1908 </li></ul><ul><li>The United States was first to make working corn ethanol fuel cells in cars </li></ul>
  4. 4. Why Did It Develop As An Energy Source? <ul><li>Corn Ethanol is better for the environment than regular gasoline </li></ul><ul><li>With fossil fuels quickly diminishing, another fuel source was needed </li></ul>
  5. 5. How Did They Develop Or Create It? <ul><li>Corn ethanol is developed in two ways: dry mills or wet mills </li></ul><ul><li>Dry mills are less expensive then wet mills but cost more energy </li></ul>
  6. 6. Diagram
  7. 7. Step 1 <ul><li>After being cleaned in the wet mills, the corn is then taken to be steeped </li></ul><ul><li>This process softens the kernel of corn for milling </li></ul>
  8. 8. Step 2 <ul><li>After steeping, the corn is then moved through a machine that splits up all the parts of the corn </li></ul><ul><li>The gluten is separated from the starch by centrifugation </li></ul>
  9. 9. Step 3 <ul><li>The pure starch is now ready to become ethanol </li></ul><ul><li>Enzymes are added to the starch to hydrolyze the starch to fermentable sugars </li></ul>
  10. 10. Step 4 <ul><li>Then yeast is added to start the fermentation process </li></ul><ul><li>After two days, the fermentation broth is then distilled where about 95% of the distilled broth is created into absolute ethanol </li></ul>
  11. 11. Current Uses <ul><li>Corn Ethanol is used in all types of automobiles as a fuel, similar to regular gasoline </li></ul>
  12. 12. Where Is It Currently Being Used? <ul><li>Corn ethanol is mainly used in the U.S. </li></ul><ul><li>The U.S. had large areas of crop land and is able to produce a good amount of corn for food and fuel </li></ul>
  13. 13. What Are The Future Plans? <ul><li>Making every new car that is produced E-85 (Corn Ethanol gasoline) compatible </li></ul><ul><li>Finding new, more efficient ways to produce Corn Ethanol </li></ul>
  14. 14. Benefit #1 <ul><li>Much better for the environment than regular gasoline </li></ul>
  15. 15. Benefit #2 <ul><li>Produces less harmful emissions than other fuel sources </li></ul>
  16. 16. Benefit #3 <ul><li>Corn is a renewable resources, unlike fossil fuels </li></ul>
  17. 17. Benefit #4 <ul><li>Corn ethanol is less toxic in car exhaust than in regular gasoline </li></ul>
  18. 18. Benefit #5 <ul><li>Corn ethanol is better for the U.S. because it doesn’t require as mush dependence on imported oil </li></ul>
  19. 19. Drawback #1 <ul><li>Corn ethanol production is labor intensive and can be affected by bad weather </li></ul>
  20. 20. Drawback #2 <ul><li>It is more difficult to produce Corn Ethanol than it is to produce regular gasoline </li></ul>
  21. 21. Drawback #3 <ul><li>Corn ethanol reduces soil carbon that possibly contributes to warming </li></ul>
  22. 22. Drawback #4 <ul><li>The process of making corn ethanol uses corn which is a major crop used for food </li></ul>
  23. 23. Drawback #5 <ul><li>Corn ethanol, coupled with consumption can be as worse as gasoline consumption </li></ul>
