There is a misconception out there that nanotechnology is really for electronics.  I guess the word “technology” makes people think that.  You can point out that there is nanotechnology in pants, tennis balls, ski goggles, batteries, etc.   Penn State’s NACK (Nanotechnology Applications and Career Knowledge) website, Nano4me.org has an introductory modules that discuss products that have nanotechnology.  Add this for the car windows from the Nanotechnology Development Blog:

nanotechnology has been used in improving visibility through car windscreen especially during rain of fog. Nanotec has developed a unique nanomaterial, which is transparent and creates water repellant and non stick glass surface. the windscreen and window glasses treated with this nanomaterials significantly improves visibility.

Just another example of how nanotechnology is not just for electronics.
