This is a project for one of my MBA core classes: Organizational Behavior.

  • I am so pleased that I found you! I have suffered from Sleep Apnea for years. I have tried everything to fix the problem but nothing has worked. For the last years I have been trying to use a CPAP machine on and off but it is very difficult to sleep with. It's noisy and very uncomfortable. I had no idea there was a natural way to help me. I am so pleased that I found you! ■■■ https://bit.ly/37PhtTN

A Greener World Via Nanotechnology

  1. 1. A Greener World Via Nanotechnology<br />
  2. 2. Increasing World Population: Currently 6.8 billion as of April 2010<br /> Projected to be 9 billion by 2050<br />Malthus Theory<br /><ul><li>Stated that population would eventually outgrow its ability to sustain life and could not produce at appropriate levels (agriculturally and economically)
  3. 3. Has been proven inaccurate through innovations and technology</li></ul>But as population increases…<br /><ul><li>Increasing Pollution
  4. 4. Increasing Health Hazards
  5. 5. Decreasing Natural Resources </li></li></ul><li>Call 911!<br />
  6. 6. Which brings us to our problem…<br /><ul><li> How will humans be able to support the world’s population growth rate, provide all the necessities required for life, and not destroy the earth (or each other) in the in the process?</li></ul>…and our potential solution…<br />
  7. 7. Nanotechnology<br />
  8. 8. “Microscopic scale” manipulation of materials<br />
  9. 9. Why It Is Important?<br /><ul><li> Increased strength
  10. 10. Better performance
  11. 11. Intelligent materials
  12. 12. Shrinking stuff</li></li></ul><li>See The Picture Below?<br />One Strand of Hair = One Billion Nano-Particles!<br />
  13. 13.
  14. 14.
  15. 15. Energy<br />
  16. 16. Currently<br /><ul><li>30 billion tons of carbon dioxide emitted yearly
  17. 17. Average American emits ~50,000 pounds of CO2 each day
  18. 18. In 2004, world required 220 million barrels of oil per day to run the world (equal to 14.5 terawatts)
  19. 19. Terawatt = 1,000,000 megawatts</li></ul>The Future of Energy Consumption<br /><ul><li>Estimated that we will need 60 </li></ul>terawatts by 2050!<br /><ul><li>Nanotechnology is giving alternatives </li></ul>to burning fossil fuels (solar and wind)<br /><ul><li>And nanotechnology is enhancing </li></ul>current energy generation methods<br />
  20. 20. Conventional Methods of Energy Generation<br /><ul><li> 70% of all energy generated in the world was done so by the use of nonrenewable energy
  21. 21. 45% was generated by coal, 24% by natural gas, and 1% from petroleum
  22. 22. All three of above forms of electricity generation are done so using mechanical energy that forces an electrical generator to rotate (called turbines) through the use of heat, albeit burning the fossil fuel
  23. 23. Nanotechnology is helping increase the operation temperatures of materials, and reduces cracking</li></li></ul><li>
  24. 24. Solar Energy<br /><ul><li> Generation of electricity from sunlight (either direct or indirect)
  25. 25. Direct method is referred to as photovoltaic (PV)
  26. 26. PV panels collect the suns energy and transform it into usable electric current
  27. 27. Has evolved from powering watches and calculators into big business
  28. 28. Has doubled in energy production every two to three years
  29. 29. Nanotechnology helps efficiency through nanostructured anti-reflection layers which yield more light</li></li></ul><li>Wind Energy<br /><ul><li> Converting the earth’s atmospheric movements into useful energy using wind turbines, wind mills, and wind pumps
  30. 30. Very clean, renewable, distributed across globe, but it is also aesthetically unappealing ,loud, require frequent maintenance, and energy generated must be taken immediately
  31. 31. Nanotechnology is helping reduce weight, improve strength, and shed lightning strikes, and coating which reduce mechanical noise and increase longevity of parts</li></li></ul><li>Nano’sEnergy<br />
  32. 32. Consumer & Intermediate Goods<br />
  33. 33. Currently<br /><ul><li>Batteries – Disposal Problems</li></li></ul><li>Nano<br /><ul><li> Higher energy content
