I had a longer review, which got eaten by a refresh page, so tl;dr, this is an okay but light popular history, with Westinghouse and AC as the protagonist. It's best talking about the sensational safety maneuverings around the battle of the currents, including the first execution via electric chair, and gruesome public demos where dogs and horses were electrocuted, but it has a rather surface level take on technology and corporate politics. Still interested to compare electricity in 1890 to dotcoms in 1990, and contemporary Silicon Valley excess, and this book is probably more readable than David Nye's Electrifying America.
