The Works: Anatomy of a City, by Kate AscherRead about another entry on the list.
Cities may be dreamlands and economic powerhouses, but they are also marvels of engineering. In this beautifully-illustrated book, Ascher uses New York City to give you a lesson in how urban infrastructure works, from water and sewage to power and beyond. A lot of the technology we use today hasn't changed much since the aqueducts of ancient Rome, so it's fascinating to see how millennia-old ideas have intermingled with cutting-edge wiring techniques. Another great book in this genre is Scott Huler's On the Grid, which deals with the infrastructure of Raleigh, North Carolina.
