"The best fuzzy rules, the best knowledge, deal with the turning points of the system. If a race-car driver teaches you how to drive, you don't need him to show you how to drive on the straightaway. It's how he handles the curves that matters."
- Bart Kosko

Sunshade-Photocell Collector  
  A fanciful design for a device that gathers solar energy.  

This device has two functions; it gathers needed energy and provides needed shade to people.

Then he saw the geek - a codger this time - leaning against one of the slender stalks of a sunshade-photocell collector, looking directly at the three of them.
