1. 1. What is it?3. Where does it come from? 2. Why do we use it? 4. How does it work? 6. How does it change us? 5. How does it change? 7. How do we change it? 8. What are its costs & benefits? 9. How do we evaluate it? 0. Introduction You are here

2. Review: What is nanotechnology? Nanopowders and nanomaterials (pants, sunscreen) Molecular precision (solar cells, light emitting diodes) Nanoscale machines (none yet) Matter compilers (read Diamond Age) Self-replicating robots (read Prey)

3. Why do (or will) we use Nanotechnology? 1.Food 2.Shelter 3.Communication 4.Transportation 5.Commerce 6.Art 7.Religion 8.Health 9.Entertainment 10.Organization 11.Conflict 12.Exploration

4. Why do (or will) we use Nanotechnology? 1.Food (detects when food is spoiled http://www.packworld.com/articles/Features/18256.html) 2.Shelter (aerogel insulation now, diamond windows later – see Diamond Age) 3.Communication (optical switching) 4.Transportation (space elevator http://www.nanotech-now.com/Art_Gallery/LiftPort.htm) 5.Commerce (matter compilers could create products where needed, selling only designs) 6.Art (Maya Blue 1200 years ago) 7.Religion (who’d have expected GPS to be used to find Mecca? http://www.primidi.com/2004/08/16.html) 8.Health (Nanomedicine by Robert Freitas at http://www.nanomedicine.com/NMI.htm) 9.Entertainment (display phosphors, utility fog http://discuss.foresight.org/~josh/Ufog.html) 10.Organization (pervasive surveillance for law enforcement, contact lens HUD) 11.Conflict (nanoscale sensors, both stationary and mobile) 12.Exploration (lens for evanescent waves to view atomic scale, smaller space probes)
