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)
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)
