Transcription de la présentation

  1. Date: 2/4/10Prepared by: Javier Kienzle, Fellow - GK12  ProgramPresented at: Columbia High SchoolSupported by:  NSF Graduate Teaching Fellow in K-12 Education ProgramAssociated Institution: Stevens Institute of Technology - Hoboken, NJ Sources: NAE, NRC (2009) The Fourteen Grand challenges of engineering

  2. Keep in mind… “Although engineers cannot solve these challenges alone, neither can the challenges be solved without engineers.”

  3. Making Solar Power Economical • There is a natural efficiency for converting solar energy to electricity. • This limit is imposed by material properties.

  4. Providing Energy from Fusion • In essence, fusion is the opposite of fission (nuclear reactors) • E = mc2 • Requires 100 million Kelvin!

  5. Developing Carbon-Sequestration Methods • CO2 pollution is a big problem • How do we “capture” it instead of releasing it into the atmosphere? • Chemically • Store underground • Reduce emissions

  6. Managing the Nitrogen Cycle • Nitrogen is abundant in out atmosphere, and essential for life. • Humans have made an impact: nitrogen overload • Fertilizer • Fossil-fuels

  7. Providing Access to Clean Water

  8. Restoring Urban Infrastructure

  9. Reverse-Engineering the Brain

  10. Preventing Nuclear Terror

  11. Last but not least… • Engineering better medicines • Advancing health informatics • Securing Cyberspace • Enhancing virtual reality • Advance personalized learning • Engineering the tools of scientific discovery
