{ "item_title" : "The Machine That Moves Electricity", "item_author" : [" Douglas Donovan "], "item_description" : "Flip a switch, and light appears. Behind that simple act sits a machine most Americans have never consciously seen and could not name if asked: the power transformer. It is the device that made Thomas Edison's direct-current dream obsolete within a decade, the device that let a single power plant at Niagara Falls light cities two hundred miles away, and the device now sitting at the center of America's most urgent energy bottleneck.In The Machine That Moves Electricity, Douglas Donovan traces the transformer from Michael Faraday's induction ring and the War of the Currents through the giant 400-ton units that had to be shipped by rail and barge to build the modern grid, into the factories struggling today to keep pace with a once-unthinkable surge in demand. Utilities that ordered transformers in 2021 are still waiting for delivery in 2026. Electrical steel, copper, and skilled labor have become as strategically important as the semiconductors that dominate the headlines-and just as scarce.Written in the same accessible, deeply researched style as Donovan's A History of the United States Electrical Grid and The Reliability Frontier, this book stands on its own as the definitive popular account of the machine that quietly makes modern life possible, while completing the trilogy's picture of an American grid straining to meet an electric future nobody fully planned for.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/1/08/815/285/1088152856_b.jpg", "price_data" : { "retail_price" : "15.99", "online_price" : "15.99", "our_price" : "15.99", "club_price" : "15.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
