  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? • Food • Shelter • Communication • Transportation • Commerce • Art • Religion • Health • Entertainment • Organization • Conflict • Exploration

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