• Resumen

  • Battersby details how the electricity grids are facing an all-out avian bombardment. A dirty war is raging across the globe. Enemy air strikes target their vast networks of power lines) transmission towers and substations. The grid was engineered to withstand the most ferocious lightning strikes, but struggles to resist these unrelenting assaults. For almost a century the network has been shaped by an arsenal of weaponry developed to counter this formidable foe: bird droppings. The first major assault occurred in California in 1923, along transmission lines strung for 390 kilometers between the Big Creek hydroelectric plant and the power-thirsty city of Los Angeles. Southern California Edison was one of the first companies to upgrade Us lines from 150 to 220 kilovolts.
