Our systems of infrastructure are not only shrouded in mystery, many are woefully out of date. In On the Grid, Scott Huler takes the time to understand the systems that sustain our way of life, starting from his own quarter of an acre in North Carolina and travelling as far as Ancient Rome. Each chapter follows one element of infrastructure back to its source - or to its outlet. Huler visits power plants, watches new asphalt pavement being laid, and traces a drop of water backward from his faucet to the Gulf of Mexico and then a drop of his wastewater back to the Atlantic. He reaches out to guides along the way, both the workers who operate these systems and the people who plan them. Mesmerizing and often hilarious, On the Grid brings infrastructure to life and details the ins and outs of our civilization with fascinating, back-to-basics information about the systems we all depend on.
